THE OTHER END OF THE LEASH

Earlier I wrote that you “can’t reinforce fear” and used a dog who is afraid of thunder as an example.  For so long we have been told that we’ll just make our dogs worse if we try to comfort them when they run to us in fear when the skies rumble and the rain falls. In this context, it really is doubtful that comforting your dog is going to make him worse. As I said previously, fear is designed to be aversive, and dogs who are terrified of thunder aren’t going to get worse because you stroked their belly.

Indeed, there is research that some interpret to mean that our petting has little effect at all: As I mentioned in a 2008 Bark column (and an alert reader posted), Dreschel & Granger (Applied Animal Beh Science, 2005) found that cortisol levels, a measure of stress, did not decrease when owners pet their dogs during storms. (The most important factor in decreasing cortisol was the presence of other dogs.) However, note that a study by Odendaa & Meintjes (2003, Veterinary Journal) found that cortisol in dogs doesn’t decrease when we are petting them at other times, (although it does in us when we pet them!). However, it is important to remember that cortisol is not the be-all and end-all of indicators of emotion. The authors found that other indicators of internal affect, such as feel-good hormones like oxytocin and prolactin, increased when the dogs were petted, which suggests that stroking did indeed have a positive effect. And hey, if a dog’s behavior changes such that he is no longer pacing and panting while I rub his belly, I’m going to rub his belly!

Here’s an example of fearful behavior from last night at the farm. It’s not about thunder, but it is still instructive: late last night my farmer neighbor was in the field across the street from me in a tractor the size of Connecticut. As soon as Willie heard something and looked out the window, he absolutely lost it. He ran frantically in circles, barking hysterically with his ears pinned, his eyes twice their normal size and a look of sheer terror on his face. When I first heard him bark I honestly thought something terrible had happened, he sounded so horrifically upset. As soon as I saw what it was I said “Will! It’s okay!” and went to him. I used my voice in a soothing way (soft, quiet, looooooooooong notes), sat beside him and asked him to stay still. I rubbed the area between his eyes and the side of his head with long strokes. His barking decreased, although one BOOOOF would still burst out of his mouth every 5-10 seconds at first. In about a minute he stopped barking altogether and stayed still without me helping him. Eventually he put his head down and buried it between my body and my arm. It looked like he was hiding it, and I remember feeling all gooey when I saw that and said “Awww, honey, it’s okay!” but I suspect he was looking as much for the soothing feeling of being cradled as simply hiding his head.

This example brings up an issue that I didn’t address in my first post about reinforcing fear. I should have, but thanks to several thoughtful commentators, I will here. (You can read their comments on the May 4th, 2009 post). They raised the point that surely it IS possible to increase the frequency of a problematic behavior in some contexts, even if fear is one of the motivators. I agree completely that the issue is a bit more complicated that I might have suggested in my first post–ironically I had started to go into it in more depth and then ended up deleting several paragraphs because the post was getting too long and the topic was getting to complicated. But I shouldn’t have, because the topic really does deserve more nuance than I suggested.

The bottom line is you could indeed cause problems by inadvertently reinforcing behavior in certain contexts. There are two things that are important to remember here: one is that fear is an emotion, and “reinforcement” refers to something that increases a behavior. You can’t, technically, reinforce an emotion, but you can increase the frequency of a particular behavior. In the case of thunder phobic dogs I don’t think there is ever a problem, because you are trying to decrease the emotion, which would indirectly decrease the problem behavior. Besides, if you sit beside your dog and stroke him while it thunders, and he stops pacing in circles but sits beside you, then if you are reinforcing anything it is him sitting beside you and not pacing.

Secondly, motivation is key here.  If a dog is barking at visitor from fear, then having the visitor toss treats or toys does NOT reinforce the barking! It decreases it, because the emotion of fear subsides and it is the emotion of fear that drives the behavior. Once the dog associates visitors with treats, her behavior changes to body wags and happy dances. (Visitor = chicken! I love chicken! I love visitors!) This is standard Classical Conditioning, and I can tell you from 22 years of experience that it works incredibly well with lots and lots of dogs. However, if the dog is barking at people not because she is afraid, but because of another reason, it IS possible that you could increase the frequency of the behavior. That’s why it is so important to be able to read dogs and do a good evaluation of a problem behavior. I met a dog once who loved to get right into your face, all body waggy and grinny and relaxed, and then explode in a bark lunge about four inches from your face. I truly believed she just adored it when you startled (I rose at least a foot from my chair), and that is behavior that was clearly being reinforced!

I also think that how you respond to a dog’s fear is critical. First of all, we know that emotions can be contagious, so it is important to not be fearful yourself. Jennifer, in the comments, mentioned the importance of role modeling cool and collected sometimes, and I couldn’t agree more. If I had run to Willie and tried to pet him with an anxious voice and upset affect, it well might have made him more fearful.

Oh, my, I could go on and on, but life continues and I need to get to other things…. But here’s a link to the study on Storm Defender Capes that has just been published (thanks to an alert reader, Chris, for the link!). It looks as though capes in general do indeed have a positive effect, and that there might be something to the Storm Defender cape itself. I haven’t seen the whole study yet, but check it out, even the abstract is interesting. It in Applied Animal Behavior Science.

Meanwhile, back at the farm, it’s been cool and gorgeous and busy. This time of year in the country is never-endingly full of chores. (Did I mention the 150 exams to grade?) The lambs (who, with one exception, are doing beautifully) are thriving but need worming, the grass is growing and so are the thistles which have to be killed one by one, the ram needs to be split out before he breeds Snickers and Truffles, the gardens are full of weeds, the LP tank is leaking, the water tank up the hill needs to be scrubbed out…. and I need to sit in the swing at least a few minutes every day. Can you see it calling to me?

Here’s Sushi this morning. You gotta love the flexibility of cats. I love that Sushi maintained her x-rated yoga pose even while she moved on to licking her legs.

I promised I’d write more about treating thunder phobia in dogs, beyond the earlier posting that it won’t make things worse if you try to comfort them. It’s such a serious problem for some dogs (and their humans), and everyone who has a dog who suffers from it deserves some help (or just support!).

All I can do here is to summarize some of the treatments I have known to work.. a thorough discussion of treatments requires a booklet unto itself . I encourage you to send in comments to let others know what has worked for you, because if there’s one thing I’ve learned, it’s that there is no one treatment that works for all dogs.

Counter Classical Conditioning: This is the first treatment I recommend, and it is especially effective in mild or moderate cases. I’m doing it now to prevent thunder phobia in Will, who is one of the most sound sensitive dogs I know, but so far has not reacted with any anxiety to thunder. In this paradigm (described in a a general sense in The Cautious Canine), you pair something the dog adores (food or play best) with a damped down version of what scares him. Your goal is to condition your dog to associate thunder with something he loves, so that his emotional response to the loud noise is “Oh boy!” rather than “Oh No!” To get this to work:

~ You need to start at whatever stimulus first elicits any sign of fear in the dog. Dogs backward chain storms so well that you can use them as meteorologists… beginning to pace and whine when the wind comes up, and in extreme cases, when the barometer drops long before the storm rolls in.

~ The thunder or other stimulus has to be mild enough to prevent eliciting extreme fear (you can also use CDs or tapes of thunder, but need to have speakers distributed around the room, overhead being best).

~ The “treat” (food or play) has to be highly desirable so that the emotional response it elicits is more powerful than any fear elicited by the thunder.

~ The thunder/noise has to come first… so that it becomes a predictor of something good.

~ You need to proceed in a step-by-step manner, gradually linking louder and louder thunder with the food or play.

In other words, you hear thunder in the far distance, you say “Oh boy! Thunder Treats!” and give your dog a piece of chicken, or throw the ball if they are more motivated by play. Your goal is for your dog to emotionally respond to thunder as a predictor of something good, just like a clicker in clicker training.

Yeah, I know. Believe me, I’ve been through it myself with several dogs. You see the problem here…. how, exactly, does one make arrangements for thunder storms to begin in May with tiny, little quiet thunderettes and then gradually work their way up into glass-rattling boomers once your dog is ready for it? Well, you can’t (if you can, please write soon), but you can give your dog the ‘treat’ (I used food for Pip and play for Luke & Willie) whenever the thunder is relatively quiet, and then just stop once it becomes loud. I’d run outside with Luke and play ball when the barometer dropped and the wind came up, continue playing until the thunder started far away, and then come inside when the thunder began to get so loud that it would overwhelm Luke’s love of ball play. Then we’d go inside, I’d let him hunker beside me, rub his belly, sing and laugh. He got through it in two seasons (I’d call his case a moderate one, not at all severe, while Pip was severe for a few years but came through it fine after two summers of thunder = chicken.).

Pheromone Therapy: I’ve had several clients who had good success with Dog Appeasing Pheromone, or DAP, which is an artificial replicate of the pheromone produced between the mammary glands of a lactating bitch. It is species-specific and has no detectable odor and has the huge advantage of requiring you to buy it and plug it in. Period. Perhaps the easiest behavioral treatment known to science. It has some good research behind it and I’ve recommended it to clients for several anxiety-related problems in dogs and cats (Feliway is the brand name of one of the feline versions) and I’d estimate that it appeared to be helpful in at least half of them.

Acupuncture/Acupressure: I’ve never used this specifically for thunder phobia, but as I’ve said earlier, have used it for a variety of problems with good success.

Wraps: I’d be curious about reader comments on their success with wraps (originally developed by Linda Tellington of Tellington Touch). The theory is that in a general sense, swaddling provides a sense of comfort and safety. More specifically, the speculation is that the continuous neuronal stimulation of the wrap on the dog’s body at minimum distracts him from his fear (a process often called “overshadowing,” in which one stimulus modality dominates an animal’s nervous system) or at best, creates the production of endorphins that de-activate the amygdala and create a sense of calm.

I tried a wrap on Pip and she certainly appeared to be “calm,” but then, that was because she pretty much stopped moving altogether. I wasn’t sure if she was relaxed or in what’s called “tonic immobility,” (or frozen with fear) but after about 10 minutes she lay down and went to sleep, so I relaxed myself and tried it the next time a storm came up. (Use it first before a storm.) It seemed to work miracles at first… she slept right through the next two storms. But wouldn’t you know, the next storm was a barn burner, and it never worked after that. Have you ever tried wraps? (I should add that Pippy looked adorable in an old pink T-shirt! It made me smile anyway!) There are many commercial products available now, but I’ve never seen any research that they would be more effective than wrapping a la Tellington Touch or using an snugly-fitting T-shirt.

A Safe Place: I wrote in For the Love of a Dog about a dog whose job was to protect acres of vegetables from deer, and who became so afraid of thunder he’d run through the electric fence and risk his life on the county highway. I designed, and the owners built, a ’safe house’ for him, and his dedicated human, Barb, spent many a wild night hunkering in his straw covered cave giving him chicken in storms. It worked incredibly well, but it took one amazing woman about two months of dashing 200 yards across the lettuce and beans to get to the safe house before the thunder started!

Safe houses can be created inside houses too… I’ve had several clients who did the counter conditioning in a roomy closet or sound-insulated dog house, and ended up with a dog who was still a bit nervous about thunder, but simply went to her safe house and curled up and slept through the storm.

Sound Therapy: I’ve talked before about the interesting work of Leeds and Wagner in developing music specifically designed to calm dogs. Their work is based on solid biological principles, and I’ve seen many cases in which anxious dogs appeared to be calmed by playing their music. You can read more about it, and get a CD of the music by checking out their book, Through a Dog’s Ear.

Eliminating Static Electricity: Nicolas Dodman suggested a few years ago that part of a dog’s fear of thunder storms could be due to static electricity. One of the blog readers commented that she, in desperation, wiped her dog’s coat with an anti-static dryer sheet, and that it seemed to help. Interesting… I know that Tufts was doing a study of Storm Defender (a wrap that is designed to dispel static electricity), but I haven’t seen the results yet. Any one seen any studies on this yet?

The list goes on.... there are so many things that people have tried. Claudeen McAulifee has a good booklet on treatments from homeopathy to flower essences to melatonin, etc. It’s called the Big Bang! and it’s the only booklet I know of exclusively on the topic of noise phobias. She doesn’t talk about counter conditioning, but goes through many different kinds of non-intrusive treatments (including the use of pink light…… interesting!).

And last, but not at all least, Medication: Serious cases of thunder phobia can be life threatening. I’ve had clients whose dogs ran away, and weren’t found for days, and clients whose dogs jumped out of second story windows, mutilating their bodies in the process. I wouldn’t hesitate to suggest that someone talk to their veterinarian about using medication as a supplement to counter conditioning or other methods if their dog has a serious case of noise phobia. In the most serious cases the veterinarians I’ve worked with have prescribed both a tricyclic antidepressant (like clomicalm) and a fast-acting tranquilizer (like diazepam). In many serious cases, I’ve found over the years that a combination of meds, counter conditioning and a ’safe house’ led to a successful resolution, but I would now add in music from a Dog’s Ear without a doubt.

That said, again, every dog is different, and not all dogs can be cured. As John Paul Scott said to me once, (of Scott and Fuller, and yes, I’m dropping names, I was thrilled to meet him!) not long before he died “Of course dogs are afraid of thunder, to them it sounds like GOD IS GROWLING.”

Meanwhile, back at the farm: Spring is glorious, gorgeous, wonderful and exquisite. it’s amazing how few days like today one needs to make an entire 5 months of winter worth it! There is also so much to do (besides grading 300 pages of essay exams and supevising the grading of another 900) it is overwhelming, but I”m going to focus on the good part!

Here are Tulip’s tulips from the window in the living room, showing the view she had as she overlooked the farm:

I fear you will all get tired of yet another photo of Mr. Will’s bright, expectant face, but it does remind me of spring! (This was taken a week ago, and wow is it different now. The leaves are coming out, the size of a squirrel’s ear, and right on schedule, or a little late, the warblers have arrived this morning. As colorful as any tulip (but too hard to get good photos of for me!). I’ll post more photos of spring at the farm as soon as I can get outside again….

It thundered last week during a rain storm, and it reminded me how much trouble a storm can be in the life of a dog (and for those of us who love them.) Since thunder season is approaching, this seems like a good time to talk about one of the oft-repeated, and ever-so-inaccurate pieces of advice handed out to dog owners: “You mustn’t pet your dog if he runs to you because he is afraid of thunder.”

That’s just wrong. Totally and completely and utterly wrong, but it has gathered gravitas, as things often do, because it has been repeated over and over again.

There are several reasons why that advice is wrong, here’s one of them: Fear is designed to be aversive, that’s why it is an effective way of affecting behavior and keeping animals out of trouble when they encounter something that might hurt them. Fear is aversive enough that no amount of petting or sweet talk is going to make your dog more likely to shiver and shake when she hears thunder rolling as the clouds billow and the rains begin.

Here’s the example for you of how hard it is to “reinforce” fear. What if someone tried break into your home in the middle of the night? Let’s say they did, and after the intruder left, a friend or loved one sat down with you on the couch, brought you tea and gave you a hug. Would the tea and sympathy make you more likely to be afraid if it happened again the next night? Of course not.

Can you imagine someone saying: “Well, I understand that you are frightened, but I’m going to ignore you because any sympathy that I would give you might make you more likely to be frightened if it ever happens again.” I don’t know about you, but that would be my EX friend.

One could criticize this example as one of misplaced anthropomorphism, but the fact is that this process works much the same in dogs as it does in people. The fact is, it is almost impossible to “reinforce fear.” Fear is highly aversive, and if anything, it works in reverse. I suppose, if you did it often enough, you could create an association between thunder and petting that would make your dog afraid of petting, but it is extremely unlikely to go the other way around.

It is true that you can make your dog more afraid than he already is, by doing something yourself that scares him, by forcing him into situations that scare him already or by being afraid yourself. Emotions are contagious, so if you want your dog to be afraid of thunder, then be afraid yourself! But you’re not going to make him more afraid of storms if you stroke his head and tell him it’s going to be okay.

The bad news is that petting won’t help (him or her) much either, so I’ll write next time about how to help a dog who is thunder phobic, but you might also find some ideas in The Cautious Canine, a booklet I wrote about helping dogs conquer their fears in humane and effective ways. I also wrote about why it’s okay to pet your dog when he’s scared in Bark Magazine in October of 2008, and more recently Pia Silvani wrote a GREAT article about it in this month’s APDT Chronicle.

Speaking of emotions, here’s a photo of a boxer with a lot of expression on his face. What emotion would you ascribe to it?

5 AM. I wake up to Lassie’s nails clicking on the floor (wasn’t I going to trim them last night?) as a boom of thunder shakes the farmhouse. Damn.  Why is it that Lassie’s slight discomfort of storms has become more serious as her hearing degrades?  Surely it should go the other way around.

We pad downstairs and lay down together on the carpet, she spooning against me as I stroked her head. (And no, it won’t make her more afraid of storms…. check out my column coming out in Bark magazine soon.)  “Eaa-a-a-a-a-a-a-sy” I crooned, using my voice to help her calm herself.  Why didn’t I bring the CD home from “Through a Dog’s Ear,” a new and fantastic book about the effect of sound on dogs? The CD has music
designed by the authors to calm dogs, and both it and the book are invaluable resources for anyone who is interested in dog behavior.

The authors know what they are talking about.  Susan Wagner is a veterinary neurologist and Joshua Leeds is an expert in psychoacoustics. They got together to investigate the effect of sound on dogs, and to create music that could act to calm nervous canines.  Their work is ‘music’ to my ears (sorry), given that my dissertation research was on the effects of different types of sounds on the behavior of domestic animals.  In brief, I found that short, rapidly repeated notes increased activity, while two different types of notes were used all around the world to slow or stop animals. Long, extended one-noted signals (like “Whooooooooaaaa” and “Staaaaaaay”) were used to slow or calm animals, while one, sharp highly-modulated note (think up and down in a brief period of time) were used to stop fast moving animals (’DOWN!” or “WHOA!).

The research in Through a Dog’s Ear’s follows those same general principles, but adds more, including “harmonic complexity” as well as carefully designed tempos and note intervals.  The authors did research (I can’t wait to see it) that suggested that their calming CD really did settle dogs down.  I talked about this at a seminar I gave in Madison, WI and one participant said her shelter had been using for a while, and it was extremely successful. (So  much so that the dogs who wanted to play chose to go outside, presumably to avoid the effects of the music.) We all listened to the CD, and I swear I had to stop because we all would’ve have gone to sleep. (The authors address that too… they found that dogs settled after just a few minutes, and they could pick up the beat after that to keep the people awake without disturbing the dogs!). I’d love to hear if you have tried it yourself.

I was so impressed with the book that we offer it on our website now (patriciamcconnell.com), but you can get it in lots of places. I haven’t finished reading it yet, but this morning’s storm put finishing it at the top of my reading list.  I’m putting it and the CD in my “take home from the office” bag right now, so that I’ll have it at the farm tonight and tomorrow if the storms come back.

At worst, maybe the  CD will help ME go back to sleep while I cuddle with Lassie through the next set of storms. Here’s my Lassie girl, all fourteen and a half sweet-as-cream years of her.
