The key with Max's aggression is to never let him win. That's why keeping him on the leash in the house has been invaluable. The more consistently I can enforce my ultimate correctness and power, the sooner he'll behave well off-leash, all the time. At this point, even on the leash, every day is a series of challenges from him, in which he tests his boundaries and pushes for control. The important thing to remember in this case is that this control that he seems to be fighting so hard for is not really what he wants. It's not good for him, nor is it fun for him. All it does is reinforce the notion that he has to fend for himself; that I am not a good leader; that the world is big and unmanageable and therefore he has reason to be fearful and aggressive.
Here are the times that Max will challenge me:
- When the cat runs by - his prey drive gets the best of him. Some will say this is natural, but his desire to chase the cat is destructive and not healthy for either of them. It's good practice for the out of doors as well, to ensure that he doesn't bolt after anything and everything that moves.
- When there is food on the coffee table. Or the counter. Or the kitchen table. He has yet to learn the boundary between food left unsupervised and food he is allowed to access. This is partly bad training on my part, because I used to let him lick my plate clean. It's also because, back when he was off-leash in the house, there would be no way to ensure he "lost" that battle. This continually reinforced the idea that, if he tries hard enough, he can enjoy the tasty reward of free food.
- He'll also challenge me with non-food items, like bottle caps, plastic containers, toilet paper tubes and dirty underwear (what IS it with dogs that do this?). All of the above have been victories he's been allowed to achieve in the past, so it takes a lot more work to undo that learning than to never have allowed it to happen in the first place. He has to learn the difference between toys that he is permitted to have, and things that are not toys at all.
- Any time he knows he's escaped my reach. I occasionally let him romp around the house with his leash on but without me holding it. I usually use this time to ensure that commands like "come," "look at me," "sit," and "lie down" all work without the physical manipulation made possible with the leash. This is usually fine. He responds well generally. But again, if the cat runs by, or he bolts up or down stairs, no matter how calm I keep my voice, he figures out that he has the space to do what he wants. I go after him to collect his leash calmly, before he wins any challenges, but that task alone becomes a challenge for him, one in which his aggression comes to the fore. It's also harder for me to keep my temper in circumstances like this, and he feels that frustration from me, which is probably what brings out his rage.
- When I have guests over. He knows my defenses are down. I hate inconveniencing people. He never barks at me for attention if we're alone or with my roommates, because he knows I'll ignore him no matter what, and he won't win. But when there are guests over, my self-consciousness has, in the past, led me to cave sooner rather than later, bribing him or distracting him or putting him away instead of holding my ground. Social gatherings are also a place of anxiety for Max, so even me removing him from the room is a reward for him, and reinforces the idea that barking can solve his problems.
- Any and all times when I am manipulating his body. If I want to remove his eye goops, dry off his paws, put on a jacket, cut his hair, clean his nasty butthole, and MOST OF ALL, cut his nails (a victory i have yet to achieve), he puts up a fight. It starts with just a kind of puppy-like, open-mouthed teethiness, and maybe physically avoiding my touch, but it can quickly turn into snarly wolverine-like Max, which is terrifying, really. I've been pretty desensitized to this kind of aggression coming from him, so I'm never really afraid to approach him or keep trying. But my anger does come out. It's disappointing when a dog you've spent gallons of time and money on, who you love dearly and want in your life, will turn vicious and try to attack you at a time when you're trying to take care of their health. Heartbreaking, actually, wouldn't be too big of an exaggeration. He often brings me to tears in this manner. The key is to keep going, and to practice mild forms of the desired contact at calm moments. And go into every interaction expecting the best. If you start thinking about all the times it hasn't worked, all the scars you already have on your hands and arms, it won't work. He'll go right back into that space, and there'll be no learning. I try to keep him calm for as much of the procedure as possible, so he's still in a functional state of mind. But once he loses his shit, it's important to keep going. Do anything you need to in order to keep the momentum of the task. Employ friends to hold him down, muzzle him, take deep breaths, think of golden retrievers in family movies... just a few of the things I attempt in order to get these things accomplished. He's great with almost all of these challenges now, but not consistently. *sigh* We'll get there.
In all of these cases, the speed with which I respond and the calm that I embody makes the challenge subside within a smaller amount of time. If I hesitate, if I am angry or frustrated, embarassed or nervous, or if I don't notice until he's already rewarded himself in some way, the challenge will come up again and again, and even defeating that instance will take a much longer time and incite more aggression and frustration from him. So it's a full-time job.
Another thing I've learned is that if Max knows what he needs to be doing, he relaxes and is less likely to get distracted or attempt to challenge me. The key to this is to talk to him. I tell him to lie down if I ever plan to be in any place for a period of time. If I'm sitting on the couch, he earns the right to sit next to my by first lying on the ground by my feet comfortably. The added command of "upup" (onto the couch) "lie down" again is additionally helpful. If ever I want to step away for a moment without dragging him with me, I get him to follow a couple of commands, ending either in "sit" or "lie down," and then i tell him to "wait." He's become quite skilled and patient with "wait," even in the face of distractions. This is a hard one to enforce, but he learned it before with treats. They understand the passing of time, and realize quickly that, if them moving means a longer wait for reward, moving's a bad idea and they should hold absolutely still. At this point, Max is also conditioned to understand my "no" voice and what it means. He doesn't want to hear that voice, not out of fear, but because this has previously meant the absence of a reward, or an increase in his level of subordination. He understands that when I say "no," I'm upset with him for not fulfilling his responsibility to me as top dog, and it's finally becoming clear to him that he doesn't want to let me down. Which is nice. I would say this is a promising first sign of a dominant aggressive dog letting go of some of his dominance and accepting leadership.
