Background:
Hi Top Dog, I have a 6-year-old Yorkie named Joey who is a little on the weird side. He lived in a house with a fenced-in yard for most of his life, and now lives in an apartment. Now, he has become reactive to dogs and barks and lunges when they are within his 100-foot threshold. When we were doing BAT (Behavior Adjustment Training) at the park, he was doing great until, by mistake, I allowed a dog to come into his threshold. Joey sprinted toward him, and before I could bring in the 30-foot line, he rammed into him and tried to bite before I pulled him back. What do you make of that behavior, and is BAT the right therapy?
Answer:
What you’re seeing from Joey is a very strong self-preservation response, not true aggression. It’s his way of saying, “I’m going to show you how big and bad I am before you can get me.” That’s a bluff rooted in insecurity, and it makes sense given the change in his environment. He went from having total freedom in a fenced yard to living in an apartment where he’s suddenly on a leash, surrounded by noises, people, and dogs he can’t escape from. His whole world has changed, and his sense of control has been taken away.
When that happens, the nervous system goes into defense mode. Every approaching dog feels like a potential threat because he no longer has the option to create distance on its own. Because of that shift, BAT isn’t the wrong method, but it’s not the right phase for him right now. BAT assumes the dog can make sound choices when given distance, but Joey’s not emotionally capable of that yet. His worldview is limited, and his decision-making is based on fear, not logic. When we let him “choose” how to respond, he’s going to pick self-preservation every time because that’s what his body tells him to do.
Right now, he doesn’t need options; he needs structure. Giving him too many choices too soon just feeds the problem because it lets him practice what doesn’t work. For a dog like Joey, especially being as small as he is, the world feels even more intimidating. He’s constantly at a size and height disadvantage, which makes his defensive displays feel necessary to him. To change that mindset, the main focus has to shift toward giving him a job and clarity. That means tightening things up and leaning into obedience around triggers. He needs to feel your structure more than your sympathy. Keep him in position, keep him working, and don’t let him practice scanning or fixating. Calm, confident control from you will reduce his need to control his environment. You can still incorporate the concept of counterconditioning, but it should happen in a structured framework, not free choice.
I’d be doing rigid obedience sessions near other dogs at a controlled distance where he can focus without tipping over. Keep him moving, mark, and reward for focus and neutrality. Once that’s consistent, you can start layering in one-on-one socialization in a controlled setting with calm, neutral dogs. Start with parallel walking and only close distance when he’s relaxed. The goal is to rebuild his understanding that other dogs in his space don’t equal danger, they’re just background noise while he works. Down the line, when he’s more stable and his threshold is manageable, you can transition back to a more traditional BAT structure where choice becomes part of the picture again.
