re: In need of dog help

I was/am confident that he knows I'm alpha. In every other aspect of day to day life he submits willingly with merely a stern tone. I just dont know what it is about that bath tub. I haven't tried to drown him or anything. I've had plenty of dogs that didn't like baths, but never get hyper aggressive over trying to take one. He's locked outside right now. He may stay there from now on. I'm just worried that he might do something stupid to hurt one of the kids. He doesn't act aggressively with them no matter how rough they play with him though. I'm just out of ideas.
