Yes, I did compromise. I went with a show/performance line Amstaff rather than a more old school game bred APBT. I sacrificed some drive and working ability in order to try and reduce dog aggression and unattainable exercise requirements.
I did all right with the exercise thing. Rhys will chill and cuddle with the best of them, but is still drivey enough for what I want. He also still has the very happy/silly bulldog personality. He's very goofy and upbeat at the drop of a hat.
The dog aggression thing didn't really work out. He's definitely dog aggressive. He's very much a hot head when provoked. It makes daily life tough- I live in the city and we are constantly exposed to unruly dogs that provoke him. In some ways we have improved a bit on his reactivity, but like any truly dog aggressive dog (AST/APBT especially), his desire to go after other dogs will probably never change or get noticeably better. He's a gladiator and wants to fight. There's no shyness or fear or anything like- it's really nothing I can describe.
There is a bright side. He's great with dogs that he's been raised with, very appropriate, and I've been able to introduce puppies with no problems. And very, very neutral dogs can be accepted over time. He's also 1000x times better in a show or trial situation, mostly because the other dogs there are so seasoned and comfortable around others that they totally ignore him. He's also been forced to behave himself in a show ring, so that's taught a little self-control.
His DA has made me better. I use better gear, I'm much more vigilant and will stand up and step into any situation to keep him and others safe. Both my dogs get more socialization, more training, and more attention because I am so conscientious that Rhys can't go to a dog park or hang out with friends.
