Marissa, your dog sounds kind of like mine. I have done years of training, and spent a lot of time working with professionals in order to stop her dog aggression. I to got her with the hopes of having a service type dog to take everywhere, and the aggression really makes that difficult. It is a very difficult behavior to stop, but focus only on the progress you've made, and realize that you are doing the best possible thing by helping train the dog.
I don't think my dog will ever be the type of dog that can be taken to a dog park off leash, but I love everything about her, and couldn't be happier with her. She also teaches herself tricks, opening the doors, fridge, etc... And she is super intelligent when it comes to training as well.
Small Bullies, it sounds like you love your dogs, and I meant no offense in my post. I just see Pit Bulls with cropped ears, large chains, etc... And understand this is the reasoning behind public fear. Some people name their dogs to sound intimidating, or actually go out of their way to encourage aggression as a symbol of their own status. For me, owning a German Shepherd with dog aggression, I don't see how people are proud of it (not that you are). I have spent endless hours and resources trying to curb those behavior problems, and for people to try to create those problems is beyond me. I don't have to talk my GSD up to look tough, I don't feel the need, and would rather people see her for the sweet dog she is.
Sad video Nanci, I think Vick has served his time, but that won't ever change my disgust in him. I saw this show called DogTown, and they helped some of the Vick dogs. They seemed like sweet dogs too, it is so sad that people didn't encourage their natural well behaved temperament.
