I have done all that I could find to help my dog, a 2yo pitbull boxer mix, but I am not seeing any progress.
He that has a crate he stays in sometimes (at night/when I cant watch him/when little dog is out but i'll get to that later).
I do feed him in the crate (to reinforce that the crate isn't a punishment because he used to hate the crate,, he likes it now.. also, he's food aggressive), but even when he doesn't have food in there he still barks, growls, and lunges at our other dogs and even our cat if they get too close. This is only when he's locked in the crate.
Out of the crate (food aside,) he does just fine with the other animals (another big dog and a cat) except for a small dog, but that's irrelevant at the moment. He's not aggressive with people.
I've tried positive reinforcement with both affection and food when he does good with other animals near the crate [when he's locked in], but it all ends up with him getting upset and trying to lunge at the other animals.
It seems that no matter the food or how I praise him, he doesn't care when it comes to getting other animals away from him when in the crate. I'm really at a loss for what to do.
As for him and the little dog, I have just been keeping them seperated.
The little dog is my older sisters dog (a very yappy and annoying dog that likes to annoy other animals and act like hes boss,) but she lives on a seperate floor from us so they dont cross paths save for when little dog has to go outside or when theyre on the same floor as us watching tv or something.
My dog has a high chase and prey drive. The little dog is small and immediately runs from him, trying to play. See where things don't work?
Theres been a couple instances where they have had run ins (not anyones fault, just accidents or his drive takes control of him) where my dog has chased the little dog. We don't know if he's chasing to play, or chasing to kill. (he has killed rats and birds, so we know he's more than capable of killing). My family truly thinks he's trying to kill the small dog, and even though I think so too, theres a small part in me that thinks hes trying to play (he really doesnt know his size… and he sometimes chases the cat like that and I really really do think he wouldn't hurt her on purpose, i've never let it go on long enough to find out).
Every one of those times, we have tried to get him to stop by calling him, shaking treats, and my family has even protected the little dog with their bodies. Each time, it's like he loses control and can't even stop himself. Many of those times, i've had to jump and lay on him to give my family a chance to get the little dog to safety. I am a 5' girl, and he is nearly as big as me. Even though I am strong for my size, it's a struggle for me to have to fight him like that, and some times he's even left me with bruises. I know he would never hurt me on purpose. My heart breaks a little more each time.
This is my best friend, but my family wants to get rid of him. These things aren't the only things he struggles with, just the main ones. I love him, but he needs help that I haven't been able to give him. I really don't know what to do anymore. Affection doesn't work, treats don't work,, not even high quality ones or even human food.
Please help me help him.
