I'd be curious about the pedigree also.
this doesn't sound good "I contacted the breeder and she said she can't take him back, she has too many puppies"
what did the dog display until that "two months ago" when in the public and dealing with people? What changed.
Seems like you've run the gamut of what is generally recommended, a trainer, a behavioural specialist, another trainer who called upon another for an opinion.
If one of them concluded that he is wired for high prey , then did the dog show you this while he was in your home. Did you play ball with him.
One comment was that he was wired for high prey and so cannot be in a home with more than one person . There are many, many , high prey dogs living wonderfully in active big family homes and high social contact .
I don't think a police department would take on a dog that has already had so many wrongful bites. The dog still has to be social . His usefulness would be severely limited .
If the dog is medically well , he may be able to be placed in some high security use , one handler . Even there the dog would have to meet hip clearances .
Keep a record of where the dog has been while not in your care, in case you have some sort of litigation from "the jogger" that he bit and drew blood on. The trainer that he bit sort of expects stuff like this as part of his work .
curious to see the outcome .
Honestly, I am not even sure I completely understand what high prey drive really means. He is completely obsessed with playing catch. And I mean obsessed. When there is a tennis ball around, he will not focus on anything else. He would play ball all day long if we let him.
The strange thing is, is that he would seem to calm down for a bit once someone new was over but then something would always set him off and he'd go into lunging, crazy barking mode. It got to the point where we were basically prisoners in our own home. We couldn't take him any where and couldn't have any one over. That's not fair to him and to our 2 young kids that couldn't have their friends over. I was terrified something would happen to a child which left my husband and I constantly on guard.
We are very lucky the jogger didn't come after us, well not yet any way. I honestly don't think I would have been as nice about it as he was! I would never, ever forgive myself if something happened to any one else so for that reason, he will not come back into our home.
The trainer said he could not be in a family home because it is his determination that he can only be attached to one person. He said it in a more formal way, I'm just so sad and overwhelmed that I can't remember exactly how he worded it. I'm taking his word for it though and will not even consider trying to place him in a family setting.
I will keep track of where he has been, thank you for that advice.
