Contact a GSP-specific rescue group. Do not kill a dog for being a dog, without giving it the grace of having a chance at a better situation. The last 2 Vizslas we fostered were surrendered to our rescue for aggression (biting). Both had some behavioral work to do in foster care, which took 2-3 months as only dogs in the house. Both are now with owners who understand them, dogs and new owners are living the dream together.He'd already be in the ground if he was mine. I'm zero tolerance for biting.. No excuses.. Just the liability aspect of a dog who has bitten is enough for me to not want it. Being that he is a known bite risk if he bit anyone else you would be in deep dodo knowing before hand..
Not to mention dogs are not people. If he will bite you when threatened and you say he's bonded to you what would stop him from biting a stranger..
I'm pretty sure I will catch flack for this but I've seen dogs do some pretty terrible things to kids. Of course the owners made excuses but almost every time when all things were revealed it came out that the dog had bitten people before..
I'm not going to say I'm sorry for how I stand on this one. Put it down..
Almost without exception, dogs aren't the problem, people are. Fullquiver, fish make good pets for people that don't understand dogs. Dogs that "do some pretty terrible things to kids" were made that way by the 'humans' that were supposed to care for them.
