So you haven't had a problem since August? Until last night? If that is correct, then what you're doing is working. This is a problem that will never be 'fixed', but controlled. With you trying to breed, new circumstances (hormones, smells, etc) will always be coming into play, and adjustments will have to be made in how these dogs are handled to control the problem. The fact that the one dog may be pregnant (probably is) would be enough with the hormonal changes alone to trigger the attacker's behavior. Steps need to be put in place to prevent them from harming each other.
That said... IMHO, if you're going to be breeding, focus on that goal and do everything that is neccessary to provide a calm, safe and successful breeding/whelping environment for those dogs. Some dogs can live peacefully in a breeding environment, some cannot. So for safety's sake, rehoming is the wisest choice in this situation.
The fact that one bit you does not mean failure, it's a slip up. My male bites at me all the time when he's asleep and I get too close. He always wakes thinking someone is after him. So when I need to approach him, I start by talking to him, and when I first reach for him, I go to touch his butt, so he has a chance to get his wits about him and realize it's me and not another dog. If he still goes after my hand, I have enough space and time to get out of his way, and give him a bit more time to fully awaken.
I don't think there's any dog, show, pet, agility, whatever that does right 100% of the time on everything. I think it's unrealistic to expect that from any dog. Strive towards it, yes... |
