I have 4 dogs. I found a Saint Bernard 5 months ago, who was running loose and have taken him in, had him neutered and vaccinated. Initially the alpha Chessie made it clear he was the boss and the Saint wouldn't even fight back. Sometime in the last month or two......the Saint began challenging that position. He is estimated to be about 1 1/2 years and the Chessie is a little over 2. Initially, it was low grumbles from the Saint, who got time outs for such behavior. The Saint also displayed some aggression toward the people if we wanted him to do (or not do)something against his will. He would nip, without breaking the skin, if we pulled on his collar, for example, to get out of a vehicle when he didn't want to. I thought he just needed someone to put him in his place. I've watched Ceasar and for some crazy reason, we thought my husband could "break him down," which I now understand to have likely complicated his problems.
So I spoke with a trainer and we seemed to be making some progress with the dominance issues versus the people in the house. But, 3 weeks ago, the fighting between the two dogs got incredibly worse and they went at each other with everything they had, leaving me to try to break it up, which I did inappropriately and got bit. This was significant enough to visit the ER and require 4 or so days off work with a nonfunctional arm. Neither of them was hurt enough to go to the vet, but had knicks, which we cleaned up and treated at home.
We have kept them separated since. I have tried to rehome the Saint, thinking an environment with less dogs and an experienced owner would be the best, though heartbreaking, choice. All rescues are full and some won't even consider him because he now has a documented bite.
Today, my husband decided to take the two for a walk together....try to get them to get over it. (NOt a wise decision alone) Initially, he said they did well and then all of a sudden the Saint started grumbling and the fight started. He had to separate them, which again, was extremely difficult.
I have read what I can get my hands on. I am currently reading the Secrets to Dog Training. I understand we need to further establish ourselves as the alphas and how to do so. I do not know how to proceed with these two dogs. I do not want to put the Saint down, but cannot seem to work out how to make this situation work. I will not drop him at a shelter, as that would be a death mission after a few days of extreme fear for him.
I need specific help and quick. I also fear the instability in the house's effect on the rest of the dogs. Currently the Saint is in a finished basement room with access to a fenced area away that is inaccessible to the other areas of our yard. We do put the other dogs with both the ones that fight without any significant issues; all the dogs are altered.
Any suggestions or ideas would be greatly appreciated! Thanks so much.
