Introducing "aggressive dogs"

[anarchir]

I have had experience with owning two dogs who didnt get along before. The only thing was, they almost always got along except for the rare occasion when the dominate one would just snap and attack the smaller one. Sent her to the hospital twice. We had to keep them always separate after that. One in the house and one in the garage, etc. I have also had to send a dog away to live with my parents because it couldnt handle my living conditions (apartment living for a border collie). If you truly want the best for your dogs you wont put one that attacks dogs with another dog IMO. Sooner or later...
