All of my dogs are female. That was not intended, it's just how things ended up. We have 3 dogs, 2 of which are mini dachshunds. My Corgi Grace has been fighting with the oldest dachshund, Ziggie, who is 11 years old. When I got Grace, the breeder told me that she would try to test her dominance and to make sure I feed her last and to put her in a "time out" if she growls or snarls at the other dogs. We have been doing this from the start and it hasn't made much of a difference. In fact it's getting worse. For example, yesterday Grace and Ziggie got into 3 fights.
Usually they fight once every couple of days or sometimes we can go a whole week without a fight. Whenever they fight Grace starts it 90% of the time. Ziggie will be walking around the house minding her own business and Grace will run across the room and start the fight. There is no rhyme or reason except for when Grace is in my room, which is kind of her kingdom. We've noticed when the other dogs go in my room Grace sometimes snarls at them to get out.
So back to yesterday. One of the fights was in our living room. Grace ran across the room to get her. Then in the backyard they got into a full on fight. I happened to be outside by them with a running hose, so I hosed them down. That worked. Then later on in the evening Grace was in my room and Ziggie was in there hanging out. Everything was fine. Then out of nowhere Grace attacked Zig. It looked like something off of Discovery Channel. I separated them and put Grace in her kennel for a time out. Ziggie has a scratch on her eye, a tooth hole next to her eye, a hole in her ear and a bite mark on her nose. It was bad this time.
We've tried the feeding last thing and the kenneling thing and the tethering thing. Is there anything else we can do to stop this?
