I had the same problem with a female I had. It began suddenly after co-existing fine together for about 5 or 6 months; then BAM, sudden, seemingly unprovoked vicious attacks towards my younger female. I tried everything I could think of to no avail. For the other dogs safety and our sanity we ended up re-homing the one that was being agressive. It was VERY difficult to do, but definitely necessary. She is now very happy living as top dog in a one dog family. |
