My husband & I rescued a 2 year old terrior mix, female. She appears to be part Jack Russell terrior & fox terrior, is very pretty, sweet and obedient for the most part. We have 2 other dogs, both spayed females as her and they were getting along fabulously after only 10 days. However, we also have 2 cats, and she is cat aggressive. Both cats have access to our basement where the dogs cannot get through to them but the cats have always come upstairs with the rest of the "family" as they pleased. With this dog here for 3 weeks now, the one cat will come upstairs if I hold the dog and she hides behind the furniture then. The other cat, a neutered male and usually one that plays with the dogs a bit, is afraid and will not come upstairs at all. This dog is very sensitive and very much wants to do what we request, but she has a difficult time not running after or barking at the cats. How can I train her to leave the cats alone? Any suggestions?

It might sound cruel, but it works. Spray the dog with a water bottle when it bothers the cat. The water won't hurt the dog, but they sure don't like it.

Thanks! The water spraying sounds like a great idea. I used that to train my cats to stay off of the dining table & cabinets. I'll try this with the dog.
