Donna, come on out of the 'doghouse' I'm sure you were very upset when you posted that. Of course it was not the dogs fault, it was the owner, who obviously did not love her cats. I edited my post in that thread.
We recently adopted a puppy instead of rescuing an older dog because we felt it was safer for our cats. If a new dog went after my cats, it would have to go back or be rehomed, because they were here first. We just felt safer with raising the puppy with the cats.
