Yea, well, it depends on the dog to.... One is not going to get a lot of hunting out of a chihuahua.... How-some-ever,,,, we more often than not see Paris Hilton caring one those rat wanna-bees around in her purse!
I used to be a cat person, but this current crop of cats (3) has been rather destructive, as a result, I have developed a strong diastase for cats.
The dogs on the other hand (2 chiweenies, a chihuahua, a wiener dog, and a Pomeranian) love to love, and mind very well. I've become a small dog fan.
