I have both; a 10yr old Calico cat that is about 25lbs. A 20lb White American Eskimo and my son's dog which is a very large 7yr old Akita. Each one brings thier own joy and frustration to the mix; just like kids do. I can't say that I have a favorite breed of dog but I do have some that I'd never own but since that is my personal opinion I won't mention what they are. My favorite pets that I've had in the past are: a German Shepherd, a Laso Apso and a Pekingnese. I live alone now for the first time in over 40 yrs and having the animals there when I get home is great because not only do I feel safer coming into an empty house with the dogs there they are also company.
