I only really want ONE dog. Well, "I" don't want one dog, but my work, lifestyle and boyfriend choices made the decision for me.
Even that might be difficult, my OH and I like completely different kinds of dogs for completely different reasons...it's making it difficult to choose a dog/breed that will work for both of us.
I've had my fair share of rats, mice, hamsters, guinea pigs, ferrets, fish, geckos....I have no desire to own them again.
Cats...I'm on the fence, I love them, always had multiple, but don't really need to have one in the future.
