This is a tough question for me too.
Cats: Not THE biggest fan but there are a couple of breeds I like:
- American Shorthair (black)
- Pixie Bob
Dogs: I LOVE the huge, powerful breeds. The bigger, the better to me. They are awesome to work with and depending on the breed, can be a challenge to train, which I like.
- Pit Bull
- Bully Kutta (aka Pakistani Mastiff)
- Presa Canario
- Czech Wolfdog
- American Bully: I love how these look like stumpy pit bulls LOL
I also think the Maltese and some Shih Tzus are really cute too. ^_^
