My brother really doesn't like animals. He likes to look at them at AK, but won't touch them. Cats are the exception, though he doesn't seek out our cat. Every once in a while I make them interact. He will pet her, but just generally finds animals too unpredictable to be around. Dogs for him are especially unpredictable for him. But he's okay with strange cats. He's not like me in that I try my best to make friends with cats, but he can pet them and calmly be around them.
I like little dogs. My bff had a sweet little dog named Mini. Mini never hurt a fly. When they got her as a puppy, it was funny when she would get out because her mom would have to chase this little dog around the yard. Oh boy was that fun to watch. But Mini settled down eventually. She passed away a few months ago unfortunately. My bff's aunt had a dog, Wattie, that was a mixture of pug and sharpei. That dog was funny because bff's aunt was living with bff's grandparents at the time, and when we would go swimming, Wattie always lifeguarded the pool. She was a fun dog.
Unless I marry a dog person, I can't really see myself ever getting a dog. As long as I have Belle, I can't get a dog; she's terrified of them. But if I were married to a dog person, we'd have to compromise and get a little dog. The right little dog that is. But also, we'd still have cats.
