I think dogs have the potential to be more enjoyable because they're smarter and more trainable than cats, but I'm more of a cat person. I would pick dogs if I was wealthy or living with someone to share the responsibility of taking care of the dog. I'm accustomed to doing the things that I have to do take care of my cat (feeding, grooming, cleaning the litter box), but dogs are more expensive and time consuming. I don't think I could ever get used to doing the extra things that I would have to do with a dog without some kind of assistance. And some dogs also have separation anxiety. There are some cats that demand attention and physical contact when you're around them, but a cat can never do the amount of damage that an anxious or bored dog could do when you're away at work.
