I've always been more of a dog person, before I even had a dog I liked dogs more. From my experiences, all the dogs I've ever been around have been much more friendly than cats are. My dog will lay with me for hours and if I'm upset or in a bad mood my dog knows and he'll come and sit with me. I feel like dogs are just more human-like than cats are, if that makes any sense. Cats seem to like to be alone more and I just don't like that, I love caring for my dog and brushing him and walking him and napping with him but I've never really met a cat that would rather spend time with its owner rather than alone. But that's just my experience with cats, I'm sure there are plenty out there who are more inclined to not sit alone all day
