I love both! But if you're thinking about having a dog, you got to make sure you have a good schedule for them. They need to be walked outside quite often, and can't be left alone for too long.
Cats ! I got bitten by a greyhound not too long ago ,had to get a tetanus shot because of it,then had an allergic reaction to the shot. It's left me terrified of dogs now unfortunately��
As much as I love dogs, I'd definitely say cats. My kitty currently has a cold and keeps sneezing:c but I love how laid back cats can be and how he just sits by me when I'm working and doesn't bother me.
