Yes, pets are cute and it's important to love them and take care of them, but your dog is not your baby!
Dogs go outside for, among other things, exercise. Dogs can walk. Babies cannot, that's why they get pushed around in strollers. Hey douche, chances are your dog can (and wants to) walk- take it out of the damn baby stroller and let it.
I support a dog in a raincoat. It keeps the dog from getting wet, but most outfits aren't practical and are silly and some are just plain mean. Stop dressing up your dog. Dogs are not babies!
