This will remain as a debate. But let me try to convince you why dogs are the more intelligent beings. Dogs have been domesticated for 16,000 years, maybe even 32,000 from recent search. While cats have only been domesticated for 10,000 or slightly more. Of course dogs are going to be all goofy since they have been domesticated for that long. Dogs still serve a great purpose in today's world. They help guide the blind and disabled. They have saved lives trapped in rubbles. Yes, even HOUSE dogs with no training, have saved lives. Like Buddy a GermanShepherd who rescued his owner from a burning house.
Small dogs also served a great purpose. An extinct breed of dog hunted rodents and spun wheels to generate electricity. They are extinct because we have (cats) more advanced technology. Dogs also helped us hunt and kept us warm during the stone ages. Not to mention they still do. Dogs are loyal and are social creatures, greeting you every time you walk in. Remember!
