Who has more bacteria a dog's mouth or people's mouth?

A dog has more bacteria due to the things it eats, chases after and who knows what else it did?? I tested this for a science project one year. I used petri dishes and swabbed 3 dog's mouths and 3 humans' mouths. I found that more bacteria grew in the humans petri dish. Good to know that we take better care of ourselves then dogs.....
