If you are trying to prove that dogs have cleaner mouths than humans do you need to put your petri dishes in a specific place in order to grow your bacteria?

I did a science project on "Is a dog's mouth cleaner than a human's?" and it's not true. Even though our hypothesis stated that dog's mouths are cleaner because they have bacteria-cleaning enzymes in their saliva, it's not true. As to the question, you can pretty much put the petri dish anywhere, as long as it's not in the sun. That'll fry the bacteria. Cool places are best. Heat won't do you any good, but I wouldn't recommend you put it in the freezer. That's too cold. Just cool is what you want. Good luck. a dogs mouth is actually cleaner than a humans.......I've tested it myself!

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.....
