bro im glad that your a nurse. and no their mouths are not cleaner then humans and once again prove that to me with any study you can find. you being a nurse in no way makes you a scientist. my sister is a nurse and my wife is studying to be one. ill ask my sister how she fels about that. but for now this is the last post i will make on the subject. i think that we can agree to disagree. but i will give you the fact that you have more education then i do on the matter because i dont have any medical schooling what so ever. but like i said to you earlier i searched high and low for any such study and i could find none. all i could find is that there would be almost no way for a dogs mouth to be cleaner then a humans. i may if i have time post some findings for you in the other chat forum but not in here. ill let you know if i do. it just depends on time. im buisy right now with the end of the semester. but for now no more post from me in here on the subject
