dog's mouths have less bacteria than human so it's ok. question: do i need a possessive apostrophe in the word mouths above?
No. The mouths don't possess anything - they're what's being possessed. However, you've got the apostrophe in the wrong place on dog's (unless you're talking about 1 dog with several mouths). 1 dog's mouth several dogs' mouths
