Dog licking baby, is it safe?
It probably is, but keep in mind that if your child has any open wound the dog should not be licking in that area at all. They have bacteria in their mouth that can cause a wound to become infected.
Of course it is a personal preference if you even want your dog to lick your baby. I am firmly in the no category on that one even though I know they just do it to show affection. They also like to eat animal poop.
