its a way of saying hello
Friendly gesture
Dogs Like/sniff other dog butts to get information about the dog. It is a form of communitcating.
If dogs do not lick you then they do not appriciate you. Dogs lick you when you give them a treat or play with them.
if yours does, that's just weird
it is a way of saying hello if the other dog won't let the dog sniff him or her it is because he or she thinks of that dog as an intruder
They may be cleaning a wound or just doing it because they like the other dog.
Your dog is not going to get sick from licking a cat's butt. Animals are always licking their butts.
I would not mix him with other dogs, you can't tell where the other dogs have been or if they have had their shots. Dogs will sniff or lick feces etc. Get the shots.
It's a possession thing. Dogs' saliva has a scent just like their urine...each is recognizeable. They will usually do it when there are other animals present in the house, but not always. They are claiming that person as "theirs".
dogs heal your wounds
Dogs usually lick other dogs lips because its a way that the dog is nurturing the other one. It is just something they do to mother eachother. My dogs do it ALL the time and ii think its really cute and sweet to watch.and from when dogs were wolfs, the younger lickd ther parents mouths for food. Answer: Dogs lick each others mouths as a sign of submission and respect. Their saying,'You're the boss.'
Why does my 15 yr old dog lick blankets
