lip quivering
 

I have noticed a few times that my puppies bottom lip will quiver for just a few minutes. It looks so cute. He can be playing and look up at me and lip will quiver:animal36 Has yours every done that?

That is so cute! When I tell Roxie to sit and stay and have a treat in my hand her bottom lip will quiver.

My girl used to do that whenever she got a good chew of the cat or just finished servicing the cat's behind. It even happened after she had only pounced and chewed on the cat's ear for seconds. It really depends if she got the chance to get really into it.

Now, I had addressed this concern with each of the vets I had visited with before I had settled on one. The general consensus was that it was alright as she was just showing her excitement. But if I recall correctly, one of the vets said I should try to keep that to a minimal. At first I was concerned that she was getting too "worked up" over chewing the cat, and concerned, like little children who get too tense and end up pinching hard, well, I did my part in stopping the play when it looked like it was getting too rough and she'd undoubtedly come out of it with quivering lips. I was also worried her little heart might not be able to handle all that excitement her quivering lips would indicate she's experiencing. :p

She seems to have grown out of it now. I haven't noticed her lips quiver even once for months (she's a couple months over a year old) in spite of more lengthier and involving romps with the cat. They're both female, by the way. :p

i hate to reopen an old thread but better than starting a new one
my dog quivers his bottom lip every time he opens his mouth
if he yawns when he closes his mouth hell quiver his bottom lip i dont know why

I have only seen my boy do this when I have a girl in heat. :)

;) Yeah, Huckleberry will do this when Livi is in heat...but Livi has also done it when she is excited over a treat.

he does it even when hes extremely tired and yawning i thought maybe a tooth is about to fall out
