My bulldog keeps shakeing his jaw and lots of water coming out of his mouth often two to three times a day I have taken him to the vets and the have given him a clean bill of health can anyone give me advise on what could be causeing this problem a

I have a English Bulldog, and when he was younger, he would shake from time to time, although no water would come out of his mouth as a result and it was only for a minute or two.

He's stopped shaking since, and no one was able to determine what it was, I personally thought it was growing pains as he was young and still growing.

If your dogs young, it could be that, but if not, I don't have much else to tell you

Did the vet check his ears? And check in his mouth as something could have become lodged.
Is it only after he drinks?
