My 7 year old boxer is having some excessive drooling episodes. For instance, she could be sitting next to me and I will look down and a puddle is on the floor under her. I saw on a different forum someones posted about the dog eating too fast and getting too much air in their stomach and to just help them burp. After I read that I laid her on the floor and rubbed her tummy and moved her back legs up and down and about 10 mins later her drooling stopped. This made me so happy and it worked a few more times, but now it wont work. Now she gets the excessive drooling a couple hours after she eats so I don't think it is air. The vet told us to use Prilosec because she might be experiencing heart burn but that only works some of the time. The drooling has been happening for about a year. She doesn't seem to be in pain, its just a little annoying. Does anyone have any similar experiences or advise?
