Lexy has been doing this for some time, for no reason just start licking lips and drooling excessive. Trying to figure out what she doing or eating at time but I have no clue. Found growth on her gums and it was removed and thought that was reason but still she drools. Vet thinks cause she such nervous dog it's anxiety but there is nothing to be upsetting her and she has this episode. I don't think she is bloating. Anyone else have anything similar? I hate seeing her like this and I can tell she don't feel we'll. help!!
