My English bulldog will be 9 in November and up to this point he has been in great health, now over the last 9 months he has had an issue about 3 times where he drools excessively and if I go try wiping the drool he yelps like I'm beating him. And if I just try comforting him by rubbing his head or ears he yelps more. I take him to banfield hospital and pay a monthly fee bc God knows English bulldogs are expensive. Anyways this is really concerning but when I take him into the hospital he hates them to touch him. He is seriously a big baby with everyone who walks in my house but there he just gets so angry. Has anyone had this issue before? Why is he yelping when I run different spots on him? Would having a tumor cause him to yelp when being touched? Or could he just have a tummy ache and doesn't want to be bothered? Any help would be appreciated.
