My english bulldog keeps on gagging and making chocking noises as if he were about to throw up for a couple of months. He had two seizures two or three months ago, and we took him to the vet, but he hasn't had any, as far as i know, since then. He's also developed this weird balding that is very flaky and i thought might be flank alopecia. Do any of these things correlate. I just reframe from taking him to the vet again because they always deemed every test inconclusive and i just don't have the money to take him back without getting any real answers.
