I'm the mom to Bugs, a 1.5 year old american pit bull terrier. Over the past month, he has been having what seems to be GERD. He has regurgitated his food, but only twice in the past month. He wakes up early in the morning swallowing and licking his lips, and then throws up bile. Our vet thinks it is related to his allergic skin disease, and put him on apoquel short term to reduce inflammation, and cerenia for four days. Any tips on how to not just mask the symptoms, but to resolve them with diet and natural remedies?
