I have a 3 year old dog that is believed to be having acid reflux. Her Vet did have her on Pepcid AC, but she was still having some issue's, so now she is on Prilosec. Here's the symptoms she was having: Acting like something was caught in her throat, gulping, licking her lips, burping, passing gas, not wanting to eat very much & then vomiting up yellow bile. (My dog is with me 24/7, & is NEVER out of my sight.
