My Dallas is having problems with that also. He has had test to see if its any else . Came back normal. Still get worried and hope it won't lead to anything serious. He is on Royal Canin Hydrolyzed Dry , pepcid, probiotic. Still throws up not as often did today.
I just wish it would stop completely. Vet says he has sensitive tummy and as long as its not as often as before. I an still worried. After he runs around and is fine . If anyone finds anymore info let me know. Hope all your babies stay healthy.
