I have two yorkies that we feed the Royal Canin yorkie breed food. They often hack up a yellow foamy vomit (not a daily problem but close). Our vet has said that they probably have acid reflux and to try giving them a bit of pecid ac to reduce acid. Has anyone ever tried this? Or had a similar problem? We have considered switching foods but often hear that RC is the best so are reluctant to switch. Any suggestions for other foods or does it not sound like a food related problem? Thanks
