My golden is 5 years old and we’ve noticed that she’s been regurgitating quite often. She had allergic reaction to chicken so we switched her to salmon. After switching to salmon she started having regurgitating once in a while and she’s been having salmon for 5 months now. Still regurgitating intermittently (one week she regurgitates and fine for another 2 - 3 weeks then regurgitates again) so we thought maybe it’s the salmon as that’s what started it and now she’s on lamb. 5 days into half salmon half lamb diet she regurgitates again. She’s acting normal, playing everyday, eating a lot, good appetite, poops normally and all. We’re running out of ideas as to why. Previous owner mentioned that she has a weak stomach and can’t have other food aside from chicken because she throws up and now she’s allergic to it. What to do? Bringing her to the vet would mean blood tests and all but we want to resolve it on our own if it’s just her diet or habit issues.
