My dog throws up yellow foam & stomach gurgles after food switch. Is it normal?

I would recommend having Oliver examined by a vet. Vomiting in an older dog is always a little concerning for issues such as liver or kidney disease, pancreatitis, IBD, etc. Once he isn't vomiting any more, switching to a senior diet is a good idea.

A sudden diet change can cause digestive upset, especially if the switch was sudden. In most cases, a gradual switch is needed to help the body adjust to the new food. It would be best to pick up any food for a few hours, and then offer a bland meal of boiled chicken and rice to help settle Jack's stomach, then return to his old food. Once his tummy has settled down, you can then start transitioning to the new food over a period of 7-9 days (I would recommend only adding in one new food at a time, instead of both a new wet and dry food, to minimize upset). You can add in 25% new food to the mix every 2-3 days as long as he seems to handle eating the mix. If he continues vomiting, worsens, or switching back to the old diet doesn't improve his symptoms, then it is best to seek veterinary care to rule out any other underlying issues or illnesses that may be the cause of his vomiting.

Suddenly switching foods can cause digestive upset which can lead to vomiting. Not eating often enough can also lead to vomiting for the opposite reason -- not enough food in the stomach can cause a buildup of bile and acid which leads to digestive upset and vomiting. If you switched Finn's food too quickly, returning to his old food and gradually switching over a period of 7-9 days can help ease the transition. If he's not eating enough, offering several smaller meals throughout the day can help keep him eating (without it being too large of an amount at once) without his stomach emptying completely. If he continues to vomit even with the above adjustments, or other signs and symptoms appear, a full workup at your vet is best.

Hello. There any many things that could be going on with Elvis. He ciuld have something stuck in his stomach bouncing around that is intermittently causing a blockage and vomiting. An x ray or ultrasound would gelp determine this. Elvis could also have a food allergy so trying a different good could help. Try a good quality food. He could have a problem with his pancrease( inflammation or insufficiency), blood tests would show this, or he could have a motility disorder in which biopsies would be needed. If he is otherwise bright and happy and eating, try switching his food and avoid bones, raw food or table scraps and see of that works. If not or if Elvis seems sick otherwise then get xrays and bloodwork done with your vet. Good luck with him!

Switching foods too quickly can cause digestive upset such as vomiting and diarrhea. It would be best to return to Oli's original food until his stomach settles and then start a gradual change to the new food over a period of 7-9 days, slowly adding in more of the new food over time. This can help minimize stomach upset from the new food as he adjusts.

If your pet has vomited this much in the past 45 minutes I would be very suspicious of a foreign body or a very intense dietary indiscretion (eating something he shouldn't have). I would recommend you start supportive care (like Famotiidne 05-1.0mg/kg every 12 hrs and a bland diet like Purina EN Gastrointestinal canned food OR boiled plain chicken and rice or cottage cheese. However there is a big possibility that this could have been a toxicity and if any more symptoms start to arise (such as ataxia (staggering) or shaking, crying out) then I highly recommend you seek a personal veterinarian for a physical examination and further diagnostics. - Dr. H

Hi. Sounds like Millie has a pretty upset tummy. She may have gotten in to something, ate something new she isnt used to, she could have another type of GI illness, o4 something totally different. Unfortunately she would need to be seen and have some diagnostics done to guide us towards the most probable diagnosis and the correct treatment. Tonight i would hold off on food, and call your veterinarian in the morning
