My dog is throwing up and drooling. Is it from a sudden food change?

Updated On September 23rd, 2025

Pet's info: Dog | Siberian Husky | Male | unneutered | 3 years and 7 months old | 62 lbs

My husky, Jack, has thrown up a few times this morning and is drooling a lot, clearly doesn't feel great. Yesterday I added some wet food into his regular morning meal and added a new dry food to his regular food for his evening meal (he picked around and only ate the new food). Is this why his tummy is upset? I just wanted to see him eat well because he stopped liking his regular food

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.
