My dog threw up after puppy food switch and now won't eat. What to do?

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.

I recommend bringing Duke to the veterinarian. There are many viruses and other things that can cause these symptoms. Your veterinarian will be able to determine what is going on with Duke and treat him. Thank you for using Petco Pet Education Center, formerly Petcoach.

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.

It sounds as Bany is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking her to the vet the first chance you get, she will need to be checked first, if the vet thinks it's a simple gastrointestinal infection she will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better. if the vet thinks it is more serious she will need a blood test and possibly an ultrasound in order to find out what is wrong.

Chronic vomiting, has multiple causes but may cause an electrolyte imbalance which could account for the symptoms you are seeing. If he is drinking more water than usual, he should be seen by your vet for an exam and bloodwork to rule out kidney disease, diabetes or other GI issues. When a pet is vomiting, withhold food for 12-24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet (1:1 ratio of plain boiled boneless chicken and plain white rice). Feed in small, frequent amounts waiting at least one hour between feedings. If he won't eat, serve the food warm or mix in a teaspoon of baby food to stimulate the appetite. If the vomiting stops, transition slowly to the regular diet. If not or if the appetite does not return, then you will need to see your veterinarian.

Since both Buster and your pug experienced vomiting after the diet change, it stands to reason that the new diet may be associated with this issue. However, Buster’s ingestion of Mobic (meloxicam) could also be associated with his GI upset. Overdoses of meloxicam can also cause kidney damage, which can also result in lethargy and vomiting. Since Buster is still lethargic, it would be best to take him to his vet for an exam and blood work to check his kidney values. If his vomiting continues, he will also likely need abdominal xrays to determine if an intestinal obstruction is present due to the toy that he ate. After any possible medical issues have been addressed, it may be best to avoid using this particular diet. Just remember that anytime you change a dog’s diet to do so gradually by mixing the foods together over 5-7 days. I hope this helps and that all goes well!

It sounds like Nestle is pretty sick, but unfortunately vomiting can be a sign of a number of different diseases. I’d recommend having Nestle examined by a veterinarian today. This could be a sign of diseases like pancreatitis or kidney disease, or even a partial intestinal obstruction. If she continues to vomit she will probably become dehydrated.
