My dog is throwing up and slow after new food. What should I do?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 12 years old | 25 lbs

My dog has vomited several times today (sometimes chunky, sometimes bile) and is moving very slowly. When I tried to call her over, she would not come and I had to prod her to move, whereas usually she is very responsive. We gave her a different type of food yesterday because we ran out of her usual type -- is this the likely cause, or might something more serious be going on?

A change in diet can certainly be a cause of vomiting, and since Sunshine had a new food recently, that may the reason behind her vomiting. I can give you a home remedy to try to see if that helps. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the vomiting continues in the absence of food, she vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away. Best of luck, I hope this helps!

My dog weighs 65 pounds he is a 6 year old mutt. Lately he has moved from ole roy food to retriever brand food. Today was the first day he was fully weaned. He hasn't eaten any of his new food in about 3 hours. He woke up and threw up on the carpet.
It could be due to the new food. I can give you a home remedy for Chance to se if that helps. Withhold food tonight, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he refuses to eat the bland diet, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away.

I got a dog friday and he ate some food saturday and now he is throwing up do you know what it could be?
I'm sorry that new dog is sick! The food that Loki ate on Saturday could be causing his vomiting. He could also have a GI illness, foreign body, or pancreatitis. I can give you a home remedy to try to see if that helps with his vomiting before having to take him into the vet. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in Loki's normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away.

My dog just threw up like this, what could it be? He has never thrown up like this. He had not eaten anything, yesterday i got him new treats, and earlier today i gave him a few kibbles duck flavor as treats that he has never had before.
Poor Iker! It could be the new treats you gave him causing the vomiting. A sudden change in diet such as new treats can causing GI upset. I can give you a home remedy for him to see if that helps. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet.

I picked up my dog 2 days ago from obidience school, she started throwing up today. They didn’t give me any food & I don’t know if the food I got her is causing this or what.
She might have eaten something spoiled that is causing this. withhold food for 12 hours then offer her boiled boneless chicken and rice every 6 hours in small portions. if she is eating and not vomiting, continue with this diet for 2 days. After 2 days, you can put her back gradually on her normal food. If she continues vomiting or is not eating, take her to the vet to get treatment.

My mom has a 10 year old pom/poo that is having stomach issues. She has been throwing up. She refuses to eat dry dog food and we have been giving her the same dog food she usually eats. Do you suggest some medication we can add to her food?
Throwing up can have many causes such as a problem with the stomach and intestines caused by a food over sensitivity, eating something that does not agree with the dog, intestinal parasites, an intestinal blockage, bacterial infection, viral infection, the weather, food change, stress, etc.  I would fast Misty for 24 hours and then put the dog on bland food for two days, such as boiled white rice and boiled white boneless chicken meat, fed in small quantities over several feeds and then transition back to regular food slowly over a few days. If this does not clear up the vomiting or if the vomiting increases, or if your dog gets lethargic, it needs to see a veterinarian for an exam as there may be something more serious such as an infection going on.
