Updated On September 23rd, 2025

Pet's info: Dog | Siberian Husky | Male | unneutered | 3 months and 10 days old | 15 lbs

My puppy got into dog food bag and ate so much he got bloated. that same night he threw it up and cleared his system, but he began to throw up yellow after that. he drinks water but can’t seem to hold his food dow now. I am not sure what to do. He stopped throwing up for almost a full day until last night at 1:30am, he tossed up some more food I tried to give him. he doesn’t like pumpkin very much. his poop is normal and he’s not dehydrated but it’s hard for him to always drink water

Marley is probably suffering from gastritis and an over distention of his stomach from eating some much food all at once. The stomach lining is probably very irritated and is making him vomit up anything else he eats or drinks. I would recommend withholding food for about 12 to 24 hours. If he does not vomit during that time then you can start to re-introduce a bland diet, like plain boiled chicken and rice, and see if he can keep that down. If he is not able to stop vomiting, becomes lethargic, or has diarrhea you will need to take him to the vet to be examined. Small puppies like this can get dehydrated rapidly and he may need fluids support and medication to help stop the vomiting. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

    Marley needs to see a vet immediately. It's quite serious that she is vomiting so frequently for so long, and is getting worse. You are correct she could have eaten something in the garbage causing the vomiting, such as rotten food or something that could be obstructed in her GI tract. She needs veterinary care now. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

    Marley sounds VERY sick. There are many reasons ranging from toxins, to bacteria to intestinal blockage. She needs to go to the veterinarian ASAP (it sounds like she's hurting) for blood work and radiographs. Once the doctor knows whats going on, she will be able to help Marley feel better. I hope this helps!

My puppy Marley had a training class yesturday where the instructor feed him chicken and some hot dogs as treats. He was okay last night but this morning he woke up and threw up yellow. And just recently he threw up all of his food. I am not sure wha
Poor Marley! It could be the hot dog has upset his stomach, leading to the vomiting. I can give you a home remedy to try to see if that helps. Withhold food for 8 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. 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. Best of luck, I hope this helps!

Hello doc. My 5 months old puppy was vommiting for the third time at midnight. Her last vomit was kinda yellowish. I'm not sure what she had before, I think some unsalted crackers, wheat bread, and some cake. My dad gave her medicine for human diarrh
If a pet is vomiting, it is best to withhold all food and medicine for at least 12 hours. Afterwards, a bland diet can be offered in small, frequent amounts. It is never recommended to give human medications to your pet without the advice of your veterinarian. Some medications can be toxic or may complicate any underlying condition. If she can keep the water down, continue with small frequent amounts. No more than a couple tablespoons (20-30 mls) at a time. Have her examined by your veterinarian in the morning. The foods she ate can certainly cause vomiting, but it is best to have serious illness or foreign body ruled out by the vet.

Poor Gulliver! He could have an upset stomach from too many treats. If he is otherwise acting fine, you could withhold food for the day and then try a bland diet of boiled chicken and white rice and see how he does with that. If the vomiting continues or he becomes lethargic then he needs to be seen by your vet for treatment. Hope he feels better soon!

My pup isn't eating his food and he puked out everything he had last it was not watery but solid...
Hi, thanks for using Boop by Petco! Poor Mojo! Possible causes of vomiting and not eating are: intestinal parasites, foreign body (something is stuck requiring surgery), viral or bacterial infections, food allergy/intolerance, ate something gross that is upsetting his stomach, toxin ingestion, pancreatitis, kidney of liver failure and many other things. I would with hold water for 6 hrs and if there is no more vomiting offer small amounts of water and ice chips. Then in 12 hrs, if no vomiting, offer a bland diet of either boiled chicken or hamburger with rice as small frequent meals. Feed 1 cup per 20 pounds per day. If at anytime he vomits or won’t eat he should see your Vet. I hope this helps and I wish Mojo a speedy recovery!

Throwing up can be caused by a food sensitivity, dietary indiscretion, intestinal parasites, an intestinal blockage, bacterial infection, viral infection, the weather, food change, stress, etc.  I would fast Wes for 24 hours and then him 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 thevomiting or if the vomiting increases, or if your dog gets lethargic, he needs to see a veterinarian for an exam as there may be something more serious such as an infection going on.

Puppy just vomited it was yellow and he keeps sneezing. I've had him a week.
Yellow vomit is termed "bile" and this is seen when the pet has an empty upset stomach. Sneezing can also be a sign of mild allergies or nasal parasites (not as common). If J.R. continues to vomit for more than 12-24 hrs and also has other signs of sickness (i.e. lack of energy, not holding down any food, lack of appetite), then it is best to get J.R. seen by your veterinarian for strong medical treatment and good physical exam. However if J.R. is still relatively active, happy and playful, you can try withholding food for 12-24 hrs then feeding him a bland diet of plain boiled chicken and rice or cottage cheese OR Purina EN Gastrointestinal. Hopefully this is enough to settle his stomach and get him back to normal.

my friends dog has been throwing up yellow refused to eat and refused to move much do u know what that could be
Poor Bo! This sounds really serious. There is a good chance he could be suffering from parvo virus, a Gi foreign body or severe parasites or something else. Since he is so young and seems to be really sick, I strongly recommend to have your vet take a look at him. The vet will be able to test him for parasites and parvo. They will also be able to blood work and x-rays if needed. They will be able to get him on a treatment plan that will help him feel better. I hope this helps!

No, I wouldn't make either of them vomit. Keep an eye on the puppy for now, and I can give you a home remedy for Elke to see if that helps.
