My dog has had an upset stomach for 72 hours, not eating or drinking much accompanied by being sick. Is it best to fast him or still offer small portions of chicken?

Poor Louie! I'm sorry to hear that he's sick. My general rule of thumb with vomiting and not eating much is that if it goes on for more than 24 hours, a vet visit is warranted. So if this has been going on for three days now, I would really recommend having him seen by a veterinarian today rather than continuing to try and manage at home, since I would be concerned that he has something more serious going on than a simple upset stomach.

If you're not able to get him in to an emergency clinic today, then it's probably best to continue offering small amounts of something bland such as plain boiled chicken every few hours until you are able to see the vet. But I would focus on finding a way to have him seen as soon as possible.

I worry more about the fact that he can’t get comfortable than I do about the vomiting. He’s a large dog and won’t get as dehydrated as quickly as a small breed. A small amount of turkey I wouldn’t expect to make him so sick, but some dogs are more sensitive than others. Other possibilities include pancreatitis and intestinal foreign object obstruction. I agree with a veterinary exam tomorrow, but it certainly would not be wrong to have him seen tonight. If nothing else they could at least give him an anti nausea injection (my favorite is cerenia) to make him more comfortable. I would definitely fast him tonight though. No food at all, and small amounts of water at a time so he doesn’t gorge and the vomit the water. Best of luck and I hope he improves soon. Thank you for using Pet Coach.

My dog is vomiting, has diarrhea, and won't eat for days. Vet needed?

Hi there. Dogs can certainly get a minor upset stomach due to an infection or something they ate, but this should normally resolve within 24 hours. Since Brutus has been sick for three days now, I would definitely recommend having him seen, as this may be a more serious problem. He may have a GI problem such as pancreatitis or a foreign body in his intestines, a systemic illness like liver or kidney disease, or may have ingested something toxic. Your veterinarian can do blood work and x-rays if needed to help diagnose the problem and get him started on appropriate treatment.

My dog's stomach is rumbling with loose stool. What should I do?

Poor Charlie! Feed him a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the loose stool continues on the bland diet, he starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. Best of luck.

My dog had a stomach ache. When can he eat again and what food?

There is not a hard and fast rule for how long a pet should be without food. Some vets say as long as 24 hours. I generally recommend 6 to 12 hours. It may help also if you feed him a bland diet for the next 24 hours. Boiled white meat chicken and plain boiled white rice. If he continues to be sick, have him examined by the veterinarian.

My dog is trying to vomit and retching. What should I do now?

Hello, I am so sorry for your concerns about Louis vomiting. If he is continuing to vomit, or is continuously retching, then yes, he should be seen by his veterinarian. But if he is quiet, then you can rest his stomach for about 12 hours. Then introduce a bland diet of 25% boiled, skinless chicken & 75% boiled white rice. If Louis is hungry, only give him a tablespoon or two every hour or so. Continue this for a day, then transition him back to his regular diet. If he refuses all food, or continues to vomit after eating &/or drinking, please have Louis evaluated. I hope he is feeling better soon. Take care.

My dog vomited chunky food and is lethargic. Did he eat chicken bones?

It sounds as Louie 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 him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.

What to feed a dog with an upset stomach after eating human food?

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 Luna's normal diet. If 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. Stop giving her food like carne burritos and bologna. They are not healthy for her and cause GI upset. She doesn't need bread either.

My dog won't eat, has upset stomach, and threw up. What now?

Since last night was Halloween, think about if there's anything she could have eaten that she shouldn't have and take her to the vet ASAP if you realize your chocolate stash or your entire pan of bacon wrapped something or anothers from the potluck is missing. If you can't think of anything she ate, it's generally ok to wait 24 hours to see if she get back on her food naturally. Sometimes something goes wrong in the gut and we don't know why but it resolves quickly. If she's not back to normal in 24 hours, or has any vomiting or diarrhea in the mean time, she needs to go to her vet for evaluation and supportive care. I hope she's feeling better soon and thanks for using Petco Pet Education Center, formerly Petcoach!
