Why does my dog's vomit smell like poop after eating new wet food?

As a veterinarian, I become very worried when I hear about vomit that smells like feces. It could be something as silly as Koa ate some poop, and now she's vomiting it up because eating poop is gross. However, it could also something much more serious. Vomit can smell fetid when there is an intestinal blockage, like she ate a sock or corn cob, etc, or if her intestines are bunch up and this is causing and obstruction (this is called an "intussusception" and can happen in puppies.) If she vomits once, and is otherwise doing well-- eating, drinking, playing, etc, then it may be the former scenario. However, if she looks like she feels crummy, she continues to vomit, she's not eating, etc etc etc, I would take her to a vet as soon as you can. Intestinal obstructions are very serious and require emergency surgery. Best of luck to you!

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 the vomiting stops, continue feeding until the stool is normal. Transition slowly to the regular diet. If the vomiting or diarrhea don’t stop, see your veterinarian. The fishy odor is likely from her anal glands. These glands are located around her rectum and are responsible for scenting and marking. They get expressed (or emptied) during defecation but sometimes, they can get too full and inflamed or infected. Occasionally, an abscess can form requiring lancing, flushing and antibiotic therapy.

It is unlikely that the wet food is causing the diarrhea. Especially if the wet food has been fed for many years. With Samwise being so old I would recommend taking him to a vet to see what is going on. Chronic inflammation and even neoplasia can cause horrible diarrhea. A vet visit with some blood work and x-rays should be done. hope she feels better

It sounds as Rissoto 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.

The odd look is probably due to the mixture of wet and dry food, and I suspect the wet food is causing Simba's vomiting. The addition of a new food suddenly can cause stomach upset. Feed him 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 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.

It could be either dry vomit or dry feces (if the it smells like food, it is more likely to be vomit though). Just to be on the safe side, start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if you notice diarrhoea, more vomiting, lethargy or inappetence.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Eris. Poor girl. It could be something she ate, but it could also be a GI illness. Feed her 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 she vomits the bland diet, refuses to eat the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away. I hope this helps!
