Dog Vomiting Mucus? Here’s Why, and What You Can Do About It

Dogs can vomit a little after overeating, but if you notice your dog vomiting mucus then there might be cause for concern. Find out why this happens and what you can do to help.

If you notice your dog vomiting mucus, it may be cause for concern. But before you freak out, make sure you know all the facts first.

Vomiting in dogs is often confused with two other health conditions—the regurgitation of food (which is often covered in mucus), and expectoration, or coughing up mucus.

When you tell your vet that your dog has been vomiting mucus, she or he will likely want to rule out regurgitation and coughing as the culprits before determining what could cause your dog to vomit mucus.

Vomiting in Dogs

Vomiting does often begin with a form of clear liquid leaving the mouth—drooling. When plagued with nausea, dogs often drool and swallow more than normal. You’ll notice, that unlike in regurgitation, yacking is an active condition—your dog’s stomach will move in effort to bring up whatever’s going to come out of her or his mouth. Bile—usually a yellow or orange liquid—will often be present since this vomit has traveled from the stomach or intestines.

The cause: Some of the causes of vomiting in dogs include digestive issues, diabetes, and kidney failure. If your dog solely vomits foam or a yellow or clear liquid, it could indicate acute gastritis, pancreatitis, intestinal blockage, or other issues.

Regurgitating in Dogs

When regurgitating, your dog’s fluids and foods will escape easily—typically in a tube form (shaped like the esophagus it’s just traveled from), covered in a slick layer of mucus—without having to work at it. Your dog may even be as surprised as you are by this occurrence. There may be symptoms of coughing and gagging. Bile is not likely to be present. After regurgitation, your pet may want to eat the food that’s just resurfaced, so speedy cleanup is advised.

The cause: Usually regurgitation is the result of a glitch in the throat, esophagus, or the valve between the esophagus and the stomach.

Coughing in Dogs

If you’ve witnessed your dog hacking up mucus or foamy liquids, your pet may be coughing, not vomiting. The parts of the body that move visibly while a dog is coughing are the chest and ribs.

The cause: This symptom could signal a problem with your dog’s esophagus, respiratory system, sinuses, or heart. To learn more, read about gastritis in dogs and coughing in dogs.

Sounds more serious than an upset stomach. I would take the dog to the Vet asap if you haven't already.


been vomiting 2 days and hasn't eaten in 52hrs - doesn't want food


Everyone in this thread is an idiot. Do you really expect someone is going to answer your cry for help after describing this vague problem your dog has??? The answer to almost every single question is, take your dog to the vet. Wth


my dog is 13 golden and is throwing up foam and bile and also her hind legs are so wobbly she can not wald. I am sure something happened yesterday


Is it ok to have him drink water or liquids during this period


I had to put my dog down because he had a growth on his right cheek on his face. It was leaking blood everywhere. He was going to turn 10 on the 14th of March of this year. I cried when we put him down. He was put down in July of last year.


scrambled Egg, rice and cottage cheese seemed to be mild enough that it settled his stomach and the vomiting stopped.

And then mucus stuff... He felt better for the rest of the day barely coughing then today it's been none stop throwing up mucus.

He's a lab 6yrs old in October and he is a chunk weighing 106lbs


No. Do not give Pepto Bismol to dogs. My vet advised me against it.


When i got home i saw that my poodle had thrown up a seemingly thick yellow liquid. There didnt appear to have been any food in it. Any ideas?


My fur baby is a little over a year old very healthy energetic guy in the past few hours he's not been himself he's not bad lethargic but don't want to move much then he started vomiting white mucus dog food and grass...I have him pepto the vomiting subsided but are there any known k9 flus going around. No sneezing, coughing or diarrhea


Mine has to has yours improved


Take your dog to a vet immediately. It's an infection the in the digestive tract. I lost my Rhodesian Ridgeback to it, because all the vets misdiagnosed.


You guys haven't made that correction. You need to.
