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.

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.


2016-06-04T17:11:54

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

My dog just-started throwing up very concerned what should I do?


2015-05-06T19:50:54

I had a barrel chested dog. Took him out walking three times one day and he was happy, strong, and healthy. Later that night he began to vomit white froth, was complaining, lethargic, etc. I took him to the vet the next day and they went in for surgery of a "flipped" stomach. When they got in the stomach had been severley damaged and had turned black. I had to have him put down. So beware folks. Doesn't take long. I love that dog.
