Signs Of Nausea In Dogs

If you find a mysterious pile of vomit in your home and are unsure which dog is responsible, there are a few ways to point out a nauseous pup.

A dog that just vomited may be drooling, appear lethargic, be uninterested in food, and may not be interested in things that usually make them happy. These are some of the main signs of nausea in a dog, and can help you determine which pup needs attention.

Dog Vomiting vs. Regurgitation

While dog regurgitation looks an awful lot like vomiting, it’s actually a different function altogether; with regurgitation, food or water your dog has just consumed is expelled from your dog’s esophagus immediately after eating. Regurgitation is typically caused by your dog eating too quickly, or being active right after eating, and isn’t usually a cause for concern.

Understanding the vomit color can help you be aware if your dog is OK or if there might be an emergency happening. Usually dark vomit is a bigger sign of a potential issue like stomach ulcers, so pay particular attention to those.

White Vomit

White or pale vomit may contain food that has been digested, especially if your dog hasn’t eaten for several hours. But if you have a dog throwing up white foam, this may indicate the dog’s stomach is empty, and they’re vomiting saliva and liquid only.

If your dog is trying to vomit but cannot, or they’re repeatedly bringing up small amounts of white foam, this could indicate bloat or more severe gut problems. This could be an emergency, and you should call the nearest open veterinary clinic immediately.

Yellow Vomit

If your dog’s vomit color is yellow. In that case, what you’re seeing is known as bile.

Bile is a fluid the liver produces for digestion. It goes from the liver to the gallbladder, where it is released into the small intestine, it can irritate the digestive system, and eventually vomit.

Yellow dog vomit is usually harmless. As long as your dog is healthy, you don’t need to be concerned.

Green Vomit

Bright green vomit can be an indicator they were snacking on some grass or it can be bile which a dog might vomit if they have an empty stomach. Keep on eye on them for a bit, if they vomit once or twice and then stop they are probably OK. Some dogs will purposely eat grass if they are not feeling great to help the dog’s stomach feel better.

If green dog vomit becomes more frequent, then a visit to the vet is recommended.

Red Vomit

In 99% of cases where vomit is red, it’s because blood has something to do with it.

If the vomit is a striking red, it likely contains fresh blood. This could be the result of trouble with your dog’s stomach lining, possible inflammation or a response to having ingested a poisonous substance.

Dark red vomit means that the dog is vomiting up blood that has been in their system for a while – in other words, digested blood. If your dog vomits blood repeatedly, you should contact your vet as soon as you can.

Brown Vomit

Brown dog vomit can indicate a few things. The cause behind it may just be due to the color of your dog’s kibble.

A more alarming reason behind your dog’s brown vomit is due to eating feces. Eating stool, coprophagia, is quite common in our canine companions.

You can often tell if your dog is eating stool by not only the color of their vomit, but also the nasty yet familiar smell.

Black Vomit

Black vomit can be due to your dog ingesting something of a similar color (such as farm animal poo or mud/dirt). However, black vomit can also indicate digested blood caused by eating toxins or bleeding within the gut. Black vomit shouldn’t be considered normal, and urgent veterinary advice should be sought.

When Should I Worry About My Dog Vomiting

If the vomiting is a one-off, it’s usually nothing to worry about as a general rule. If it happens repeatedly, or if you’re concerned, always contact your veterinarian as soon as possible. Signs your dog may need urgent veterinary care for vomiting include:

● Loss of appetite
● Lethargy
● Weakness
● Abdominal pain or swelling
● Potential toxins have been ingested
● Foreign material in the vomit (e.g., toys, plastic, or clothing)
● Red vomit or vomit that contains blood
● Black vomit
● Dark brown vomit
