The Different Colors of Dog Vomit and Their Meaning

Remember, dogs are complicated animals, and sometimes, their vomit can mean more than one thing. So, while it’s always best to bring your dog to a vet to get a proper diagnosis, here’s a quick guide that can give you a general idea of your dog’s health when they vomit.


Is your dog vomiting white foam in the morning before eating? Or did you find a white pool of vomit in the kitchen while doing the dishes? Usually, white vomit is basically foam on top of your dog’s vomit. This happens when the puke comes into contact with air and can also be caused by the vomit sloshing around in your dog’s stomach.

Dog vomit tends to be extra foamy when they have an empty stomach. So, if you notice white foam in your dog’s vomit before they eat, it probably means that they have an empty stomach. However, keep in mind that it isn’t the foam you should be paying attention to, as foam appears in the vomit of many dogs.


Brown vomit in dogs means a lot of things. Most of the time, it’s because of the color of your pet’s kibble, which is usually brown and red. If you see kibble in the brown vomit, it’s usually nothing to worry about.

However, brown vomit can also be caused by your dog eating feces. Now, this sounds gross, but it’s very common for dogs to ingest feces from time to time, which can cause some health problems.


The most common reason for green dog vomit is that they ate grass in the yard. If you see plant material in your dog’s green vomit, it simply means they snacked on plants while they were outside.

However, green color can also indicate bile in the vomit, which can happen to dogs with an empty stomach or those suffering from acid reflux. If your dog vomits without food in its stomach, this could indicate a more serious problem, and they should be brought to the vet immediately.


Red vomit can be very alarming. Since it’s the same color as blood, this type of puke tends to freak out some dog owners and cause them to panic. However, before you start panicking, check the color of your dog’s kibble, and if there’s some red in it, that could be the cause of the color, especially if there’s kibble in the vomit itself.

However, if your dog doesn’t eat red kibbles, then that might indicate blood in the vomit. Bloody vomit can be caused by stomach ulcers and other gastrointestinal conditions and requires a vet’s attention immediately.


If you see yellow color in your dog’s vomit, that can mean there’s bile present. As we mentioned earlier, bile is usually present in a dog’s vomit if they have an empty stomach. It can also indicate acid reflux which is why it’s important to take them to the vet as soon as possible.


Clear vomit can also be an indicator of acid reflux, as this usually occurs if they vomit on an empty stomach.
