There are multiple different forms of vomiting in dogs. White foam or yellow foam are typically associated with upset stomachs, while bloody foam is cause for concern. The main reasons why vomiting occurs in dogs are upset stomach, parasites, and health issues like liver disease. Rabies is also suspected when a dog is vomiting foam.
Upset Stomach
More often than not, if your dog is vomiting white foam, the cause is most likely an upset stomach. When yellow foam appears, it is from the same cause; however, your dog most likely has an empty stomach. The yellow is merely caused by bile within the stomach. There are multiple reasons why upset stomach can occur:
- Drinking too much water after exercising
- Eating grass
- Swallowing something that can’t be digested
- Bloat
The condition known as bloat is the main cause for concern and should be checked out immediately by your vet. Failure to do so can result in death.
Rabies
One of the most common signs of rabies is an animal who has excess salivation and is vomiting foam. Other symptoms, such as fever, staggering, and paralysis may indicate that your canine has rabies. Unfortunately, once symptoms become apparent, the condition is in the final stages and often, the majority of dogs who have rabies succumb to the disease.
Parasites
Typically, parasites are more of an issue for younger dogs and puppies. Lots of worms within the system can be a heavy burden for the bowel lining, which can lead to blockage. This will then result in nausea and vomiting. While this issue is serious, it can be easily resolved with the proper medication. Take your dog to the vet if the vomiting is accompanied by:
- Lack of energy
- Poor appetite
- Pot belly
Health Issues
Older dogs tend to not be affected by parasites as younger dogs are, however their bodies tend to become the problem as they age. For instance, if your dog has liver disease, toxins will begin to multiply within the blood stream. This will cause the dog to become nauseous and vomit. A few other common health issues that can cause vomiting are uncontrolled diabetes, a womb infection (in a female dog) and inflammation of the bowels.
