Dog Throwing Up White/Yellow/Foam?

What to Look For

There are different meanings for different types of vomit. Some are more serious cases that need to be dealt with by a veterinarian as soon as possible, where as some may be treated at home. Some dogs deal with constant upset stomachs, and a few changes in his daily routine may help solve the problem. Sometimes, it is a once in awhile occurrence, but still needs to be examined to determine severity.

Vomiting is a very unpleasant thing to deal with, but it is important to pay attention to what your dog may be vomiting before you clean it up. This can be very helpful when dealing with an illness, and you can sometimes determine if your dog ate something he shouldn’t have.

Dog Vomiting Yellow

There are two main reasons for yellow vomit. The first reason is because of excess bile in the stomach. This could happen right before a meal, or because his stomach is empty. This is usually treated by changing your dog’s food type and feeding schedule.

Another reason for yellow vomit is because your dog is eating too much grass. This is most obvious if you have recently let your dog out and he comes back in the house and vomits shortly after. Keep an eye on your dog when you let him outside to relieve himself. If you notice him eating an excess amount of grass, correct the behavior right away until he stops.

Dog Throwing Up White Foam

Vomiting white foam is a serious issue. Sometimes it is caused by a consumption of garbage, spoiled foods or another foreign substance. If your dog’s behavior goes back to normal after a bout of vomit, he will likely be fine. However, if the white foamy vomit occurs more than once, it is important to determine the exact cause.

Kennel Cough – White foamy vomit with mucous may be because of a respiratory disease called kennel cough. Look for other symptoms such as sneezing, hacking sounds, trouble breathing and eye and nasal discharge.

Bloat – Bloat is caused by a swelling of the stomach. The swelling will cause the stomach to rotate. This is a very serious condition and will cause death if left untreated. It may be caused by overexercise, or eating too fast.

Symptoms of bloat include white, foamy vomit, hunched back, bloated stomach region, panting and restlessness. Sometimes vomiting will not occur again after the first time but there will be attempts to do so. Take your dog to the veterinarian immediately.

Digestive Tract – If your dog has complications in his digestive system, he may throw up white foam. If this happens on a regular basis before meal time, it may be an infection of your dog’s digestive tract. As long as there is no blood in your dog’s vomit, treatment may be as simple as a change of food.

Illness – There are many different illnesses that can cause white, foamy vomit. Minor illnesses include the flu. Some more serious cases include diabetes, kidney disease and hepatitis. Be sure to look out for irregular behavior and other symptoms such as diarrhea, lethargy, pain, panting, refusing to eat and discharge.

Rabies – Although foaming at the mouth will not likely occur until other symptoms are in full swing, vomiting white foam may be a sign of rabies. Other symptoms of rabies include aggressive behavior, fever, licking and chewing the bite mark and loss of appetite.

The foaming occurs when the nerves in the mouth and throat become damaged from the disease. This makes it impossible for your dog to swallow his saliva, therefore creating a “foaming at the mouth” characteristic.

Dog Vomiting and Blood

This is the most serious of the vomit types. Vomiting with blood is usually means there is an infection or obstruction in the stomach and intestines. Some causes of bloody vomit may be :

  • Rat poison. Rat poisons cause the blood to thin and may excrete in vomit, diarrhea or body cavities.
  • Swallowing sharp objects which tear the stomach and intestines.
  • Eating dead animals, this may cause your dog to catch disease from the animal and cause blood in the vomit.
  • Ringworms from unvaccinated puppies.

Usually bloody vomit is accompanied by bloody diarrhea. More serious cases of bloody vomit and diarrhea include cancers and internal hemorrhaging. Take your dog to the veterinarian immediately if the blood is bright colored in the vomit or diarrhea.

Dog Vomiting Yellow bile

Dog’s are prone to accumulation of stomach bile and acids. This excess will cause irritation and upset stomach and will cause your dog to vomit. This is because your dog’s stomach is not full enough from his meals, or he digests his food too quickly to sustain any food in the stomach.

Your dog’s food may be the cause of excess bile. Dry dog food is not recommended for dogs who throw up bile because it soaks up liquids in your dog’s stomach, which will expand and may cause vomiting.

In very serious cases, excess bile may be diagnosed as IBD, or Inflammatory Bowel Disease. This requires medical attention and a special diet to control.
