Why Do Dogs Throw Up Clear Liquid?

Usually, if your dog drinks lots of water or drinks too quickly, they will probably vomit. 

However, clear liquid doesn’t always have to mean it’s water or saliva. The dog may have ingested something clear, which can’t be digested. 

Frequent clear liquid vomiting can be a sign of a digestive issue, stress, or more serious medical problems. Possible causes include:

Water Intoxication

Being over hydrated can be as dangerous as being dehydrated. Overhydration can occur when your dog drinks too much water, or consumes too much water while swimming.

Signs of water intoxication include bloating, lethargy, disorientation, and nausea.

If you suspect that your dog has water intoxication, especially if they have been throwing up water after swimming, you should take him to the vet immediately

Hypothyroidism

If your dog is suffering from hypothyroidism, which happens when the thyroid isn’t active enough, they will vomit a clear liquid, after drinking water.

Other signs of hypothyroidism include reduced heart rate, lethargy, excessive shedding of hair.

In some cases, the dog may have sudden limping, weird bending of the head, and disorientation.

Kidney and Liver Disease

Dogs may have kidney disease for months or years without showing signs, and that may develop to a kidney failure.

Kidney disease happens when the dog’s kidney is unable to filter waste from the blood properly.

Signs of kidney disease include throwing up clear liquid, excessive consumption of water, frequent urination, diarrhea, appetite loss, and bad smelling breath.   

The dog’s liver is also responsible for filtering toxins out of the blood. If the liver wasn’t working as it should, the toxins will build up and cause vomiting of clear liquid.

Other signs include diarrhea, lethargy, and loss of appetite. In severe cases, a yellow tint can be seen in the dog’s eyes. 

Pancreatitis

Pancreatitis is a very serious and painful disease, which affects the pancreas. The pancreas is located between the stomach and small intestine.

It produces enzymes to digest food and control sugar levels in the body.

If your dog is suffering from pancreatitis, they will vomit a watery liquid, have nausea, loss of appetite, and diarrhea.

Dogs with pancreatitis should be treated early, to avoid developing canine diabetes. 

Parasites

Another reason for vomiting clear liquid is ingestion of a parasite. Either by drinking polluted water, or by coming in contact with another dog infected with the parasite. 

One of the most common parasites is “Giardia”, this will cause your dog to vomit water, and cause diarrhea.

Dogs suffering from giardiasis will usually produce a green colored stool, covered with mucus. 

If you suspect that your dog is infected with a parasite, you should take them to the vet immediately.

Stomach Ulcers

Stomach ulcers can be a cause of vomiting water. A stomach ulcer happens when the stomach lining is damaged. This lining protects the stomach from the acid that digests food. 

Cause of stomach ulcers can be a parasite, toxin ingestions, tumors, and liver or kidney disease. 

Other signs of stomach ulcer in dogs include weight loss, abdominal pain, and anemia.

Tumors

Tumors can lead to vomiting water and food. If the tumor is near the vomiting center, it will result in more frequent vomiting.

Other signs include weight loss, loss of appetite, and blood in vomit. If you suspect your dog has a tumor, you should immediately take them to the vet.

What to Do If Your Dog is Throwing Up Clear Liquid

If your dog is vomiting clear liquid frequently, more than two times a day, and for several days, you should contact your veterinarian. 

However if your dog vomits clear liquid for the first time, keep observing your dog to check if it happens again. If the dog vomits again, skip the next meal. 

Feed your dog the next meal scheduled, after skipping one, and keep watching for vomiting and other signs of illness. Look for signs like weakness, diarrhea, or loss of appetite. 

Don’t give your dog water after vomiting, as it can upset the stomach more, and result in more vomiting. 

You can do that by removing the water bowl for a few hours, until the stomach is at rest, then you can try and give him small amounts of water.

In addition, don’t give your dog any human medications for vomiting, since they could make things worse. 

The best thing you can do is contacting your veterinarian, to better understand the cause behind vomiting clear liquid, to give the suitable care and treatment.
