Senior dogs vomiting a yellow-colored fluid might have bilious vomiting syndrome. In elderly dogs, it is caused when your dog vomits a few times a week. This is often seen early in the morning when your dog first wakes up and has an empty stomach. 

Many dogs who have mild cases of bilious vomiting can easily be cured with at-home treatment such as a bland diet, small frequent meals, and medications to help decrease stomach acid. In this article, we will review the 5 best home remedies, and when to call your vet for help!

5 steps you can take at home to help your dog [home remedies]

Many dogs can easily be treated with lifestyle modifications. Feeding a bland diet and avoiding high-fat diets and human foods can often help treat bilious vomiting syndrome in your older dog. These are some at-home remedies that you can try to help treat this condition before seeing your vet:

1. Offer a bland diet.

Bland diet such as chicken and rice can help keep your dog’s stomach calm.

If you don’t have chicken or rice, you can read our article about the best bland diets for dogs to discover other options. You can also purchase a sensitive stomach diet at the pet store to feed your dog. Many dogs can have recurring issues that require a specialized diet for their entire life. Cooking at home may not provide all the necessary nutrients for a balanced diet.

2. Feed small frequent meals.

Many times, dogs with bilious vomiting syndrome will vomit more often when their stomach is empty. By feeding a small meal frequently will help keep their stomachs full of food. Usually feeding your dogs every 3 to 4 hours will help treat bilious vomiting syndrome. 

3. Feed your dog right before they go to bed.

This is often the only change that dogs need. This helps ensure that they do not have a prolonged period of time without any food in their stomach. 

4. Give a gastric acid reducer.

Over-the-counter medications intended to decrease gastric acid production will help treat bilious vomiting syndrome. Commonly used medications are Pepcid, or Prilosec. However, it is important to talk to your vet before giving your dog any medications (even over the counter medications). Some medications may not be good for your dog depending on their health profiles.

A study published in 2016 shows that most dogs quickly improve with lifestyle modifications and gastric acid reducers. Many times older dogs have very good success with these treatments as long as there are no underlying issues or other diseases that they also are dealing with.

5. Avoid human food and dog treats.

Some dogs have very sensitive stomachs, and any human food or high-fat dog treats can cause them to have GI issues. 

Our patients sometimes ask us: are there herbal remedies for dogs vomiting yellow bile? You can give your dog herbs such as catnip, fennel, chamomile, peppermint, and ginger to help decrease vomiting and nausea in dogs. 

Finally – see your vet. For dogs who continue to vomit, it would be best for them to see your veterinarian. Your vet will be able to prescribe medication to help decrease their vomiting and calm their stomach. There are also prescription diets that your vet can recommend for you to treat bilious vomiting syndrome. 

You should not try home remedies if your dog is lethargic, vomits blood or shows other signs of illness

Sometimes at home treatment for bilious vomiting syndrome should not be tried. If your dog is very lethargic, vomiting blood, dehydrated, or also having diarrhea, it is best to not try any at-home treatments as your dog needs more intense and immediate veterinary care. Delaying veterinary care could have a very negative impact on your dog’s health.

“It is important to take your dog to see a vet, even if home remedies provide temporary relief, as a vet can accurately diagnose the underlying condition causing the vomiting and provide appropriate treatment.”

When to try home remedies / when to see the vet

If your dog vomits yellow bile just once and is otherwise acting okay there is nothing to be worried about. Some dogs will eat something that they should not have such as a bug, or human food. This can cause them to vomit yellow bile. However, Dr. Ochoa explains more severe cases that need a vet’s intervention:

“Some dogs will also continue to vomit and become lethargic. If this happens, your dog should see a vet right away. While bilious vomiting syndrome in older dogs is not a life-threatening condition, the condition can cause other issues to develop such as pancreatitis and GI ulceration leading to continued vomiting, diarrhea, and blood in the stool or vomit. These can become life-threatening if left untreated.”
