Why Do Cats & Dogs Get Upset Stomachs?
A cat or dog upset stomach can occur primarily due to:
- Diet
- Food Allergies
- Intestinal Dysbiosis
- Chronic GI Disorders (e.g. IBD or IBS)
- Other Health Issues (e.g. kidney disease)
- Pica or Eating Spoiled Food
- Parasites or Infections
- Obstruction
It is essential to take your pet to the veterinarian for an examination and laboratory testing to determine the cause of your pets' upset stomach. Your vet may ask you to bring in a stool sample. A fecal analysis will provide valuable information about your cat or dog's microbiome, including the presence of parasites, bacteria and inflammatory cells. Laboratory testing for conditions of the liver, kidney and pancreas can also help your vet to determine what is causing the upset stomach.
Many pets may have a normal fecal analysis but still have an upset stomach. Most pet digestive disorders occur because of the pet’s diet. Just because a brand is considered premium or organic doesn’t mean it is right for your pet. Many of the best-selling premium brands contain grains and hidden fillers that can cause a variety of digestive problems and, subsequently, a weakened immune system. Pets can also be allergic to some of the ingredients, which can cause a great deal of inflammation. Please see our detailed discussion about pet prescription diets.
The key to good digestion is a healthy, balanced microbiome. A proper ratio of good-to-bad bacteria is essential to ensure your pet's digestion is working properly. If the good bacteria balance is upset, it can result in a multitude of digestive disorders. Using supplements to improve your pet's intestinal balance and overall digestion can help relieve your cat or dog's upset stomach.

Common Digestive Problems in Dogs & Cats
Listed below are common digestive problems that can cause your cat or dog to have an upset stomach. If you scroll down, you can click on our natural pet supplements and view testimonials from real pet owners whose pets have experienced relief from vomiting, diarrhea, acid reflux and other digestive disorders.
Inflammatory Bowel Disease or IBS
IBD (Inflammatory Bowel Disease) and IBS (Irritable Bowel Syndrome) are characterized by an abnormal accumulation of inflammatory cells in the lining of the intestine. This can result in gas, mucus and bloody stool. Pets with IBD and IBS frequently experience diarrhea, vomiting and gurgling tummies. These conditions are commonly caused by food intolerances or stress. Learn more about feline IBD/IBS and dog IBD/IBS.
Acid Reflux & Heartburn
Acid reflux and heartburn are quite common in pets. The symptoms can be subtle, like not always wanting to eat or rushing to eat grass and vomiting afterward. Acid reflux is uncomfortable, and cats and dogs will make gulping noises or have gurgling stomachs. Acid reflux and heartburn are typically a result of poor digestion or food allergies.
Colitis
Colitis is an inflammation or irritation of the colon or large intestine. It commonly causes gooey diarrhea featuring mucus, fresh blood or both. It is often accompanied by cramping, gas and an urgency to defecate. Adding our cat and dog colitis natural treatment is a great first step in helping your pet, but it is important to identify the possible culprits that are causing your pet’s colitis. Eating too many treats or raiding the trash can cause colitis, or it may be stress-induced. For example, a visit to the vet can cause stress colitis in dogs and cats. A pet can quickly become very weak and dehydrated from bloody stools. Our supplements for colitis in dogs and cats gently restore and rebalance your pet’s microbiome (the community of microorganisms in your pet’s intestinal tract) to help your pet feel better again.
Hairballs in Cats
Hairballs in cats are the result of grooming and swallowing hair. The hair can accumulate in the stomach, and your kitty will retch and hack until it vomits the hairball. Cats that have intestinal motility or digestive problems tend to have a more difficult time with hairballs. By improving digestive problems, most of the hair should pass through the digestive system. One of the biggest causes of digestive problems in cats is their diet. Dry food, for example, is high in carbohydrates. Cats are carnivores and not big water drinkers, so they should eat a high-protein, high-moisture diet. Cats frequently have food intolerances and allergies to ingredients such as dairy and fish, so feeding a low-carbohydrate hypoallergenic diet can help with overall digestion and managing vomiting from hairballs.
Adding Power Probiotic can also help to improve your cat's digestion. Adding a small amount of canned pumpkin or mashed sweet potatoes to your cat's food can add fiber, which is important to help keep the hair moving through the intestinal tract. Brushing your kitty a few times a week will help to remove loose hair and improve the skin and coat.
Perianal Fistula in Dogs
Perianal fistula in dogs is a painful opening in the skin surrounding the anus. When the condition is mild, you may not notice there is a problem, but as it continues to progress, watch for signs of your pet straining to defecate, blood in the stool and a decrease in appetite. You might also notice that your dog excessively licks its tail and hindquarters, often leading to infection and chronic draining ulcers that are very painful.
Older German Shepherds are the most commonly affected, but perianal fistulas can occur in any breed of dog. While the external sores and lesions are red and painful, most of the other signs appear to be digestion related. Adding Power Probiotic can help to replenish good bacteria in the digestive tract and Amazing Omegas for Pets can help to reduce inflammation and make bowel movements easier.
Digestive Parasites
Parasite infestations can cause inflammation in the intestinal lining and subsequent weakening of the immune system. The parasites will literally eat your pet's food and nutrients. Parasites can be transmitted by water or fecal ingestion. They are highly contagious and will require antiparasitic medications from your veterinarian. The medications will kill the parasites, but there may be long-term impacts on your pet's immune system, digestive system and bowel function.
Gastric Ulcers
Gastric ulcers in dogs and cats occur when the mucosal lining of the stomach or intestine has been damaged and the strong digestive acids cause painful lesions to form. The most common causes of ulcers are the use of nonsteroidal anti-inflammatory drugs (NSAIDs such as Rimadyl, Deramaxx or Meloxicam) or an overgrowth of Helicobacter pylori (H. pylori) in the gut. Ulcers can also be caused by accidental poisoning (toxic plants, pesticides, chemicals), infection (bacterial or viral), parasites, IBD, kidney or liver disease and trauma. Older dogs can develop acid stomach from taking NSAIDs to treat their arthritis or hip dysplasia.
Symptoms of ulcers in pets can include vomiting, abdominal pain (may avoid certain positions and be sensitive to touch), black tarry stool due to digested blood, and loss of appetite. The goal of treatment is to relieve discomfort and promote the healing of the ulcers. The first step is to eliminate the cause of the ulcer, otherwise ulcers will continue to form.
Using supportive natural supplements can help relieve your pet's discomfort. Gastro ULC, Power Probiotic and Soothing Digestive Relief work together to promote a healthy digestive tract and reduce irritation from stomach acid. If your pet's ulcers are from NSAID use, natural joint support supplements such as Ultra-Flex Collagen or ArthroSoothe can help reduce or eliminate the need for NSAIDs and pain medications.
Recommended Diet for Dogs and Cats With Digestive Disorders
Many times, pets with digestive disorders are eating foods with ingredients that cause intestinal inflammation or that the pet has an intolerance to. Digestive issues are often treated by using "prescription" diets and medications. These prescription diets typically contain byproducts, fillers and chemicals. While the diet may help in the short term by reducing fat and adding fiber, giving your pet these ingredients can introduce other problems such as skin irritation, itching and dull coat. Over the long term, the ingredients can exacerbate allergies and cause inflammation. Please see our article about pet prescription diets.
In general, pets with digestive disorders should eat a grain-free, hypoallergenic diet. Most pet owners find that just by making changes to the diet, along with adding a powerful probiotic and digestive enzymes, their cat or dog's digestion quickly improves. Ask Ariel's Pet Nutritionist offered holistic consultations in conjunction with veterinarians at VCA hospitals for over 10 years. Her diet and supplement protocol for dogs and cats with digestive disorders has been recommended by veterinarians nationwide.
