What is Stomach and Intestinal Inflammation?
Inflammation is often the body’s response to an infection. Over the short term, it can rid cells of bacteria and disease, but kept up indefinitely, chronic inflammation creates its own problem. Inflammatory responses can be triggered in a dog’s stomach and intestine, sometimes in response to an actual infection, sometimes in response to a food or allergen, and occasionally due to a hereditary weakness. Once triggered, these responses can self-perpetuate to some degree since inflamed mucosa become even more sensitive to allergens. The result may be prolonged symptoms of digestive upset without an obvious cause. The problem can sometimes be alleviated by a change in diet. Severe cases may need medication to reduce the animal’s autoimmune response.
Inflammation of the stomach and intestine can cause acute and chronic symptoms of digestive upset. Long term conditions will put stress on a dog’s system and undermine overall health. A number of veterinarian defined diseases create this condition, including gastritis and inflammatory bowel disease.

Symptoms of Stomach and Intestinal Inflammation in Dogs
Frequent vomiting is a symptom which may contain the following:
- Undigested food
- Fresh blood
- Digested blood that looks like coffee grounds
- Froth
- Bile
Other signs which may present are:
- Diarrhea often with blood
- Dark tar-like feces that contains blood (melena)
- Straining to pass mucus covered feces
- Weight loss
- Lack of appetite
- Abdominal pain
Types
Inflammation can occur at almost any point along the gastrointestinal tract. Most forms of inflammation can be either short term or chronic.
- Acute gastritis - short term inflammation of the stomach that results in vomiting of blood, bile or undigested food
- Chronic gastritis - results when the vomiting has persisted regularly for more than a week and cannot be attributed to an isolated cause like food poisoning
- Eosinophilic gastroenteritis and Lymphocytic- plasmacytic gastroenteritis - severe forms of chronic gastritis which occur when eosinophil, or lymphocyte and plasma cells infiltrate the gastric mucosa
- Chronic atrophic gastritis - a form of chronic gastritis characterized by thinning of the mucosa, gastric gland atrophy and infiltration of mononuclear cells
- Chronic hypertrophic gastropathy - a rare form of chronic gastritis in which inflammation constricts the muscles and reduces gastric outflow
- Inflammation of the large intestine or colon - inflammation of the colon can be short term or long term, like gastritis. It is more likely to present bowel symptoms such as diarrhea and blood or mucus in the feces, than vomiting
- Eosinophilic enterocolitis and Lymphocytic-plasmacytic enterocolitis - similar versions of these gastric diseases in the colon.
- Granulomatous enteritis - a rare condition in which long term inflammation narrows the bowel opening
- Inflammatory Bowel Disease (IBD) - a diverse group of long-term inflammatory diseases including chronic forms of gastritis and colon inflammation where the mucosa on the walls of the gastrointestinal tract are infiltrated by immune-system, antibody cells
Causes of Stomach and Intestinal Inflammation in Dogs
Short term inflammation can often be attributed to poisoning, bad food or even overeating. Some possible causes of long term inflammation include:
- Allergens to chemicals in processed food
- Allergic reaction to a medication
- Unknown bacterial or parasite infection
- Hyper-immune response originally triggered by an allergen or infection that has become self-perpetuating
- Defective lymphoid tissue
- Genetic predisposition- some breeds are considered more likely to develop long-term inflammation including Norwegian Lundehunds, German Shepherds, Yorkshire and Wheaten Terriers, Basenjis, Boxers, English Bulldogs, Irish Settlers, Rottweilers, Chinese Shar-Peis, and Cocker Spaniels
- Psychosomatic factors
- Idiopathic (unknown)
Diagnosis of Stomach and Intestinal Inflammation in Dogs
Diagnosis of inflammation is often a system of elimination. There are many known viral and bacterial infections which cause vomiting, including canine parvovirus, so the veterinarian will first try to eliminate these as a possibility. Radiographs and ultrasound might be necessary to help with the diagnosis. Complete blood work will usually be taken. This often shows deficiency from constant vomiting and poor nutrition absorption, but if no other abnormalities are present it can rule out other conditions. Urine and feces tests can help to eliminate some known diseases.
The veterinarian may recommend an endoscopy or a colonoscopy to evaluate the state of the mucosa on the gastrointestinal walls. Biopsies are usually taken during these procedures to evaluate the cells at a microscopic level. Both of these procedures are somewhat invasive and will require an anesthetic. Your dog will also have to fast for several hours. Exploratory surgery is another option to ascertain the extent of the inflammation on the walls of the stomach or intestine.
All the information you can give the veterinarian regarding the type and frequency of the symptoms as well as when they first started will be important in making an accurate diagnosis.
Treatment of Stomach and Intestinal Inflammation in Dogs
Most dogs will be given medication to aid with the vomiting symptoms. Antacids and anti-inflammatory drugs are also commonly prescribed. Fiber is often added to the diet for dogs with colon inflammation. This can be effective for short term problems, but long term issues will often return.
Changing your dog’s diet is usually the first treatment for chronic inflammation. You may need to withhold food for several days, and start your dog back eating on the “novel protein diet.” This involves feeding your dog a type of protein he has never eaten before such as duck, or even kangaroo in order not to immediately retrigger the same allergic response. The veterinarian may also give you hydrolyzed protein, which has been specifically designed to minimalize the chance of an allergic reaction. Starting with the novel protein, you will slowly add elements back into your dog’s diet. If the symptoms start again, you will know what specific food triggered it, and you may be able to find a substitute.
If diets are unsuccessful, several medications can help reduce long term inflammation of the stomach and intestine. An immune suppressant, cyclosporine, is one common choice for limiting the auto-immune response and reducing inflammation. The steroid prednisone is also effective, and some veterinarians are turning to a dog adapted from of CellCept, the drug which is given to humans to avoid rejection of a new organ after a transplant.

Recovery of Stomach and Intestinal Inflammation in Dogs
Inflammation of the stomach and intestine isn’t usually dangerous or life threatening, but it can cause your dog a lot of misery. Follow the veterinarian’s advice and stick strictly to any dietary program. This may be difficult at times, especially when it requires withholding foods your dog loves, but it can be important for his recovery. In some cases your dog may be able to return to a more normal diet once the triggering factor is found; in others, you may have to manage his diet for some time. If the veterinarian prescribes a long term medication, check the side effects and try to give the smallest effective dosage.

Without examining Sasha and reviewing all records I cannot say for certain but if there is widespread inflammation, adhesions and there is an absence of peristalsis it may be a case that euthanasia is the most appropriate course of action. Regards Dr Callum Turner DVM

My pet has the following symptoms:
Anal Discharge
My 10 mth old Shih tzu has had diarrhea since yesterday morning. It was soft solid in the beginning with streaks of blood. Now it's bright red blood. No vomiting, still playing. Hasn't displayed any other issues. I've been giving her plenty of water but no food since yesterday. What can I do?

Large quantities of blood in the stool should be seen by your Veterinarian; a break in food is a good idea but you should reintroduce food after around eight or twelve hours offering boiled chicken and rice. But, ideally due to the large quantity of blood you should visit your Veterinarian for an examination. Regards Dr Callum Turner DVM

My pet has the following symptoms:
Diarrhea
Loss Of Appetite
Hi. I have a 9 month old American Bully male. In the past 2 months, he has had some problems with his stomach. Every other day he would refuse to eat anything, have a runny tummy, ranging between a light coloured mucus, to black tarry, to bloody, all in the same day. When he stops eating, he refuses to eat for a couple of days. I take him to the vet regularly and every time they say it's just gastritis. With the last vet visit about 6 days ago, I insisted on an xray being done, because I thought it might be something stuck in his intestines as he eats everything. No obstructions or foreign matter could be seen on the xray, but it was seen that ALL of his small intestines are very inflamed, but the big intestine seemed normal. He does not vomit at all. During the past 6 days, he has had antibiotics, liquid suspension and Royal canin Gastro intestinal diet. He is a big male, weighing 33kg, but has up to now, not even eaten 2kg of food over the past 6 days and now, while on medication, stopped eating again. I'm thinking of maybe trying to put him on a raw diet as my female pitbull of 6 years old was diagnosed with cancer in January and has since been on a raw diet and works wonders with her. Would a raw diet help him and improve his appetite and eating habits?

Generally I don’t recommend raw diets unless there are no other alternative options, if you are looking into raw diets I would suggest getting a raw diet from a dog food company rather than making your own as several nutrients can be missing from raw diets. A gastrointestinal sensitive diet (like the Royal Canin one) or boiled chicken and rice may help but it would be better to try and understand why the intestine is inflamed.

My pet has the following symptoms:
Black Tar Diarrhea
I Have taken our pup to the vet. Diagnosed with gastrointestinal disease. Urinalysis showed no signs of any parasites or parvo. Used up the antibiotics given and she has gotten worse. What once was just mild runny brown diarrhea has turned in to black tarry diarrhea and she's not wanting to eat or drink and her tummy appears swollen. We started her on probiotic today. What else can we do to help her condition and relieve her obvious pain and discomfort?

It is important to determine the specific cause of the gastrointestinal disease; the presence of black tarry diarrhoea is indicating digested blood which would be from a bleed somewhere in the upper gastrointestinal tract. If you haven’t done so already, you should have an x-ray done to determine whether there are any foreign objects, tumours or other indicators of a bleed. Regards Dr Callum Turner DVM
