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 (sometimes indicated by raising the back legs and pressing the front portion of the body to the floor)
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 will check for gastrointestinal cancer which causes many similar symptoms. 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 further check for cancer and 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 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.
Stomach and Intestinal Inflammation Questions and Advice from Veterinary Professionals

My 4 year old Chihuahua has had stomach issues since I adopted him when he was 2.5 years old. He will throw up rather frequently ( once a week or once every two weeks) as well as act as if he is in pain by not being able to get comfortable. He will often lay just the front of his body down or lay down then quickly get up and move to another spot. These episodes usually last for a few hours and with time he comes out of it but it happens frequently. He has been to the vet multiple times and we have tried to change his diet ( he eats homemade food now) He also gets a pr- biotic. His vet originally felt his diet was too high in fat. I am at a loss as to what is causing this as his tests have not indicated any issues. Anyone else experience similar symptoms in their dog? I'm at a loss! He also eats dust or grass when he doesn't feel well.

My 6y/o GSD neutered male has had quite the bad experience. He had 2 cblo surgeries a few years ago. This January he presented a small wound on his inner knee. It would close and then re open. Once it started oozing and holding fluid, I got my vet involved. We started him on Clindamycin 300mg twice a day and the wound healed. We still removed the hardware for the effected knee and cultured. Cultures came back as MRSP. We started him on 900mg of Clindamycin once a day. After a few weeks, he started acting very anxious and less interested in eating. We stopped the antibiotic and took him in for bloodwork which was all normal. He then stopped eating even when we tried human cooked food. Dropped him at the vet on Wednesday. He had lost over 12lbs. He wouldn’t eat for the vet either so they started him on an IV with nutrients and an appetite stimulant. Friday morning they came in to find Baron showing signs of vestibular disease. He was put on a high dose of steroids. His ears are clear. New bloodwork showed low albumin, mildly high globulin and slightly elevated white count. UA normal. Sonogram of abdominal normal. Endoscopy showed mild stomach irritation but, considering no food pretty normal from acid. Not enough to make him not eat. No skin wounds or rashes. Vet thinks PLE. Did biopsy of intestines. Said they looked a little redder than normal but everything else was good.
Any ideas out there? Help. This is killing me.

My 9 month old chihuahua has been very down lately. He’s usually a happy hyper pup but for the last few days hasn’t been eating or drinking and isn’t excreting properly. Instead it is just blood coming out of him. He just wants to lie down and sleep all the time. The vet said it could be inflammation? We have been given anti biotics and a syringe full of stuff to make his pop harder. How long will he be like this and is there nothing else more serious it could be? We can’t stop worrying this is so not like him. He also has a red gooey left eye is this caused by the problems in his stomach?

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?

Hi my Himalayan cat has crystals in his urine about 7 months ago and was rushed to the animal emergency. He was given very good care and has recovered well. He was put on Hill's prescription diet urinary care c/d food. He is now very well.I read I can buy urinary diet from Proplan and not buy the prescription since he is eating and doing well. He far prefers the Proplan as I got it one night when we ran out of the prescription food. What do you think?
Thank you in advance

my 13 year old Pekingese's stomach is bloated and his anus is very swollen and red. His poop is very tar-like and small bits. He still walks around but only to drink water and poop. Most of the time he is just laying around, but he does lift his head and still eats (not as much as before though). I am so worried! Please help

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?

I have a 3 year old pit bull mix. She loves to eat, is exercised 45-60 min every day and does not eat any table scraps or other food than her regular dog food which is Nutrish chicken and rice. Approximately every week to 2 weeks she wakes up with a very noisy stomach, does not eat her normal breakfast and usually throws up and has diarrhea for a portion of the day. The next day she is back to normal and is fine until the next episode about 2 weeks out. Any thoughts or suggestions on what to do?

My 9 yr old boy has inflammed intestines and his symptoms have persisted for over a week. He seemed to be doing better this weekend but he seems to be going backwards. He is not vomiting, he barely poops and when he does its very soft. He is eating and drinking in small portions, not as much as before. But his lack of energy and returning pain is worrying me. There is a clear increase in his energy when his medication kicks in. However, I would like to get him back to 100% as soon as possible. His current diet is boiled chicken and brown rice.

Hello,
My 7 month old Doberman pincher was showing signs of sickened for one day when we decided to take him in to see the vet. After blood work and X-ray they decided that a small object was blocking his intestines, they couldn’t remove the object only by performing surgery, my concern is that the vet said that while he was doing surgery my puppy’s intestines looked very angry, almost like he ingested acid, is that ever going to repair or heal itself with proper nutrition and medication? I want my dogs to enjoy quality of life and not be in pain. He was on a raw diet prior to surgery. All his blood work and vitals were in great shape before and after surgery, it’s only been 24 hrs. Thank you for your advice, it means a lot.

My 7month old Yorkie/ Maltese Mix Fenty weighs about 4lbs and has been sick for about two weeks now eating much and barely drinking water. I’ve taken her to the vet three times. The first time I took her in because she was throwing up yellow bile and excessively and she had diarrhea. They did x-rays and said they didn’t find anything alarming besides that her intestines looked swollen but they didn’t seem worried and gave her subQ fluids, cerenia injection and send her home with metronidazole and FortiFlora for 5days. On the 3rd day after our visit she threw up again though her pop looked normal and she no longer had diarrhea so I took her in to have blood work done. They injected fluids again and B-12 she slept for most of the afternoon but got up like 7hrs later wanting play, ate her kibble, drank a little bit of water and was acting like her normal self. The follow day the vet calls me and tells me everything they tested for was normal and to continue to give her the metronidazole and see what happens. The following day she started to loss her energy again, she wouldn’t eat or drink water, she wasn’t herself so the vet recommended an ultrasound. Yesterday they did the ultrasound and said they found irritation of the stomach and intestines again they gave her guilds and cerenia and prescribed another 5days of metronidazole. I read the discharge paperwork and the diagnosis says gastroenteritis small but normal adrenal glands. And they recommended I make her an appointment another doctor for further diagnostics such as ACTH and GI Panel. I’m scared that one I’m over medicating her and two all these vet visits are stressing her out. I’m not sure what I should do. I feel so helpless and I don’t want to keep putting my baby through tests I’m scared her little body cannot handle it. Please help.

I have a pitbull (2 years old). About a month ago he chewed a large portion of his Kong bone and swallowed it. For about a week we searched his poop to make sure it passed.. But never did. He never lost his appetite or had trouble going to the bathroom so we didn't think too much of it. Well about 4 days ago, he threw up and the Kong toy flew out of his mouth... IN HIS SYSTEM FOR A MONTH!! about 3 days ago, I noticed his anus was very red and he can't stop licking it... Today while picking up his poop, I noticed it looked like it was in a sausage casing..i did research and basically said it was inflammation of the intestines...it's this caused by complications of the toy in his system or just a need of change of diet? i haven't taken him to the vet because I don't have money for the visit and tests..

I adopted a chihuahua pup 2 years ago & she has experienced the same as your fur baby. We’ve spent oodles of $$ on testing, the last step was an endoscope w/ many biopsies, she has chronic inflammation of the small intestine. She is on a special diet with limited ingredients (7oz. Split into 4 meals), anti acid x2 (5mg) per day & a Rx of Metronidazole x2 per day, plus Cerenia for nausea on the really bad days. Her vomiting episodes are about every 1-2 months now vs. 1-2 weeks. She still seems to get belly aches often & is very gassy (toots & lots of burping). I feel horrible for her & am amazed by how much she can vomit on the bad days (sometimes diarrhea too), poor little rescue girl. Hope this helps in any way.
