Dog Colitis

Dog colitis refers to the inflammation of the colon. Mucus or bloody diarrhea, straining during and after defecation, and an urgency to go to the bathroom are the three big clues that indicate colitis in dogs. This page looks at the symptoms and possible causes of canine colitis. It also discusses how to use natural remedies such as herbs, homeopathy, and supplements to alleviate the symptoms caused by colitis.

Colitis is a rather common ailment and affects dogs of all breeds and ages. Colitis refers to the inflammation of the colon and is characterized by diarrhea or soft stools, sometimes with mucus, fresh blood or both in the stools. The stool may start out normal then finish soft or may seem gooey throughout.

A dog suffering from colitis may also have gas and stomach cramps. A dog with colitis usually exhibits a sudden sense of urgency - a sudden urgent need to go to the bathroom and, as such, may have "accidents" in the house.

Colitis in dogs can be acute - the symptoms come on suddenly and last for a short time, or chronic - the symptoms last for at least two to three weeks or even months on end.

Symptoms of Dog Colitis

Dog Colitis As mentioned above, colitis is an inflammation of the colon, and diarrheas related to the colon have some classic symptoms, as follows:

  • There is often mucus or fresh blood in the stool.
  • The stool often starts out normal and finishes loose.
  • The stool is soft or slimy rather than watery.
  • The dog very often strains when producing the stools and may continue to strain even after defecation.
  • The dog may exhibit a sense of sudden urgency to go to the bathroom.
  • Even with chronic colitis, the dog does not lose weight.

Other symptoms that may accompany diarrhea include:

  • Tender and/or distended abdomen.
  • Vomiting.
  • Dehydration (In the worst cases, this leads to collapse).

Causes of Dog Colitis

Identifying the underlying cause of colitis is extremely important because a treatment for one cause can frequently worsen colitis caused by a different disease.

Common causes of acute colitis include the following:

  • Eating inappropriate things, or consuming a meal of unfamiliar food. Rich foods, dairy products, or fatty foods are common causes of colitis in dogs.
  • Stress resulting from changes such as moving, or boarding - especially if the dog has a nervous disposition.

Sometimes the cause of colitis is unknown and the dog is said to be suffering from "idiopathic colitis".

Chronic colitis can be caused by the following:

  • Parasitic and Bacterial Infections

    Common parasites that cause colitis include whipworms and giardia. Bacterial infections that cause colitis include Salmonella, E coli, and Campylobacter. Though there is some overlap, parasitic infections usually arise from drinking contaminated water, and bacterial infections result from ingesting contaminated food.

  • Food Intolerance or Food Allergy

    Dog colitis can be caused by a food intolerance which may result from ingesting dyes, preservatives, contaminants or even some proteins in the food. Similarly, colitis can result from an actual food allergy, in which case a hypoallergenic diet containing a protein source which the dog has never had before (for example venison or rabbit), may be beneficial.

  • Inflammatory Bowel Disease (IBD)

    IBD is a serious disease characterized by an invasion of the colon walls by the body's own inflammatory cells (cells which normally fight infections). This leads to a persistent state of inflammation of the colon lining and a complete disruption of its normal functioning. Visit our page on Canine IBD for more information on this disease.

  • Irritable Bowel Syndrome (IBS)

    Many people mistakenly use IBD and IBS interchangeably. In fact, IBD and IBS are different. In IBS, there is no inflammation of the colon. IBS is a psychosomatic disease. This means that it is the activity of the mind that causes the symptoms. Essentially, the colon constricts much more than it should and the waste products are moved through at too fast a rate for the absorption of the water and nutrients. IBS is usually associated with neurological or psychological problems, e.g. a dog that is stressed or anxious.

  • Other Possible Causes

    In rare cases, colitis in dogs can be caused by foreign bodies and abrasive material in the gut, chronic pancreatitis, polyps, and cancer. There is also a form of colitis called histiocytic ulcerative colitis, aka "Boxer colitis" since young boxers are the dogs most predominantly affected by this.

Treating and Managing Dog Colitis

Like other diseases, colitis is best managed when its cause is known so that appropriate specific medication and therapy can be given. When this is not possible, such as when an immediate diagnosis of the underlying cause cannot be made, natural remedies and treatment can still be given to temporarily manage the symptoms.

Treating Acute Colitis

For an episode of acute colitis in dogs, usually a 24-48 hour fast is sufficient to manage the problem. Make sure that fresh, clean drinking water is available. After 24- 48 hours, introduce a bland, low-fat diet such as boiled chicken or white fish with rice. When symptoms of colitis subside, re-introduce the normal diet to your dog, gradually increasing the amount of food a little every day for about a week.

Treating Chronic Colitis

Chronic colitis in dogs can be treated by managing the symptoms using herbs, homeopathy, and dietary supplements.

Herbal and Homeopathic Remedies

Various herbs (e.g. slippery elm, marshmallow root, licorice) and homeopathic remedies can be used to alleviate symptoms of diarrhea. Visit our page on Canine Diarrhea Remedies for additional information.

Nutritional Supplements

Nutritional supplements are useful in treating chronic colitis. In particular, the following supplements should be given to your dog if he has chronic or repeated episodes of colitis:

  • Probiotics - Studies indicate that probiotics, or "friendly" bacteria, can help reduce symptoms of colitis by restoring the balance of microflora in the dog's intestinal tract.
  • Digestive Enzymes - Digestive enzymes can be used to aid proper digestion and absorption of nutrients.
  • L-Glutamine - It helps to protect the stomach and intestinal lining and also may prevent the formation of stomach ulcers.
  • N-Acetyl-Glucosamine - Research suggests that N-acetyl-glucosamine supplements may improve symptoms of inflammatory bowel disease.
  • Fructooligosaccharides (FOS) - FOS are carbohydrates made by combining two naturally occurring sugars, fructose and glucose. FOS are digested by the large intestine. They are believed to inhibit the growth of harmful bacteria and support the growth of healthy bacteria.
