What causes of colitis in dogs?
Colitis in dogs comes in two types.
Acute colitis can be caused by the dog eating something that disagrees with them, for example having eaten a large amount of grass or raided the rubbish bins or countertops to find some unsuitable food. A stressful situation can cause a digestive upset. Infections, either parasitic such as worms or with bacterial causes like Campylobacter, Salmonella or E. coli can also cause acute colitis.
Chronic colitis involves the dog having constant or repeated symptoms. This can be due to a number of causes. Irritable Bowel Syndrome is one potential. There are a number of dog breeds prone to colitis, and Inflammatory Bowel Disease is a common implication in chronic colitis. These breeds include French Bulldogs, Miniature Schnauzers, West Highland Terriers, Pugs and German Shepherds. Trauma can cause chronic colitis, possibly as damage from previous parasitic or bacterial infections, which can interfere with the gut’s ability to properly digest food and so lead to diarrhoea. Immune conditions such as Inflammatory Bowel Disease can cause the dog’s immune system mistakenly to see normal cells as foreign invaders and attack its own colon lining. Food allergies prompt an immune system response as the body recognises a dangerous substance and attempts to rid the body of the danger by causing nausea, vomiting and diarrhoea. Food intolerances present as an inability to digest the problem food properly, which makes the dog very uncomfortable with symptoms of bloating and abdominal discomfort along with the diarrhoea.
