Symptoms

• Boxers are more susceptible to colitis than other breeds.
  
  Most dogs with colitis feel well and behave normally. They will have mucous and/or streaks of blood in their feces. If untreated, however, your dog may lose weight, become lethargic, and develop fever and abdominal pain.
  
  

Causes

• Chronic colitis can be caused by bacteria, parasites, food allergies or colon spasms. Acute colitis can be brought on by stress, parasites, a dietary indiscretion or a sudden change in diet.
  
  

Risks

• Typically colitis does not pose a great risk, as long as the correct treatment is prescribed and followed. If deep ulceration has developed, the situation is more serious.
  
  

Diagnosis

• Your veterinarian will perform a rectal exam, a fecal exam and a biopsy of the colon wall to determine the exact cause of your dog's colitis.
  
  

Treatment for Acute Colitis

• A bland diet could be prescribed.
  
  Acute colitis can usually be cleared up in 10 to 14 days. Typically, your veterinarian will prescribe an anti-inflammatory drug and a short-term bland diet. If a bacterial infection is present, an antibiotic will be in order.
  
  

Treatment for Chronic Colitis

• If colitis has become an ongoing problem for your dog, it will need to be constantly managed. Your veterinarian may suggest a prescription diet. Anti-inflammatory drugs, sulfa drugs and steroids are also used to manage chronic colitis.
