Is Bloody Diarrhea in Boston Terriers Normal?

Bloody diarrhea is not normal for Boston Terriers. Typically, if you notice bloody diarrhea, there is likely an underlying reason for it.

A Boston Terriers stool should be semi-firm and brown. If you notice any redness in the stool or if the stool is very soft or liquid, this is an abnormal finding.

Why Do Boston Terriers Get Blood in Their Stools?

There are several different reasons your Boston Terrier may be having bloody stools. This list includes eight of the most common causes of blood in the stool in Boston Terriers.

1. Intestinal Parasites

One of the most common causes of bloody diarrhea is intestinal parasites.

Even if you don’t see any worms in the stool, your Boston may still be infected with intestinal parasites. Intestinal parasites are often so small that you won’t always be able to see them in the stool.

Veterinarians can do a special fecal test to determine if your pet has intestinal parasites causing the blood in the stool.

The most common intestinal parasites in Bostons include:

  • Hookworms
  • Roundworms
  • Whipworms
  • Giardia
  • Coccidia

2. Stress Colitis

Has your dog been unusually stressed lately due to a recent move or schedule change?

Some Bostons may get stress colitis after a stressful event.

Stress colitis is a condition that causes inflammation in the large intestine and may also result in blood in the stool.

3. Dietary Indiscretion

Have you recently given a new type of treat, switched the diet, or has your Boston gotten into something they weren’t supposed to?

Dietary indiscretion occurs when your Boston eats something new, and it upsets their intestinal tract, potentially causing bloody diarrhea.

If you plan on changing foods, always remember to do so gradually over a 1 to 2 week period. A gradual food transition can help avoid bloody diarrhea from a diet change.

4. Hemorrhagic Gastroenteritis

Hemorrhagic gastroenteritis (HGE), also known as Acute Hemorrhagic Diarrhea Syndrome (AHDS), is a potential cause for bloody diarrhea in Boston Terriers.

This condition occurs most commonly in young, small breed dogs. The bloody diarrhea will often start suddenly and appear very bloody and watery.

HGE is a potentially life-threatening condition if not treated quickly. This condition can rapidly lead to dehydration, shock, and even death if not addressed by a veterinarian. 

If you suspect your Boston Terrier has HGE, you should contact your veterinarian as soon as possible.

5. Parvovirus

Parvovirus is a potential cause for bloody diarrhea, especially in Boston Terriers under one year of age or if your Boston has never been vaccinated for parvovirus.

Parvovirus is an intestinal virus that can cause severe vomiting and bloody diarrhea. Parvovirus is a severe infection that commonly causes death in puppies if left untreated.

It is essential to follow your veterinarian’s vaccine recommendations to ensure that your Boston is protected from parvovirus.

6. Inflammatory Bowel Disease

Inflammatory bowel disease is another cause of bloody diarrhea in Boston Terriers . This condition will often occur chronically or long term and could also cause weight loss or vomiting.

If your veterinarian suspects inflammatory bowel disease, special medications can be given to treat the symptoms of this disease.

7. Cancer

Rectal tumors and other intestinal cancers have the potential to cause bloody diarrhea.

If your Boston Terrier has bloody diarrhea, your veterinarian will likely do a rectal examination to ensure that no tumors are felt in the rectal area.

8. Anal Gland Abscess

If the stool seems to be mostly formed, but you notice blood on the stool or around the rectal area, this could be a sign of an anal gland abscess. 

If your Boston has an anal gland abscess, they may also lick a lot around the rectal area. Or you may notice a foul-smelling discharge around the rectal area.

Fortunately, anal gland abscesses are caused by an infection so they can often be successfully treated with antibiotics prescribed by your veterinarian.
