Why is my dog’s stool loose?

There are many reasons that your dog may be having loose stool. These are a few of the most common reasons for a dog to have diarrhea and what you can do about them.

Poor Diet

Dog's not eating a proper diet can have diarrhea. A poor-quality dog food often leads to diarrhea as this type of food has fillers and unwanted by-products.

GI Tract Issues

Some issues of diarrhea are due to a problem with the gastrointestinal tract.

Food allergies

While not a common cause of allergies, food allergies can cause a dog to have diarrhea. Most dogs with food allergies are allergic to beef or chicken. Switching to a different type of protein that the dog has never had before such as rabbit or duck is best.

Food intolerance

Food intolerance is when your dog’s gastrointestinal tract can not properly break down the food and absorb the water. This can cause very severe and even uncontrollable diarrhea.

Infection

Gastroenteritis is an infection of the intestinal tract. Once the infection sets in, the body's way of getting rid of the infection is by forcing the bacteria out of the body. This can lead to diarrhea.

Parasite

Certain parasites such as hookworms, roundworms, and whipworms, can cause diarrhea in pets. This can be easily treated with a dewormer you can get from your veterinarian. Not all parasites are visible without a microscope. If you think your dog could have parasites, taking a fecal sample to your veterinary office. They will make sure that the medication you are using to treat the worms will address the worms that your pet has.

Food Poisoning

Just like with people, dogs can also get food poisoning. They can eat a bad bag of dog food that contains molds or get into old leftovers in the trash. All of these can cause diarrhea in your dog. Usually, they will then need some antibiotics to clear up the infection causing diarrhea.

Illness

Some illnesses can also cause diarrhea, along with other signs of the disease.

Kidney or liver disease

Colitis

Cancer

Cancer may at first show up as just diarrhea, but internally something more serious is going on. Dogs who suffer from cancer will usually have periods of diarrhea.
