Top 10 Reasons Your Dog Has Diarrhea and When to Worry


When your beloved pooch comes down with a bout of diarrhea, it can certainly make life miserable for both of you. Many mild cases of diarrhea may resolve on their own, but others may be indicative of a more serious condition that requires treatment by your vet.

If diarrhea lasts longer than 24 hours, is accompanied by additional worrisome symptoms such as a change in behavior, lethargy, vomiting, or reduced appetite; or if the diarrhea is black, tarry, or contains large amounts of blood, you should schedule an appointment with your veterinarian as soon as possible. Very young or old dogs, or dogs with pre-existing health conditions, should always be seen for cases of diarrhea — they’re much more likely to develop complications.

Wondering why your pup is suffering from belly troubles, and what you should do about it?

Here are the top 10 causes of diarrhea in dogs.

1#1 Viruses

Gastrointestinal viruses are most commonly seen in puppies and young dogs, but can affect dogs of any age. Viruses are generally passed to your dog through direct contact with a sick animal or from contaminated fecal material.

Many viruses are mild and will resolve on their own, however serious infections like parvovirus are a life-threatening emergency and need to be treated as such. Dogs with parvovirus can often be identified by their frequent severe bloody diarrhea, loss of appetite, lethargy, and fever. If your dog is not vaccinated for parvovirus and exhibiting any of the above symptoms, call your veterinarian immediately.
