best dog diarrhea solutions

No pet owner likes to talk about it, but we've all dealt with it. Diarrhea in dogs is very common because they tend to eat things that they aren't supposed to. Fortunately, it usually goes away on its own, so even the best dog diarrhea remedies should only be used in severe cases, and they will help to clear it up quickly.

A vet consultation is especially important when it comes to any other over-the-counter medicine or treatment for dogs, particularly before using any diarrhea remedies for dogs to make sure your pet needs it.

Diarrhea in dogs is a condition that varies in intensity, frequency and duration depending on the dog and the underlying cause of the diarrhea. Your vet will help you decide if using medicine for dog diarrhea or other aids and treatments are the best options or if it just needs to run its course.

What You Should Know About Diarrhea in Dogs

A dog's digestive system.
A dog's digestive system.

Have you ever wondered why your dog can eat things that would make you extremely ill? That is because dogs and humans digest food in a very different way, according to this study.

The shape of our jaws and teeth helps to break down food even before it hits our throats. The digestive enzymes in our mouths also work to begin breaking down food the minute it touches our tongue, but that's not how it works for dogs.

A dog's mouth is designed for tearing and shredding food, and the enzymes in their mouths work mostly to kill bacteria. Food also travels to their stomach much faster than ours, and their stomach acid is about three times stronger than ours.

In layman's terms, this means that our dogs can digest food that is still intact. A dog's natural instinct is to eat anything that smells appealing to them. Pair that food drive with a digestive tract that works especially quickly, and you've got a recipe for diarrhea.

In other words, it's usually difficult to 100% prevent diarrhea in dogs, and there are many foods and several factors that can trigger a dog's bout of diarrhea.

According to research (1, 2, 3, 4), some common causes of diarrhea in dogs include:

  • dietary indiscretion
  • change in diet
  • food allergies
  • stress
  • bacterial and other infections

Note that there may be many other causes of dog's diarrhea, including some of the more dangerous diseases like canine pancreatitis or canine parvovirus.

How to Treat Diarrhea in Dogs?

The below-mentioned best dog diarrhea remedies and solutions should not be your first response to treating diarrhea in dogs until you speak with a veterinarian and rule out any serious health problems. In very serious cases, antibiotics may be needed (5).

That said, for regular bouts of dog diarrhea, the best diarrhea treatments for dogs are:

  • Food deprivation
  • Monitoring of liquid intake and re-hydration
  • Adjustment and improvement of the dog's diet
  • Use of dog diarrhea remedies and digestive supplements

The “natural” way of treating diarrhea in dogs is just letting it run its course. However, because diarrhea in dogs may be a symptom of a vast number of underlying health conditions, it's best to speak with your vet if the condition lasts more than 48 hours.

There are several ways your vet will determine the cause of diarrhea in your dog:

The cause of small intestinal diarrhea may be determined from blood tests, examination of the stool, x-rays or ultrasound of the abdomen or by endoscopy.” – College of Veterinary Medicine at Washington State University (source)

You'll need to observe any other symptoms or changes in behavior and report those to your veterinarian. This will help your vet determine whether or not it will be safe to use one of the best dog diarrhea remedies or if more serious treatment is required.
