What Are Probiotics for Dogs?

As we mentioned, probiotics are friendly or helpful bacteria. Your dog’s gastrointestinal system has countless bacteria to help digest food. Most of the bacteria in your dog’s system are beneficial, although some of them are inevitably harmful. When your dog is healthy, active, and feeling good, it’s estimated that he will normally have about 80 percent beneficial bacteria and 20 percent harmful bacteria in his system.

However, it’s easy for a dog’s system to get out of balance. If your dog is stressed by traveling, by eating something noxious, by changing foods, by traveling, or by taking antibiotics or other prescription medications, the good bacteria in his digestive system can be wiped out or overtaken by the bad bacteria.

Then you have a dog with diarrhea or other health problems. Antibiotics, in particular, are known for killing off all of the microorganisms in a dog’s digestive system. Their very name, “antibiotics, means that they will kill off living organisms. Your dog can be left with a few microorganisms, but they can be the most harmful ones.

Yogurt and kefir are natural probiotics. Dogs can benefit from small amounts of these foods added to their daily diet. Or, you can purchase a probiotic that’s made for dogs.

Zesty Paws Core Elements Probiotic Pumpkin Flavored Soft Chews Digestive Supplement for Dogs

Pros
  • Contains three billion CFUs per chew;
  • Contains six strains of friendly bacteria.

Cons
  • Made with pea flour and garbanzo flour – ingredients that are included in the FDA warning about grain free foods for dogs, though in these small amounts they probably won’t make a difference;

This is a powerful strain of Bacillus Coagulans that gets past your dog’s stomach acid to reach the intestines and promote healthy digestion and gut bacteria. These chews feature papaya to help with indigestion and to provide enzyme support. Papaya can help the stomach break down proteins and fats. Suitable for dogs of all ages.

Probiotics or Prebiotics?

Probiotics are bacteria. Live bacteria in the form of microorganisms are given to the dog (or human, cat, or farm animal), and there are benefits to the digestive system, immune system, and other parts of the body.

According to the World Health Organization (WHO), probiotics are “live microorganisms, which, when administered in adequate amounts, confer a health benefit on the host.”

Prebiotics are something else. First, they are not digestible or only poorly digestible, even though they are edible. They are nutrients that stimulate the growth of the microflora in the digestive tract. They are usually carbs and fibers. You probably eat many prebiotic foods every day without realizing it.

Bananas and apples, for example, are natural prebiotics.

You may also see something called fructooligosaccharides (FOS) listed in your dog food’s ingredients. This is a natural sugar that is often used as a prebiotic.

What Are the Benefits of Probiotics for Dogs?

Probiotics can improve digestion and help dogs with issues like irritable bowel disorders and diarrhea. A study in Ireland found that dogs supplemented with a strain of Bifidobacterium animalis shortened their diarrhea experience from seven days to four and eliminated the need for antibiotic treatment by about 10%.

Probiotics are ideal for dogs under stress, after antibiotics, those with food allergies, sensitivities, digestive problems, older dogs, weakened immune systems, and young puppies.

Most dogs can benefit from probiotics, but there is limited research on humans and probiotics. More research is being conducted by companies like Purina. It is unclear whether dogs can benefit more from a probiotic with one or multiple strains of bacteria.

While more research supports one strain, some researchers prefer the idea of giving dogs multiple strains of a probiotic. Future research will provide more information on the benefits of probiotics for dogs.

Can You Give Your Dog Probiotics Made for Humans?

Many veterinarians and others will recommend that you give your dog probiotics that are made for humans, such as Culturelle and other products. PetMD.com says that there are no studies that show human probiotic supplements will harm your dog.

However, that site, which is written and reviewed by vets, recommends that you use a probiotic product with strains that your dog’s gut specifically needs.

Some veterinarians use human probiotics for their animals because they say that human products have better quality control.

Whether you give your dog a probiotic made for humans appears to be a personal decision right now.

Which Dog Probiotics Does Your Dog Need?

Common bacterial strains that are usually provided for dogs in probiotics include:

  • Enterococcus faecium
  • Lactobacillus acidophilus
  • Lactobacillus casei
  • Lactobacillus plantarum
  • Bifidobacterium bifidum
  • Bifidobacterium animalis
  • VSL#3

Some of these strains often appear on dog food labels. You can look for probiotic products that contain them.

Choosing Probiotics for Dogs

• Ensure products are fresh to retain living organisms in the dog’s digestive system.
• Check the “Best By” or “Sell By” date for product availability.
• Select products with high CFU (colony-forming units) for a healthy gut.
• Choose the appropriate form of probiotic, such as powder, pill, or mixed with treats.
• Look for a label from the National Animal Supplement Council (NASC) for safer products.

Final Thoughts

Many dogs have benefited from taking probiotics for both short-term and long-term health. If your dog has an issue with diarrhea or gas, or if he’s taking antibiotics or feeling stressed for some reason, we think that probiotics are a good way to help your dog recover and feel better. There are a variety of brands on the market.
