Are Probiotics Good for Senior Dogs?

Yes, probiotics for senior dogs are good. A senior dog’s health needs much more attention and care than dogs in other life stages.

A healthy gut and a strong immune system are imperative for older dogs. Probiotics can help with both. Here are some of the benefits of adding probiotics to your senior dog’s diet:

  • Better Digestion. The main function of a probiotic is to support food digestion. As dogs grow older, their digestion abilities decline, which compromises their gastric and intestinal health.
  • More Good Bacteria. Probiotics are essentially live cultures that support gut health. Probiotics increase the number of these beneficial bacteria in the digestive tract.
  • Strong Immune System. Incorporating probiotics in your senior dog’s daily diet will improve their immune strength and prevent them from getting sick often.
  • Improved Breath. Bad breath is a common issue among older dogs. Probiotics help manage the oral microbiome, thus supporting a fresh breath.
  • Other Benefits. Finally, probiotic supplements for senior dogs can also help with other issues such as food allergies and weight gain.

How Do You Know if Your Senior Dog Needs Probiotics?

Senior dogs in need of probiotics will show signs and symptoms a healthy dog is not experiencing. For example, dogs would benefit from a probiotic supplement in the following scenarios:

  • Frequent diarrhea or constipation
  • Undigested food in stool
  • Foul-smelling stools
  • Flatulence and/or burping
  • Tummy rumbling or gurgling
  • Abdominal cramping and pain.

Whether your dog has one or multiple symptoms, we recommend visiting a vet before switching to a probiotic-supplemented diet for your dog.

How Long Should I Give My Senior Dog Probiotics?

The duration of giving probiotic supplements varies depending on the senior dog‘s overall wellness and the underlying cause for using the product.

It could be daily for a month or two, depending on how fast your dog achieves the maximal health benefits of probiotics. We highly recommend consulting a veterinarian to understand the duration and daily dosage of the supplement for your dog’s digestive system.

What Kind of Probiotic Should I Give My Senior Dog?

The best probiotics for senior dogs are soil-based probiotics (SBOs). SBOs are strains of spore-forming bacteria that survive the journey through the dog‘s gut and reach the colon.

As dogs get older, the gut flora diminishes, and the diversity of the gut bacteria changes. These SBOs prevent good vs. bad bacteria imbalances and support digestive health.

The best soil-based probiotics for senior dog are:

  • Bacillus coagulans
  • Bacillus subtilis
  • Bacillus indicus

To boost the probiotics’ effect, combine them with high-quality prebiotics such as FOS (fructooligosaccharides) or inulin.

Honest Paws Pre+ Probiotics for Dogs
  • Specially formulated with both dog probiotics and prebiotics.
  • Avoid diarrhea, loss of appetite, constipation, and many other problems.
  • Helps promote the production of natural antibodies, fight free radicals, and support a healthy immune system in your dog.

What Should I Look for in Probiotics for Senior Dogs?

To ensure that your choice of probiotics for senior dogs is safe and effective for your senior dog, dog owners should keep the following things in mind:

  • Probiotic Strains. There are two considerations in this category. First, make sure that the bacterial strains are spore-forming. Second, ensure that several different bacterial strains can contribute to the diversity of the gut microbiome. Usually, five different strains are a choice.
  • Colony Forming Units (CFU). This refers to the number of microorganisms in the product. The more CFU in the supplement, the higher its potency. Which potency is best depends on the underlying reason for using probiotics for senior dogs.
  • Added Nutrients. The senior dog’s digestive system slows down and becomes less efficient with age. Therefore, it is a good idea to get a probiotic supplement enriched with digestion boosters such as digestive enzymes, prebiotics, antioxidants, vitamins, and minerals.
  • No Harmful Ingredients. Probiotics for senior dogs should be free from potentially harmful ingredients such as fillers, allergens, and artificial sweeteners.
  • Supplement Form. Probiotics for seniors come in different forms – from probiotic powders to chewable treats. If purchasing probiotic chews, ensure they are soft (senior dogs have trouble chewing on crunchy dog food).
