“We are starting to understand how probiotics actually work, so we are discovering now a days that certain types of probiotics can be useful for certain conditions,” said veterinarian Dr. Jan Suchodolski.

Experts say so far studies have shown probiotics seem to help pets who have stressed out stomach problems. Dr. Korinn Saker, a clinical veterinary nutritionist, ran studies on dogs in animal shelters who had GI upset.

“We found was that the animals, the dogs that were put on the probiotic, actually resolved faster and improved to a more significant and greater degree than those animals that were put on a traditional antibiotic,” Saker explained.

Studies to uncover what other animal ailments probiotics may help are ongoing.

However, researchers have learned that not all pet probiotic products measure up to their ingredient claims. One study tested 15 probiotic supplements, and only four met or exceeded the product’s label claim for the amount of “viable organisms” or good bacteria.

“In order to have probiotic effect we need to have a product that contains live microorganisms and also should probably have in a very high amount of bacteria industrially its very challenging to manufacturer it,” said Suchodolski.

Experts say you if you’re considering using probiotics for your pet, talk to your vet about which brands and kinds may be beneficial. But, do your otherwise happy and healthy pets really need them?

“I think running to the store and purchasing probiotics is probably not the best use of your dollar,” said Saker.

Piro however says the money she’s spent has been worth every dollar.

“I think now we’re giving pets the same advantage that we’ve used in humans for years,” she added.
