Are PetLab Co.’s Probiotic Chews Worth It? A Vet’s Perspective

PetLab Co.’s Probiotic Chews are designed with canine wellness in mind, aiming to support gut health, skin condition, and immune function. If you’re wondering what probiotics are good for dogs, and whether to give a probiotic a try, then these popular soft chews could be worth a look. They’re packed with three spore-forming probiotic strains, prebiotics, and postbiotics, but do PetLab Co. Probiotic Chews live up to the hype?

PetLab Co. has partnered with veterinarians and pet nutrition experts to ensure that pet parents have the information they need when deciding whether to try Probiotic Chews for their furry companions. In this article, you’ll find a vet-informed breakdown of the science behind probiotics for dogs, how PetLab Co.’s formula stacks up, and what makes it one of the most trusted probiotic options in the U.S.

What Probiotics Are Good for Dogs?

Your dog’s digestive system is home to a unique community of microscopic organisms known as the gut microbiome. This delicate ecosystem is shaped by many factors, including your dog’s diet, environment, and genetics.                                             

When the balance of good and bad bacteria in the gut gets disrupted, your dog may show signs like loose stools, or other responses that may be linked to changes in immune, skin, or behavioral function. 

That’s where probiotics come in. Probiotics for dogs are live bacteria and yeasts that may provide health benefits for your dog by helping to maintain the balance of organisms in their gut microbiome. 

When selecting a probiotic for your dog, you may also come across the term “prebiotics”. While probiotics are the live organisms contained in the product, prebiotics are the fiber upon which the organisms feed. It is best to select a product that contains both probiotics and prebiotics. d and manufactured in the USA, utilizing high-quality, locally and globally sourced ingredients.

Consistency is recommended. Long-term use is important to provide consistent support of the gut microbiome and its impacts on the immune system and behavior.
