PetLab Co. Probiotic Chews vs Pet Honesty Gut + Immune Health

PetLab Co. and Pet Honesty are both direct-to-consumer subscription chews, and listicles covering 'best probiotic chews for dogs' routinely put them side by side. Both are labeled at 3 billion CFU per serving, so this pair is a clean case where the CFU number alone tells you nothing, it's identical on both labels. The real split is strain count and research depth: Pet Honesty lists 8 strains against PetLab Co.'s 3, while PetLab Co. shows one more canine RCT on record, 3 versus 2.

Stronger value rule: more strain-named organisms, CFU guaranteed through expiry over at-manufacture, and more canine RCTs each count as stronger. Raw CFU count alone never does.

Asked about this pair

Can you give a dog both of these?

We have no forum data for this pairing to check against, and both products carry the same 3 billion CFU per serving, so combining them would roughly double the CFU exposure without any added research behind the combination. Ask your vet before stacking two probiotics.

Both list 3 billion CFU. Does that mean they're basically the same product?

No. Identical CFU counts don't mean identical formulas. Pet Honesty's edge is strain count (8 versus 3); PetLab Co.'s edge is canine RCT count (3 versus 2). The CFU figure being tied is exactly why it shouldn't be the deciding factor here.

Are both available on Amazon?

Yes. PetLab Co. Probiotic Chews (B089XVJHFK) and Pet Honesty Probiotics Gut + Immune Health Soft Chews (B07D3Z6ZVC) both have an ASIN on record.
