New York – October 28, 2026 -- Dog owners can now pick up PetLabCo.'s probiotic chews, dental powder and joint supplement in person at all 1,500+ PetSmart stores across the U.S.
Four products now sit on PetSmart shelves
The retail rollout covers the Tailored Probiotic Chews, ProBright dental powder, Joint Care Chew Advanced and Tailored Allergy & Immune Probiotic Chews. Each is vet-reviewed and aimed at one of four areas: gut health, dental hygiene including bad breath, mobility, and seasonal allergies.
The flagship chew has sold over 11 million tubs
The Tailored Probiotic Chew is a daily soft chew that supports gut health, normal stools and seasonal allergy discomfort. The company says more than 11 million tubs of the standard Probiotic Chew have sold in the U.S. to date. A 31-day clinical study showed that daily use enhances beneficial gut bacteria. The company also says it was the No. 1 selling probiotic soft chew in the Dog Probiotics Supplements category on Amazon, year to date as of May 20, 2026.
Dental, joint and allergy options round out the lineup
- ProBright dental powder: combines probiotics, brown algae and sodium hexametaphosphate to target tartar build-up, support gum health and freshen breath.
- Joint Care Chew Advanced: a salmon-flavored chew for joint comfort, flexibility and mobility at every life stage.
- Tailored Allergy & Immune Probiotic Chews: pair probiotics with prebiotics, postbiotics, colostrum and total omega fatty acids to support normal immune defenses, skin and coat health.
Growth followed a 2025 investment
PetLabCo. says the move builds on strong growth after BC Partners took a majority stake in early 2025. The brand counts 5 million U.S. customers and over 100,000 5-star ratings and reviews globally.
CEO and co-founder Chris Masanto said the PetSmart expansion lets the company serve more pet parents across America.
