Each product is vet-reviewed and formulated to support dogs' everyday needs, offering targeted benefits across four key areas of health including gut health, dental hygiene including bad breath, mobility, and seasonal allergies:

• PetLabCo.^® Tailored Probiotic Chew: the tailored dog gut health supplement is clinically studied** and supports gut health, normal stools, and seasonal allergy discomfort, all in one daily soft chew. Plus, this probiotic for dogs is the company's flagship product, with over 11 million tubs of the standard Probiotic Chew product sold within the USA to date.
• PetLabCo.^® ProBright^® dog teeth cleaning powder: the unique, easy-to-use dog dental powder combines probiotics, brown algae and sodium hexametaphosphate, to help target tartar build-up, support gum health, and freshen breath.
• PetLabCo.^® Joint Care Chew Advanced: the salmon-flavored joint supplement for dogs has been carefully crafted to deliver advanced support for joint comfort, flexibility, and mobility at every lifestage.
• PetLabCo.^® Tailored Allergy & Immune Probiotic Chews: this dog seasonal allergy soft chew targets seasonal allergy discomfort at the source by combining probiotics with prebiotics, postbiotics, colostrum and total omega fatty acids, to help support normal immune defenses, skin and coat health.

The increased retail availability reflects growing consumer demand for functional pet wellness solutions, building on the company's strong growth following its majority stake investment from BC Partners in early 2025.
