PetLab Co. Reviews 2026: Are These Probiotic Chews & Supplements Worth It for Your Dog?
Meta Description: Read our honest PetLab Co. reviews covering probiotic chews, joint care, and dental formula. See if these vet-reviewed supplements actually work for dogs before you buy.
The 4 AM Wake-Up Call That Changed Everything
It was 4:17 AM. My 11-year-old Labrador, Max, was pacing the bedroom floor, unable to settle. His joints were stiff, his breath was terrible, and he’d been scratching his ears raw for weeks.
I’d tried everything—expensive vet visits, prescription medications, endless trips to the pet store for “miracle” products that never delivered. Nothing worked.
Then a friend mentioned PetLab Co. I was skeptical. Another pet supplement brand making big promises? I’d heard it all before.
But something felt different this time. Maybe it was the desperation in my own voice. Maybe it was the way Max looked at me with those tired eyes, asking for help.
So I did what any pet parent would do—I dove deep into PetLab Co. reviews, analyzed every product, and put their supplements to the test.
What I discovered shocked me.
What Exactly Is PetLab Co.?
PetLab Co. is a rapidly growing pet supplement brand headquartered in London, founded in 2018 by Chris Masanto and Damian. The company was born from a heartbreaking personal experience—Masanto’s own dog suffered from arthritic pain for four years before passing away at 17.
“I felt a lot of guilt around whether I could have done more in terms of supplementation to support her properly,” Masanto shared.
That guilt became fuel. Today, PetLab Co. has impacted the lives of over 4 million dogs worldwide and earned recognition from industry bodies including the National Animal Supplement Council (NASC) and NSF for Good Manufacturing Practices (GMP).
In February 2025, BC Partners—the investment firm behind Chewy, PetSmart, and VetPartners—acquired a majority stake in the company, signaling serious confidence in the brand’s trajectory.
But here’s the question every pet parent wants answered: Do the products actually work?
The Product Lineup: What PetLab Co. Offers
PetLab Co. specializes in vet-reviewed supplements targeting specific health concerns. Let’s break down their core offerings.
🐾 PetLab Co. Probiotic Chews
The PetLab Co. probiotic chew is arguably their flagship product—and for good reason. These pork-flavored soft chews contain 8 strains of probiotics designed to support digestive health, immune function, and skin condition.
What customers say:
- “I have been using probiotic chews for over 2 years. I have a healthy dog. No vomiting, diarrhea, or scratching.” — Deborah
- “Our black lab Tilly now has a healthier gut and coat. She hasn’t had issues with her ears since she started taking the probiotic.” — Angela
- “My dog’s seasonal allergies improved big time and she is not licking her paws anymore.” — Jenna
Common themes in PetLab Co. probiotic chew reviews:
- Noticeable improvements in digestion and stool consistency
- Reduced scratching and paw licking
- Enhanced skin and coat appearance
- Dogs genuinely enjoy the taste (even picky eaters!)
🦴 PetLab Co. Joint Care Chews
Joint issues are one of the most common problems aging dogs face. The PetLab Co. joint care chew was actually the company’s very first product, developed to address co-founder Chris Masanto’s personal pain point.
What customers say:
- “A very good joint product. I have a senior dog and he will eat these without any problems. He is happy and eager to get going again.”
- “I’ve been giving my dogs this for many years now and it’s been a massive help to the arthritis in their joints.”
The PetLab Co. joint care chew reviews consistently highlight improved mobility, reduced stiffness, and dogs showing more energy during walks.
🦷 PetLab Co. Dental Formula
Dental health is often overlooked, but it’s critical for overall wellness. PetLab Co. dental formula comes as a water additive, making it incredibly easy to use.
What customers say:
- “Within a week, his teeth were noticeably whiter and his breath fresher.”
- “Really good and easy solution to keep dog’s teeth clean. They don’t seem to notice difference in the taste of water and clean tart build up within the first week.”
- “This product is easy to use, works well to inhibit bad breath and tartar, has no odor of it’s own, and does not seem to have any flavor that my dog would not like.”
🌿 PetLab Co. Allergy & Immune Chews
Seasonal allergies affect countless dogs, manifesting as itchy skin, ear infections, and excessive scratching. The PetLab Co. allergy and immune chews are formulated to support immune function and help keep occasional allergies at bay.
With 4.4 out of 5 stars based on more than 2,000 reviews, this product has clearly resonated with pet parents.
