Meta Description: Searching for honest PetLab Co. reviews? We tested the probiotic chews, joint care, and dental formula. Read our in-depth PetLab Co. review to see if these dog supplements deliver real results.

Introduction: The Moment I Realized My Dog Needed More Than Just Food

It was 3 AM, and I was lying on the cold kitchen floor, gently rubbing my senior Labrador’s stiff hips. He looked up at me with those big, trusting eyes—the same eyes that had greeted me every morning for 12 years. But lately, getting up in the morning had become a struggle. The arthritis was winning.

That night, I started googling frantically. PetLab Co. kept appearing in my searches. Then PetLab Co. reviews. Then PetLab Co. probiotic chew. Then PetLab Co. joint care. I fell down a rabbit hole of PetLab probiotics, PetLab Co. dental formula, and PetLab Co. allergy and immune products.

Like millions of pet parents, I was desperate for something—anything—that could give my best friend a better quality of life.

What I discovered changed everything. And now, I’m sharing my honest PetLab Co. review with you.

What Is PetLab Co.? The Story Behind the Brand

PetLab Co. (also known as the PetLab Co., Pet Lab Co., or thepetlabco) isn’t just another pet supplement company. It was born from heartbreak.

Co-founders Chris and Damian launched PetLab Co. in 2021—but the idea started years earlier. Chris had to make the devastating decision to put his 17-year-old dog to sleep. She had suffered from arthritic pain for the last four years of her life.

“I felt a lot of guilt around whether I could have done more in terms of supplementation to support her properly.” — Chris, Co-founder of PetLab Co.

That guilt became fuel. Chris and his co-founder Damian—whose dog Zeeko serves as the company’s official “CTO” (Chief Tasting Officer!)—set out to create science-backed supplements that actually work.

Today, PetLab Co. has grown into a global brand with over 4.5 million pet parents in their community. The company holds certifications from the National Animal Supplement Council (NASC) and NSF for Good Manufacturing Practices (GMP). In 2026, private equity firm BC Partners acquired a majority stake in the company—a testament to its rapid growth and market position.

PetLab Co. operates globally with headquarters in London and a presence in the US through subsidiaries. Their products are manufactured in the USA using high-quality, locally and globally sourced ingredients.

PetLab Co. Product Line: A Complete Breakdown

PetLab Co. offers a comprehensive range of dog supplements targeting specific health concerns. Here’s what you need to know about each:

1. PetLab Co. Probiotic Chews (The Flagship Product)

The PetLab Co. probiotic chew is arguably the brand’s most popular product. These pork-flavored soft chews are designed to support:

• Gut health and digestion

• Skin condition and coat health

• Immune function

• Seasonal allergy response

What’s inside: The PetLab Co. probiotic formula contains a proprietary blend of three spore-forming probiotic strains (Bacillus coagulans, B. clausii, B. subtilis), plus prebiotics and postbiotics. The spore-forming strains have a natural coating that helps them survive stomach acid and reach the gut where they provide benefits.

Dosage:

• Under 25 lbs: 1 chew daily

• 25-75 lbs: 2 chews daily

• Over 75 lbs: 3 chews daily

How long to see results: Some dogs show improvement within month 1, while others see best results from months 2 and 3 onward. Up to 90 days of consistent use may be needed for full benefits.

PetLab Co. probiotic reviews consistently praise the product’s palatability. One verified customer wrote: “My boy, Riley, eats these chews without a problem! He’s not scratching nearly as much.”

2. PetLab Co. Joint Care Chews

The PetLab Co. joint care chew was the company’s first product—and for good reason. Chris’s personal experience with his aging dog’s arthritis inspired this formulation.

Key ingredients:

• Glucosamine HCl – supports joint lubrication and healthy friction

• Green-Lipped Mussel – rich in natural joint-supporting compounds

• Turmeric (Curcugen®) – natural anti-inflammatory

• Boswellia – supports joint comfort

• Anchovy oil / Salmon oil – omega fatty acids for joint flexibility

PetLab Co. joint care reviews from customers report less stiffness, more restful sleep, and higher activity levels in dogs after starting these supplements. One eBay reviewer said: “I’ve been giving my dogs this for many years now and it’s been a massive help to the arthritis in their joints.”

3. PetLab Co. Dental Formula

The PetLab Co. dental formula (also known as ProBright® Advanced) is a daily dental powder supplement added to your dog’s food or water.

What it does:

• Targets tartar build-up

• Supports fresher breath

• Promotes whiter teeth

Key takeaway: The PetLab Co. dental formula works best when used consistently alongside regular tooth brushing and routine veterinary care. Results can vary—some users report noticeable improvements within a week, while others need more time.

With over 13,000 customer reviews on Trustpilot, PetLab Co. maintains an overall rating of “Great”.

4. PetLab Co. Allergy & Immune Chews

For dogs suffering from seasonal allergies, paw licking, and intermittent itchiness, PetLab Co.’s Allergy & Immune chews offer targeted support.

Key ingredients:

• Proprietary probiotic blend (Bacillus coagulans, B. clausii, B. subtilis)

• Colostrum (bovine) for immune support

• Krill oil (Omega 3, EPA, DHA)

• Fructooligosaccharides (prebiotics)

One reviewer shared: “I purchased an allergy chew for my dog… Almost all ****** is gone on my little Havanese fur baby.”The product has 4.4 out of 5 stars based on more than 2,000 reviews.

5. PetLab Co. Itch Relief Chews

The PetLab Co. itch relief chew targets dry, occasionally itchy skin and coats.

Key ingredients:

• Turmeric

• Omega 3 & 6 fatty acids

• Honey

• Quercetin (natural antihistamine)

• Astaxanthin (powerful antioxidant)

Customer experiences vary significantly. Some report great results: “This product is so effective! My dog itches so much and it has helped him.”Others haven’t seen improvement: “I was buying them for my dog that is constantly itching… after two months of this product, she had no relief.”

My dogs take the probiotics and the dental powder. I’ve definitely seen improved gut health with this. My dog who was always licking his paws, no longer does it.”

The Concerns (Negative Reviews & Complaints)

No PetLab Co. review would be complete without addressing the criticisms:

Price: This is the most common complaint. PetLab Co. products are among the most expensive on the market. One reviewer noted: “It’s too pricey for only 30 chews… especially when it says give 2 to 3 a DAY AND I have more than 1 dog.”

Subscription issues: Some customers report unexpected subscription charges. The BBB shows 126 total complaints over the last 3 years, with 56 complaints in the last 12 months. However, many of these appear to be related to subscription management rather than product quality.

Variable results: As with any supplement, results vary. Some dogs see dramatic improvement; others see none. One reviewer warned: “Buyers beware – This product doesn’t work.”

Dental formula concerns: A small number of users reported coughing in their dogs after using the dental water additive. Always consult your vet before starting any new supplement.

Final Verdict: Is PetLab Co. Worth It?

After hours of research, reading hundreds of PetLab Co. reviews, and understanding the science behind their products, here’s my honest take:

PetLab Co. is a premium, science-backed pet supplement brand that delivers on its promises for many dogs. The formulations are vet-informed, the ingredients are high-quality, and the company has earned legitimate industry certifications.

The Pros:

• Science-backed, vet-formulated products

• Dogs genuinely love the taste

• Real results for many customers (improved digestion, less itching, better mobility)

• NASC certified and GMP compliant

• 30-day money-back guarantee

My recommendation: If your dog has specific health concerns—digestive issues, joint pain, allergies, or dental problems—PetLab Co. is worth trying. Start with a one-time purchase (not a subscription) to test results. Be consistent for at least 60-90 days. And always, always consult your veterinarian first.

Because at the end of the day, our dogs give us their unconditional love every single day. They deserve the best we can give them.
