PetLabCo.’s Probiotic Chew is one of our most-loved products – and the survey results show why:
PetLabCo.’s Probiotic Chew is made with probiotics, prebiotics, and postbiotics to help support your dog’s digestive comfort and immune health.
When given daily, you may notice signs of support like more regular stools, less paw licking, and a more comfortable tummy. It’s simple, tasty gut support, and a daily go-to for thousands of happy pups.
Brushing your dog’s teeth daily can be tricky, but supporting their oral health doesn’t have to be. PetLab Co.’s ProBright® Advanced is a daily dental powder that’s thoughtfully formulated with powerful ingredients to help support a clean mouth, fresher breath, and healthy gums. It’s used by thousands of pet parents across the country, and our survey results show why – after 90+ days of consistent use:
PetLabCo. ProBright Advanced is an easy-to-use daily dental supplement that features a patent-pending proprietary probiotic blend designed to support healthy oral bacteria levels, brown algae to help freshen breath, and sodium hexametaphosphate to target tartar build-up.
It’s loved by most dogs, easy to use, and fits seamlessly into your pup’s mealtime routine. Just scoop, sprinkle once a day, and see the potential results over time.
Seasonal sensitivities can be frustrating – for you and your dog. Our Allergy & Immune Chew is designed to support normal immune responses and help dogs stay comfortable during allergy season and beyond.
PetLabCo.’s Allergy & Immune Chew is designed to support your dog’s normal immune response and help maintain skin comfort – especially during allergy season. It’s made with a proprietary blend of probiotics that help maintain healthy canine gut flora, colostrum, which contains immune-supportive compounds, and a multiple-strain postbiotic that supports normal immune defenses.
When given daily, this tasty soft chew can help support immune function, seasonal comfort, and overall skin and coat health.
Your dog can’t say when something feels off – but subtle shifts in their digestion, behavior, or comfort may suggest their system could benefit from a little support.
That’s where PetLabCo.’s bestselling daily supplements come in. Whether it’s more regular stools, fresher breath, or less scratching, the benefits of giving our products can add up over time – helping your pup feel more comfortable, active, and at ease.
Daily health support can go a long way – helping your dog enjoy more tail wags, more zoomies, and more moments of everyday comfort.

Every dog is different, and their wellness needs can change with age, environment, and lifestyle. That’s why PetLabCo. offers a range of daily supplements designed to support key areas of your pup’s health, from digestive balance and immune health to oral care and seasonal comfort.
Still not sure? Check with your veterinarian to help choose the right option for your dog’s needs. And no matter which product you try, consistency is key – daily use over time helps give the ingredients to provide potential benefits.

Across all three products, over 90% of customers said giving the soft chews was easy from day one. That means less stress at supplement time, and more consistency – which is key to seeing results*. ² ⁸ ¹²
Every dog is different. While some dogs may show early signs of support in just a few weeks, most customers reported noticeable benefits after a few months of daily use. That’s why our survey focused specifically on pet parents who gave their dogs PetLabCo. products consistently for 90+ days – because consistency really matters. So stay patient, stay consistent, and trust the process. Every pup deserves to feel their best.
We’re so grateful to the pet parents who took the time to respond to our latest survey, and even more grateful that our products are becoming a meaningful part of so many daily routines.
From small changes like more regular digestive function or fresher breath, to fewer scratches and more relaxed pups, these stories remind us why we do what we do. Every wag, every happy nuzzle, and every quiet moment of comfort matters.
At PetLabCo., we believe wellness isn’t about dramatic overnight changes – it’s about the small, consistent signs that your dog is feeling good, inside and out. We’re proud to support dogs across the country with supplements that are loved by pups and trusted by pet parents.
