"While the brush took longer to arrive than I expected, so far I have been pleased with the product. Both of our golden retrievers seem to love it and it does work as promised."
- Kristen Maetzold · Verified Trustpilot review · Jan 27, 2026
"The ReNu grooming kit is a must-have! Our Bernese Mountain Dog, Gus, used to run from the brush, but now he sits and enjoys it. His coat is so soft and tangle-free!"
- Bernese Mountain Dog owner
"Finally, a grooming product that actually works! Our Black Lab, Buddy, sheds like crazy, but the FreshFur brush has made a huge difference. Plus, he loves the massage!"
- Black Lab owner
"I never thought grooming could be enjoyable for my anxious terrier, but the ReNu brush is a game-changer. It's gentle, effective, and Lola loves it!"
- Anxious terrier owner
"Bailey used to scratch all night during allergy season. None of the expensive shampoos worked. But this spray and brush combo calmed her skin right away, and we're finally sleeping again. Her coat looks glossy, and she doesn't smell like chemicals anymore."
- Bailey's owner
"My anxious rescue usually hates grooming, but this brush is so gentle she actually leans into it. The spray smells clean, not medicinal, and her coat has never felt softer. It's become part of our weekly routine now."
- Anxious rescue owner

"I couldn't get my cat's fur under control. Knots, shedding, and constant itching. We tried shampoos and detangling sprays but nothing helped. Then we found the FreshFur brush and solution, and wow. It's so easy to use: just fill, spray, and brush. Within days, his coat was softer, smoother, and he stopped scratching nonstop. Best part? No stress or fuss."
- Long-haired cat owner
"We were paying $80+ a month for grooming to deal with my cat's shedding and itchy skin. This brush and spray combo gave better results at home. Her fur is finally shiny again and so easy to manage. Even our groomer asked what we were using."
- Multi-cat household
"Our cat's paws were always itchy and flaky. We tried everything from special diets to vet meds. But brushing him daily with this tool and solution made a bigger difference than anything else. The shedding is down, and the smell? Gone."
- Cat paw issues
For pets with dry or cracked paws, our Soothing Paw & Claw Balm is made for exactly this.
"I've been a veterinarian for 9 years and I recommend this to any pet parent dealing with itchy skin or grooming anxiety. It's gentle, smartly designed, and the results speak for themselves."
- Licensed veterinarian
"At our last vet visit, she asked what we changed - our dog's coat looked shinier and healthier. We told her: it's the FreshFur brush and misting spray. So simple, but so effective."
- From a vet visit
"Groomer permanently injured my pups so ReNu allows us to get him clean and fresh-smelling without making him stand on his leg for an extended period."

Learn more about the research behind our formula on our Backed By Science page.
Yes. Most reviews come from owners of heavy-shedding breeds - Labs, Bernese Mountain Dogs, Golden Retrievers, long-haired cats - and the consistent feedback is a noticeable reduction in loose fur after the first few uses. See our FAQ for more on using it during shedding season.
Reviewers repeatedly mention that anxious rescues, nervous cats, injured dogs, and grooming-averse pets tolerate FreshFur better than traditional baths. The ultrasonic mist is almost silent, and brushing requires no standing in a tub.
Multiple reviewers note that their own groomers have asked about FreshFur. Professionals tend to recognize the value of pH-balanced, sulfate-free formulas for between-grooming maintenance.
