From dog parents

"Although the brush arrived later than I expected, I’ve been happy with it so far. Both of our golden retrievers seem to enjoy it, and it performs as promised."

- Kristen Maetzold · Verified Trustpilot review · Jan 27, 2026

"The ReNu grooming kit is essential for us! Our Bernese Mountain Dog, Gus, used to avoid brushing, but now he sits still and seems to enjoy it. His coat is incredibly soft and free of tangles!"

- Bernese Mountain Dog owner

"At last, a grooming product that really delivers! Our Black Lab, Buddy, sheds nonstop, but the FreshFur brush has made a big difference. He also loves the massage!"

- Black Lab owner

"I never expected grooming to feel pleasant for my anxious terrier, but the ReNu brush changed everything. It’s gentle, works well, and Lola loves it!"

- Anxious terrier owner

"Bailey used to scratch through the night during allergy season. Costly shampoos did not help. But this spray-and-brush pairing soothed her skin quickly, and we are finally sleeping again. Her coat looks shiny, and she no longer smells like chemicals."

- Bailey’s owner

"My anxious rescue usually refuses grooming, but this brush is so soft that she actually leans into it. The spray smells fresh, not medicinal, and her coat has never felt smoother. It’s now part of our weekly routine."

From cat parents

"I could not get my cat’s fur under control. Knots, shedding, and constant itching were the norm. We tried shampoos and detangling sprays, but nothing helped. Then we found the FreshFur brush and solution, and wow. It is so simple to use: fill, spray, and brush. Within days, his coat felt softer, looked smoother, and he stopped scratching nonstop. Best part? No stress or fuss."

- Long-haired cat owner

"We were spending $80+ each month on grooming to manage my cat’s shedding and itchy skin. This brush and spray combo gave better results at home. Her fur is finally shiny again and much easier to manage. Even our groomer asked what we were using."

- Multi-cat household

"Our cat’s paws were constantly itchy and flaky. We tried everything from special diets to vet meds. Brushing him daily with this tool and solution made a bigger difference than anything else. The shedding is lower, and the smell? Gone."

- Cat paw issues

For pets dealing with dry or cracked paws, our Soothing Paw & Claw Balm was made for exactly that.

From vets and professionals

"I’ve been a veterinarian for 9 years, and I suggest this to pet parents dealing with itchy skin or grooming anxiety. It is gentle, thoughtfully designed, and the results speak for themselves."

- Licensed veterinarian

"At our most recent vet visit, she asked what had changed — our dog’s coat looked shinier and healthier. We told her it was the FreshFur brush and misting spray. So simple, but so effective."

- From a vet visit

"A groomer permanently injured my pup, so ReNu lets us keep him clean and fresh-smelling without forcing him to stand on his leg for an extended period."

- Nadine Johnson · Verified Trustpilot review · Mar 1, 2026

Common questions from reviewers

Does FreshFur really help heavy shedders?

Yes. Many reviews come from owners of heavy-shedding breeds — Labs, Bernese Mountain Dogs, Golden Retrievers, long-haired cats — and the repeated feedback is a noticeable drop in loose fur after the first few uses. Visit our FAQ for more guidance on using it during shedding season.

Is it safe for anxious or injured pets?

Reviewers often mention that anxious rescues, nervous cats, injured dogs, and grooming-averse pets tolerate FreshFur better than traditional baths. The ultrasonic mist is nearly silent, and brushing does not require standing in a tub.

Do professional groomers use it?

Several reviewers say their own groomers have asked about FreshFur. Professionals often see the value in pH-balanced, sulfate-free formulas for upkeep between grooming appointments.
