Our Mission, Led by Nora Mitchell, Founded With Love for Pets
At ReNu, our mission is simple: to make grooming calmer, kinder, and better for every pet.
Founded by Nora, a passionate pet parent, ReNu was created to solve the daily struggles we all face — shedding, stress, and grooming battles that make bath time harder than it should be.
With the help of trusted veterinary partners like Dr. Renu Ramesh, Nora turned this mission into a product that truly works: a grooming tool that relaxes pets, improves coat health, and strengthens the bond between you and your best friend.

Our grooming products are proudly crafted in Denver, Colorado, in a GMP-certified facility that adheres to the highest safety and quality standards.
FreshFur is designed to be gentle for everyday use. Most pets tolerate it well, but every pet is different. If your pet has known sensitivities, we recommend starting with a small area first and adjusting use based on your pet’s comfort.
You’ll notice results right away as you brush — loose fur, dirt, and debris lift away instantly. Results may vary depending on coat type and how dirty your pet is, but most customers see a difference during the first use.
Using FreshFur is simple:
- Add FreshFur Cleansing Mist and water to the brush reservoir
- Turn on the brush and gently mist while brushing through the coat
- Remove collected hair as needed — no rinsing required
Detailed instructions with exact amounts are included on the packaging.
No. FreshFur is designed for everyday cleanups between baths. It helps keep your pet fresh without the hassle of frequent bathing.
We’ve heard countless reviews from customers saying their pets actually relax — and in many cases even fall asleep — while being brushed with FreshFur. Many pet owners tell us their pets were nervous around other brushes in the past, but the gentle misting combined with slow brushing helps create a calmer experience. As with anything new, we recommend starting slowly and letting your pet get comfortable over a few sessions.
