5.1 Familiarizing Your Pet
It is crucial to acclimate your pet to the grinder to ensure a stress-free experience.
- Allow your pet to sniff and investigate the grinder while it is off.
- Turn on the grinder (without touching their paw) so they can get used to the sound and vibration. Offer treats and praise.

- Once your pet is comfortable, proceed to nail grinding.

5.3 Grinding Your Pet's Nails
- Turn on the LED lights by pressing the dedicated light button. The dual LED lights illuminate the nail, making the quick visible and preventing over-grinding.
- Choose the appropriate port on the protective cap based on your pet's nail size. For very large nails or faster grinding, the cap can be removed.
- Gently hold your pet's paw and carefully place the nail into the chosen port.
- Grind each nail for no more than 5 seconds at a time. This prevents the nail from overheating and causing discomfort.
- Repeat the process as needed, checking the nail frequently to avoid grinding too far.
- Always reward your pet with treats and praise after each successful grinding session.
