Questions & Answers

13 Customer Questions

How do I know when I've trimmed enough? Is there any risk of grinding into the quick? My dog has black nails and a very long quick, according to the vet tech who trims her nails (and makes at least one nail bleed almost every time).
Answer by ChewyJun 29, 2017
The pet's nail must not be able to scratch or touch the floor. However, it will also depend on how comfortable the dog will feel while going through this process.

Is it quiet?
Answer by ChewyJul 14, 2019
This nail grinder is specially designed with a super mute motor for low noise and vibration

Do you have to plug this in to a computer to charge it? The picture does not show a way to plug it into a wall outlet.
Answer by ChewyAug 01, 2017
This clipper comes with a USB charger. Plug the charger into a USB port in your computer or a USB adapter to plug into a wall outlet.

How many uses can I get? If no replacements are sold?
Answer by ChewyNov 21, 2018
The longevity of the diamond bit depends on how often it's used.

Doesn’t Last

It worked okay the first two times I used it. Then the file became smooth so it won’t file and the battery only lasts through maybe one paw. It’s great that there’s no cords but it just doesn’t work. Maybe a small dog with thin nails would work but for my beast with thick nails it was a waste

Dog approved

Glad I bought this nail grinder. Nail clipping is always a chore. My mini schnauzer fights me the whole time and tucks his paws under him. I used other grinders in the past with no luck. This one works great and he allows me to do his nails with out any issues.

battery will no longer holds a charge - have to use it while plugged in

Used several times works great, love this design, relatively quiet. Great with my small dogs they get treats and by now they seem to enjoy the paw massage. Much more easy to handle and quieter than the heavy-duty "shop tool" nail grinders . Easy to monitor progress and avoid reaching the quick. PROBLEM is that after about 6 cycles, the battery will no longer hold a charge. There are many companies with the same design - find one with better electronics - like a charging indicator that works.

Hertzko nail grinder

I love this grinder no cords blocking your way and the sound is so much smoother, less noise and Bella is not so up in arms about it. Nails come off so much smoother and nicer than the previous grinder I bought. Thank u

My 7 lb chihuahua has 5 dew claws, 2 of which wrap around his little paw pads. As such, he needs constant nail trims and the groomers miss the dew claws 50% of the time. It is very stressful for all involved and I have been searching for a long term solution. My pup let me use this to grind down his dew claws with zero fuss. I am still in shock. It worked well, is fairly quiet, has good guards and now I have my long term solution I have been searching for.

Glorified nail file

This only lasted one time. My dogs nails were in need of a trim but the grinder is already weak and no longer filing

Not for large canines

Definitely not for large canines, I have two German Shepard’s and this wasn’t working at all. Seems a bit flimsy and cheaply produced. It’s useless

Bummer purchase

I would not recommend this for a large dog. I have used mine only a handful of times and it’s not cutting well unless I press hard and the dog does not like that. Plus you can not replace the head which is ridiculously wasteful. The only positive is, it is quiet as advertised.
