What to consider when searching for the best dog nail grinders

Why is it important to cut my dog’s nails?

A domesticated dog needs assistance when it comes to taking care of health and hygiene. Just like we need to bathe, cut our hair, and trim our nails to keep up not just our appearance but maintain our overall well-being, dogs rely on the same routine for the exact same reasons. While frequent walks on pavement or concrete can help naturally file down a dog’s nail, dedicated filing or clipping is critical. If your dog’s nails get too long, that can start to affect their gait and stress their joints. Beyond that, if their nails continue to grow, they can puncture their footpads or injure themselves when scratching. While the best thing you can do is regularly take your dog to a professional groomer, an at-home nail grinder means you can keep them in tip-top shape, even if the pet spa is all booked up. 

How do I even use a nail grinder?

A nail grinder uses a high-speed rotating head with a textured bit, much like sandpaper, to gently file down canine nails. While they take longer to complete the task than trimmers, a doggie nail file can be a safer alternative, especially for sensitive dogs. All you need to do is hold the grinder up to your dog’s nails and gently move the tool back and forth. Your nail grinder should be light, easy to grip, and either come with a power cord or long-lasting batteries that are rechargeable or replaceable, so you don’t need to stop mid-trim. It’s a good idea to acclimate your pup to the sound of the grinder before taking it to their nails, and it’s never a bad idea to prepare treats for them post-pedicure.

A grinder results in smooth nail ends, eliminates cracking, and gives ample time to assess how close you are to the quick. The quick is the pink part of the nail that delivers blood. While you want to ensure you don’t grind this area down, regular nail trimming will naturally cause it to recede, which is beneficial! If you’re feeling particularly nervous about over-trimming, look for a grinder that comes with a guard, which will put a physical barrier between you and a sensitive part of the nail.

What size dog do you have?

Generally, the size of your dog will tell you about their nail thickness. Small dogs typically have thinner nails that don’t need a super coarse grinding bit or multiple speeds. Larger dogs have thicker nails that need a little more power behind the grind. Multiple grinding speeds can help whittle down tough areas, and a diamond or stainless-steel sanding drum will increase efficiency. A really powerful grinder has the potential to heat nails to an uncomfortable degree, so it’s a good idea to work in quick bursts and pay attention to any intense heat coming off of their nails. Age and breed can also impact your dog’s nail density. Before purchasing, we recommend palming your dog’s paws and scoping out the tool’s specs to double-check the grinding gear can handle the trim.

Does your dog have dark fur and/or dark nails?

Trimming your dog’s nails on your own can be anxiety-provoking, especially if you have difficulty distinguishing the nail from the fur. If Fido is rocking a dark nail-dark fur combination, consider investing in a nail grinder equipped with an automatic LED light. This guiding light will illuminate everything you need to see to protect your puppy from any inaccuracies.

Q: How much does a dog nail grinder cost?

The dog nail grinders on this list start at around $23, with our final topping out at over $35. The combo kit tops the list but comes with a nail grinder, clippers, and nail file.

Q: What happens if you never cut your dog’s nails?

Just like human nails, dog nails will continue to grow until they are filed or cut down. Dog’s nails can receive free filing from frequent walks on rough surfaces, like sidewalks or rocky terrain, but that’s typically not enough. You’ll want to trim your puppy’s nails regularly to prevent them from growing too long and getting in the way of their walk, or worse, scraping and puncturing their foot pads. 

Q: How often should you grind your dog’s nails?

On average, you should be cutting dog nails every one or two months, depending on how fast they grow. If they go on frequent walks across concrete, this time might be extended. Generally, when you can clearly hear your dog’s nails scratching against the floor when they run up to greet you, they could probably use a trim. 

Q: Does grinding a dog’s nails hurt them?

No, grinding a dog’s nails should never hurt them. Just ensure you have proper control over the grinder and a good handle on your canine’s paw. Trimming and grinding do not hurt or irritate your dog, but the vibration and noise of the machine can scare some dogs. If possible, start grinding down their nails when they are a puppy, or, if you’re well past that stage, let them get used to the noise before starting on their paws. 

Final thoughts on the best dog nail grinders

Just like us, dogs need a certain amount of upkeep to ensure they are looking and feeling their best. The best dog nail grinder will make it easy to take care of your pup from the comfort of your home. A particularly useful tool for older dogs, you can ensure their happiness and safety in between trips to the groomer. Just make sure you grab a grinder suitable for your dog’s size and temperament before setting up a spa day and pampering your pooch. We’re sure your furry friend will thank you later in the form of slobbery kisses and tail wags.
