The 8 Best dog nail grinder for black nails

Nail clippers are great tools to trim your dogs’ nails. They are also useful for humans, especially those who suffer from ingrown toenails or other foot problems. But they aren’t always effective at removing the thickest layers of dead skin around the cuticles.

A nail grinder is a tool that removes the outer layer of dead skin cells. This helps prevent ingrown toenails and other foot problems. Nail grinders come in various sizes and shapes, but they all share similar features.

What you need to know about grinding your dog’s nails

It can be stressful to trim your dog’s nails if you have never done it before, but you don’t have to be! If you follow these steps, it is fairly easy to trim your dog’s nails using a nail grinder:

  1. Getting your dog used to the nail grinder: Your dog is likely to be unsure at first about the nail grinder. For a few days, turn the nail grinder on and off near your dog to get your dog used to it. You can praise and reward your dog whenever they don’t react negatively to the nail grinder. You can easily incorporate this into your routine by turning on the grinder when your dog has a meal in order to establish a positive association.
  2. Ensure paw hair is short: Next, check the length of the hair on their paws. To prevent your dog’s hair from getting caught in the grinder, you should trim the hair between his paw pads before using it.
  3. During the entire nail grinding process, your dog should remain in a comfortable and secure position. Consider enlisting the assistance of a friend or significant other if your dog is large or a squirmer. You may want to hold your dog using your nondominant hand. When grooming your nails, you will be able to hold the nail grinder firmly in your dominant hand.
  4. As a warm-up, turn on the nail grinder while holding your dog and allow it to run for a few seconds. As a result, your dog will not be startled by the noise.
  5. To grind a nail carefully, start by grinding one nail with the dremel. This can be done by applying the grinder directly to the bottom of the nail tip and moving it slowly upwards and over the nail.
  6. Grinding down one layer at a time: Work your way down the nail length, rounding off any sharp edges with the nail grinder.
  7. Make sure you don’t grind the nail too deep: Be sure not to grind the nail too deep. Check each nail during the process to avoid touching the nerves at the center of the nail.
  8. To polish your nail, grind the tip of the nail in a circular motion in order to finish off your nail grinding session.
  9. This process should be repeated on each nail. At the end of the session, give them a big treat so that they will continue to associate you with grinding their nails.

How often should I trim my dog’s nails?

Each dog is different. Dogs wear their nails down differently, too, and all of their nails grow at different rates. If a heavy, large dog runs around outside on a regular basis, their nails may wear down naturally, requiring less frequent trimming.

It may be necessary to trim the nails of a Yorkie every two weeks if it barely touches the ground. It might never be necessary for a dog who is training for an Iditarod or running a marathon. If you want your dog’s nails to click on the floor, trim them before they grow too long.

When should I start trimming my puppy’s nails?

Start trimming your puppy’s nails when he starts walking on his own. Around 8 to 12 weeks of age, this usually happens.

If your puppy is older, ask your vet about starting nail trimming earlier. Some vets recommend beginning as early as 4 months old. However, this depends on the breed of the puppy. Ask your vet what is best for your particular pup. (3)

Is it safe for dogs to use nail grinders?

When used appropriately, nail grinders are perfectly safe for your dog. Because you can see the layers falling off using a nail grinder, it’s simpler to avoid going too near to the nerves underlying the nail.

When using a nail clipper, all you have to do is snip and hope you don’t cut too deep. That’s why the best way to cut a dog’s nails is to use a grinder, preferably one with a built-in safety feature.

What angle should your dog’s nail be ground?

You’ll have a better sense of the angle and length you should be grinding down your dog’s nails after you start cutting them on a more regular basis. You should clip the nail at a 45-degree angle, according to the groomers at PetCo.

You should never grind their nails too quickly since you need to look for the quick (a blood vessel inside their nail) to see whether it’s been clipped down sufficiently.

What is the purpose of a nail grinder?

A nail grinder consists of a revolving element that functions similarly to a nail file. When this file is turned on, it spins and guides itself around the nail, neatly removing layers of the nail.

Is it preferable to file or grind your nails?

Using a sandpaper-like covering, a nail grinder eliminates the nail layer by layer. Nail clippers, on the other hand, chop the nail off in pieces. A nail grinder is not only safer than nail clippers but also prevents splinters from forming in the nail. As a result, the finished product is significantly smoother. (4)

What is the difference between an at-home grinder and a professional groomer?

Taking your dog to the doctor or groomer on a regular basis for a professional nail trim may rapidly add up. Nail grinders have become a popular alternative for many dog owners because of this. You can receive the same high-quality nail trim in the comfort of your own home (which your dog will love!) and without spending a lot of money if you have your own nail grinder.

How frequently can a dog’s nails be ground?

Your dog’s nails should be cut every four to six weeks on a regular basis. Allowing your dog’s nails to grow too long might cause health issues and nerve damage. The frequency will vary depending on your dog’s breed and activity.

If you walk your dog outdoors on asphalt or concrete, their nails may naturally wear down faster than if they play in a grassy backyard. The length of time you need to clip your dog’s nails is determined by their natural wear.

Can a nail file be used instead of a nail grinder?

The most efficient technique to cut a nail is to use a nail grinder. A file may be used for minor touch-ups, but not for the complete trim. If you wish to use a nail file instead of a nail grinder, trim the nails first and then use the file to smooth off any rough edges.

When it comes to your dog’s nails, how long should they be?

When your dog’s paws are flat on the floor, their nails should be slightly higher than the paw pad, with a gap between the nail and the floor. You’ll need to keep an eye on how rapidly their nails develop to maintain this length.

Each dog’s nails will develop at their unique rate, much like people. This may differ from one breed to the next, and even from one dog to the next.

Is it uncomfortable for dogs to grind their nails?

Trimming your dog’s nails should not be uncomfortable for them, just as cutting your own nails isn’t painful for you. Their nails, on the other hand, have both a blood artery and a nerve, known as the quick.

If you cut your nail too deep, you risk nicking the quick or nerve, which may result in blood and discomfort. The procedure will be painless if you take the necessary precautions.

Are there various grinders for big and little dogs?

You may use the same nail grinder for both small and big dogs when choosing a nail grinder. Grinders with various power levels, on the other hand, could be worth considering. This will enable you to apply a stronger grind on thicker nails and a weaker grind on the nails of your little dog.

What to Look For When Purchasing a Nail Grinder?

Nail grinder models vary in price and features. Here are some things to consider when choosing which one is right for you.

Safety Guard

You need to make sure that the grooming tools you buy are safe and won’t hurt your dog. Buying a nail grinder should be accompanied by a safety guard. When you use a safety guard, you can avoid trimming your dog’s nails too deeply, which can damage his nerves and cause him pain when walking.

Speed Control Switch

A good nail grinder has a built-in control mechanism that lets you set the speed of the tool. A slow setting makes it easier to control the depth of the cut. A fast setting gives you more power to quickly remove the nail.


When choosing a clipper for your pup, you should also consider the size of your pet. Dog nail clippers are sometimes designed specifically for large dogs, so they can be dangerous for smaller dogs. Likewise, a nail trimmer designed for small dogs will not be effective against big dogs’ hard nails. Therefore, you should choose a nail clipper that is appropriate for your pet.

Blade Quality 

A blade’s quality determines how well a cut will finish. A good blade is, therefore, necessary for a smooth and quick clipping process. Its sharpness allows us to get the job done more quickly.

For dog nail clippers, stainless steel should be used as the blade material. Durable and long-lasting, it will save you money over time. Your dog’s nails will also determine the type of blade that should be used.

Settings for power

Each nail will need a different power level to be trimmed – and your dog might prefer a rotational power level. It is a good option to find a grinder that has multiple power settings so you can adjust the speed. If you have multiple dogs of different sizes, multiple power levels are useful. You might need higher power for your large dog with thick nails, while your smaller dog might be better off with the lowest setting.


A sudden, loud noise can startle some dogs. When purchasing a nail grinder, you should consider the noise level if you have a dog with sensitive hearing. Choosing an electric nail grinder with a noise level of fewer than 50 decibels may help you ease your dog into the new experience of grooming. Stress-free experiences are associated with lower noise levels.

Price Point

An expensive nail grinder does not necessarily mean it is of professional quality. In keeping with these principles, all the choices made in this article have been personally vetted by our team. Check out a few models within different price ranges to see which one is the best fit for you by going through the must-have features of your nail grinder.

Is it best to use a nail grinder on my dog?

If you’re looking for a simple solution to keep your dog’s nails trimmed, then a nail grinder is probably the right choice for you.

The device works like a pair of scissors, but instead of cutting hair or fabric, it cuts the nail. There are many types of nail grinders available on the market today, ranging from manual to battery operated.

Manual nail grinders require constant attention, making them difficult to use during travel. Battery-powered devices provide mobility, but their batteries run down after a short period of time.

A manual nail grinder is ideal for trimming your dog’s nails once per week, while a battery-operated model would work well for daily maintenance.

The Benefits of Using a Nail Grinder
Because of its simplicity of use, most people choose to cut their nails using a nail grinder. Other benefits to consider over cutters are:

Some Dogs Prefer a Nail Grinder: If your dog doesn’t like nail clippers, a nail grinder is an excellent alternative. Because they’re not the same, your dog won’t correlate his dislike of clippers with the Dremel.

It’s also a far more efficient and comprehensive choice. This means you won’t have to cut your dog’s nails as often, which is a win-win situation for both of you.

When you use nail clippers to trim your dog’s nails, you’re taking out huge sections of the nail. This often results in jagged or splintered edges, particularly if you have a squirmy dog. An excellent nail grinder can help you produce smooth, rounded nails that won’t catch on furniture, clothes, or carpets.

Ideal for Thicker Nails: Larger dogs have thicker nails, which may make nail clippers difficult to use. In this scenario, nail grinders may be a better alternative.

Nail Grinders Have Drawbacks

Even while grooming specialists prescribe nail grinders, they aren’t always the ideal match. Consider the following drawbacks:

Because a nail grinder is an electric nail file, it makes a vibrating noise while in use, making it louder than clippers. A nail grinder may be too terrifying for your dog if they are easily startled or sensitive to loud sounds.

Power is required: Whether you pick a rechargeable or wired nail grinder, this might be considered a disadvantage. If you’re on the road and need to cut your dog’s nails, make sure your nail grinder is charged or that you have an outlet nearby.

Grinders leave surplus nail filings in the form of dust, while all nail clipping causes waste. Cleaning up might be tough, especially if the grinding is done inside. To prevent eating this dust, you should also invest in eye protection and a face mask.

Excessive filing: It’s still possible to file too much of the nail away and end up hitting the dog’s nail. The nail grinder removes each layer of the nail quickly.

While you may work your way down gradually, determining a stopping point might be challenging. If you grind the nail down too much, the quickness of the nail might be exposed, resulting in blood or discomfort for your dog.
