Dog Nail Anatomy

Dog nails compare to human nails. If you look at your fingernail right now, you’ll see the white nail and the meaty pink part underneath. The nail itself is called the nail plate, and the pink part is called the nail bed.

If you’ve ever trimmed your nails in a rush, you’ll know it hurts to cut the nail plate too close to the nail bed, as the latter holds sensitive nerve endings. The white part doesn’t contain any nerve endings, but the fleshy underside holds the blood supply to nourish the nails.

The same is true for dogs and their nails. The white part of the dog claw is their non-nerved nail, with the sensitive area with blood vessels called the quick.

Your dog will yelp or squirm if you hit the quick. Cutting the quick could even draw blood, which could cause your dog to fear nail trimming in the future.

Therefore, if your dog has white nails, ensure you’re in a well-lit area or hold the dog’s paw up to a light to see the quick. If your dog has dark nails, you’ll have to find the quick through trial and error.

Should I Trim My Dog’s Nails?

You don’t have to trim your dog’s nails just like you don’t have to trim your nails. But for general comfort, health, and safety, it would be best to cut your dog’s nails.

Imagine you haven’t cut your toenails for so long that they curled beneath your toes. It would hurt to walk because the nail would press against the sensitive nail bed with every step.

Not only that, but your toes would get snagged on random carpet threads, small roots, sidewalk cracks and myriad other inconveniences in the world, which could mean random trips or potential damage to your foot, toes, or ankles.

Another reason is aesthetics. Some owners prefer the look of trimmed dog nails. If your dog scratches against doors, carpet, or other household items, trimming its nails could also reduce home damage. You also reduce the chance of getting scratched and breaking skin.

In the wild, a dog naturally files down their nails from walking so much, but they often don’t have the same luxury as a domestic dog. Pet dogs are much more sedentary, so their nails grow longer until they curve near the paw pad.

If your dog stays exclusively outdoors or you exercise it frequently, you might not have to trim its nails. But if your dog lives a relaxed life, it would be best for you and your dog to trim its nails from time to time.

There are numerous options many pet owners and professional groomers use to trim a dog’s nails, but grinding is the best option in terms of tool longevity, results, and efficiency for owners.

Dremel Grinder Overview

The most modern Dremel grinders for dog nails allow owners to trim their pups nails without fear of cutting through the quick. Despite being the most expensive option, Dremel grinders improve nail trimming safety for the dog and help owners cut their dog’s nails.

Essentially, a Dremel for dog nails is like a concentrated bit of sandpaper to file down the dog’s nail instead of cutting it off completely. The owner pressed the grinder onto their dog’s nail, creating a smooth nail edge as opposed to a sharp-edged one. Owners can also stop filing before they reach the quick.

It takes more time to grind down the dog nail as opposed to the quick snip from the previous two trimmers. Owners may like the longer time to ensure they round out and smooth the dog nail before getting the quick, others may dislike the longer time spent. It comes down to preference if you or your dog enjoy the Dremel.

Pros: Using a dremel grinder creates smooth and rounded nails.  It’s easy to control where you stop before reaching the quick of the nail.  It works on any dog nail, thin or thick, whereas clippers don’t work as well on thick nails.  It can also be used perpetually.

Cons: Buying a dremel isn’t as cheap as just picking up a set of standard trimmers.  It’s still affordable, just not “cheap.”  It requires electricity to use, and can get warmer during prolonged use, which is worth monitoring if your pup shows signs of discomfort.

Why Grinders Are A Great Choice

Dremel trimmers are motorized nail trimmers, so the noise produced during use may spook your dog. The best way to acclimate your dog to this trimmer is to keep in on near your dog without trimming its nails.

More advanced models provide a quiet experience and could soothe the anxiety of dogs who don’t like loud, mechanical noises. Since nail dust rises around the grinding site, some Dremels capture the particles in a sort of box which you can dump in the trash once the nail trimming session is done.

It’s recommended to trim your dog’s nails with a Dremel grinder outside, since the dust may cause breathing issues or smell unpleasant in closed areas. But it’s another reason to get your dog playing outside.

Many dog groomers will still use older tools for personal preferences or out of habit, and each come with their perks, but dog nail grinders are the most efficient tool to use.  Keep in mind, you’ll want to ensure you keep your dog groomed to make accessing their nails easier.  If they have long hair or a double coat, make sure to use a deshedding tool to keep fur away from their paws.


Factors To Consider

There’s a few things you should consider before buying a nail grinder to work on your pup. Making a mistake when looking at any of the following factors can end up where you’ve bought something you don’t use, or that your pup won’t let you use because they are down right scared when you try to trim their nails.  That’s why it’s important to make sure you consider all aspects of picking out the right dremel for your dog.

Noise Levels

The most important factor to look at before cost, is noise level.  This is the single biggest reason that a nail grinder may not work for your pup.  If your dog spooks easily, it can be really tough to get them to sit still through an entire grinding session.  So noise is something you should make a top priority.

Adjustable Speeds

No need to grind your pup’s nail at the speed of light!  It’s also true that most grinders that have an adjustable speed setting, will also drop in noise as the speed gets reduced.  Having an adjustable speed level can make a difference both in noise, and in the level of comfort your dog experiences during the grind.

Dremel Bit Material

Most rotary tools will have a bit that’s covered in a sanding drum material.  This will gently tear down the nail as you grind it, instead of outright clipping your pup’s nail which is far more likely to cause injuries to the dog’s quick if you are inexperienced with nail trimming.

Battery Life

Does your grinder need to be plugged in constantly?  That’s something to think about, especially if you like to travel with your dogs.  If you spend lots of time away from home, it’s important to take battery life into consideration so you don’t end up unable to clip your dog’s nails while away from home.


Top Dog Nail Grinders

Finding the right nail grinder can be a challenge for mulitple reasons.  Most notably, is the fact that it may frighten your dog if you use one, so finding the right nail grinder for your dog is extremely important.  Using a dremel isn’t the choice for every pup, and if you have an anxious dog, they may be better of with traditional nail trimmers.

With that being said, there are a few grinders out there that are heads and paws above the rest.  Let’s take a look at our favorite grinders, and break down the reasons why we like each of them.

This INVENHO dog nail grinder includes an attachment to go on top of the grinder wheel, making it easier to cut a small dog’s nails with the small opening (like a window to the side of the grinder wheel), the flat top of the grinder wheel for medium dogs, and completely off if the dog is over 50 pounds.

If you have multiple dogs of different sizes, you can use the same nail grinder for all of them. With the high-quality build and long-lasting battery, the INVENHO pet nail grinder could last your pets for years to come.

Frequently Asked Questions

Here are some of the most frequently asked questions when it comes to grinding your dog’s nails.  Again, this process isn’t something that every dog owner will want to participate in, but there’s some good reasons why it’s a good fit for most dogs.  Let’s look at some of the FAQ’s.

Q: Is Nail Grinding Painful for My Dog?

A: No — unless you grind into the quick, which is the blood vessel in a dog’s nails. As with human nails, the cuttable part of the nail consists of dead cells. It doesn’t hurt to cut your nails unless you get too close to the nail bed, where the nerve endings are.

The same applies to your dog. You have to avoid the quick while still ensuring your dog’s nails are as trim as possible. Certain tools, such as the best Dremel dog nail grinders, makes avoiding the quick a lot easier.

Always make sure there’s no growths or any type of injury to your dog before grinding, like an embedded foxtail into the paw.  This will make nail grinding painful, and you won’t get far.  It’s important to understand the basics of canine behavior so you can understand if any part of the experience causes them pain.

Q: How Long Should I Wait Before Grinding My Dog’s Nails?

A: The time it takes for a dog to grow their nails depends on the breed and nutrition. A good rule of thumb, though, is that if your dog’s nails reach the floor, it’s time for a trim. And if your dog’s nails are particularly pointy and sharp, cutting skin or clothes, trim its nails more frequently.

Q: Do You Need Attachments For a Dremel Dog Nail Trimmer?

A: Yes. When you buy the best Dremel for dog nails, you’ll get a few attachments in the packaging. Through time, though, the rough sandpaper texture used to file down the dog nail will lose its efficiency over time.

Q: What Should I Do If I Accidentally Grind into the Quick?

A: While the best dog nail grinders reduce the possibility of cutting into a dog’s quick, the possibility is still there. Have these precautions ready and treat the wound as quickly as you can.

Styptic Powder or Styptic Pencil: 

Even professional groomers make mistakes and clip a dog’s quick, but they use this powder to quell the bleeding and disinfect the area. Some styptic powders even contain an anesthetic to reduce pain. Just apply a little powder to the wound and pressure to stop the bleeding, and you can go back to trimming your dog’s nails.

One tub or pencil of styptic powder can last up to five years depending on how many dogs you have, so it’s worth the investment for your dogs comfort during Dremel nail trimming.

Corn Starch: 

If you don’t have styptic powder or its pencil on hand, corn starch works well too. Sprinkle some corn starch onto the dog’s wound and wait for the blood to clot. Once the bleeding stops, wash off the wound to prevent your dog from licking at the bloody corn starch on its foot.

Corn starch won’t disinfect or numb pain, but it will stop bleeding quickly and cheaply. And you probably have some in your kitchen right now.

Final Thoughts

There are lots of great dog nail grinders on the market, ensuring dog owners can safely and effectively trim their pet’s nails. While all the tools on this list are high-quality, affordable, and will get the job done, we recommend the INVENHO pet nail grinder as the best dog nail grinder and Dremel-style nail filer.

The reason is simple: it does what the other dog nail grinders do but better. It’s the quietest nail grinder on this list, coming in at 40 decibels. It’s one of the cheapest, has a USB rechargeable battery and comes in two speeds. The three-port filing system makes trimming small, medium, and large dog nails a breeze.

So what’s not to love? When the competitors offer comparable services, INVENHO does it all a little better. That’s why I picked it as the winner.
