Dog Nail Anatomy

Dog Nail Anatomy
Dog nail anatomy is different than a human’s nails.

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.

Trimming Your Dog’s Nails

Dog getting Nails Trimmed
Trimming nails with clippers can be intimidating, which is why we recommend a grinder instead.

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, carpets, or other household items, trimming its nails could also reduce home damage. You also reduce the chance of getting scratched and breaking the 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.

Dremel Grinder Overview

Dog Getting Nails Grinded
Nail Grinders, (AKA Dremels) are easier to use than standard clippers.

The most modern Dremel grinders for dog nails allow owners to trim their pup’s nails without the fear of cutting through the quick. 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.

It takes more time to grind down the dog nail as opposed to the quick snip from a set of trimmers. Owners may like the longer time to ensure they round out and smooth the dog nail before getting to 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. You’ll also need to keep hair away from their paws, and using a deshedder is preferable for that job.

Buying Guide & Considerations

There are 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 downright 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.

Best Nail Grinders For Dogs

Finding the right nail grinder can be a challenge for multiple 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.

Dremel Pet Grooming Tool

7300 Dog Nail Grinder
  • Extremely lightweight.
  • Open Dremel head for flexibility.
  • Budget-friendly.
  • Dual speeds.
  • Low noise frequency.
  • 60 grit sand drum.
  • Sanding drum can be replaced.

Behold, the grinder that started it all. Dremel was one of the first companies to make electric nail grinding, leaving clippers in the dust. They’ve had more time to improve their product and make it the best possible for dogs and dog owners.

This grooming tool consists of a battery-powered motor and a 60-grit sanding drum to file down your dog’s nails. It comes with two rotation speeds (fast and slow, basically), so you can quickly file down the length of your dog’s nails before smoothing it out with the slower speed.

The cordless operation allows you to trim your dog’s nails in the garage, out in the backyard, or in the bathtub. With plenty of space to monitor how close you’re getting to the quick, you can safely and humanely trim your dog’s toenails with a reduced chance of cutting the quick.

It’s a bit more expensive than other dog nail grinders, but this Dremel-style dog nail trimming tool is one of the best on the market. It’s quick, easy, and safe to use, and the durable construction allows you to use the tool for multiple dogs and for many years to come.

We love that this dremel quickly, safely, and efficiently can file down a dog’s nails.  It’s rechargeable and has a removable battery for maximum portability.  It can be used for thick and thin dog nails.  It’s also safe to use on cats.  It’s great for dogs that are scared for clippers, and you’ll rarely grind low enough to cut the nail quick.

The grinder wheel included in the package is supposedly strong enough to cut diamond, so you’ll rarely need a replacement. But just for extra measure, INVENHO includes an extra grinder wheel upon purchase should you lose or break your original one.

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.

We love that this grinder has a quiet motor to make noise-averse dogs feel at ease.  It includes a USB charging cable and has multiple filing speeds, making it easy to turn down if your pup starts to get spooked.

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 are some good reasons why it’s a good fit for most dogs.  Let’s look at some of the FAQs.

Is Nail Grinding Painful for My Dog?

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, make avoiding the quick a lot easier.

Always make sure there are 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.

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

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.

Do You Need Attachments For a Dremel Dog Nail Trimmer?

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.

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. 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. This obviously depends on how many dogs you have. It’s worth the investment for your dog’s 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. This helps ensure dog owners can safely and effectively trim their pet’s nails. All the tools on this list are high-quality, affordable, and will get the job done. We recommend the 7300 Dremel model dog 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. It’s one of the cheapest, has a USB rechargeable battery, and comes in two speeds. The capless grinding system makes trimming small, medium, and large dog nails a breeze. Casfuy is also an excellent pick and has brand recognition behind it. Either pick is sure to provide your pup with a nice, easy grooming experience.
