Trimming Dog Nails with a Dog Nail Clipper

This is the tool that I started with some 20+ years ago.  Tried and true. The traditional dog nail clipper is a tool that gets the job done.

Guillotine Style Nail Clipper

There are two types of dog nail clippers.  A guillotine nail clipper and a scissor-style nail clipper.

With a guillotine clipper, a single blade comes down and slices off the end of your dog’s nail (like a guillotine).  

While simple, I do not recommend this style for people with large or giant breed dogs as it is not quick or powerful enough to cut the thicker, stronger nails of our big dogs.

The scissor-style traditional nail clipper is the style I have and recommend for large dog owners.

This style consists of two blades that come together to cut your dog’s nail (like a scissor). The amount of force you are able to generate with this style of nail clipper is better for the thicker nails of large and giant breed dogs.

There are some variations of dog nail clippers with a sensor or led light that claims to help with identifying the quick before you hit it, however, I do not recommend these. 

Not only am I not convinced that they even work, I know that identifying the dog nail quick is NOT the source of the problem even if these tools worked as they claim. 

So if you found this post and are looking for the best dog nail clippers with a sensor, I urge you to keep reading and consider an alternative.

Here are the pros and cons of a traditional nail clipper for dog nails:


  • Conditioning to a dog nail clipper is less complex. While there are a sound and sensation associated with using a clipper, it tends to not elicit the same reaction from dogs initially and may be less intimidating for some dogs and owners.
  • Dog nail clippers are significantly less expensive to purchase, running between $6.00 – $15.00 on average.
  • Durable and long-lasting.  The nail clippers I purchased over 20 years ago are the ones I still use today.  With regular sharpening, the blades are easy to maintain and last forever.
  • The simplicity of use makes the dog nail clipper an obvious choice for new dog owners and beginner home groomers.


  • Large and giant breed dogs have thick nails (and often black nails) which can be hard to cut with a traditional dog nail clipper.
  • The “Clip and Pray Method” is often used with a nail clipper. This is when dog owners take one giant clip of nail off while saying a silent prayer that they didn’t hit the quick. See below for tips on how to avoid hitting the quick with a clipper.
  • Traditional dog nail clippers take a decent amount of hand strength to use making them a poor choice for people with arthritis or reduced hand strength.
  • Nail clippers require regular sharpening in order to make clean cuts on the nail.
  • Technique matters when using a nail clipper, so learning to clip properly is key.
  • Bleeding is usually worse and more frequent when using a dog nail clipper due to the low accuracy of the clipper when cutting.

Tips For Using a Clipper on Black Dog Nails

Nail Clipper or Dremel for Dog Nails Tool Guide Pin 1

Remember that black nails are just the color on the outside. The anatomy of the inside of the nail is identical. The only difference is that you can’t see the quick as easily.

That said, there are a few things to consider when it comes to using a nail clipper on black nails.

  1. Prioritize proper conditioning before attempting to clip your dog’s nails.
  2. You can often view your dog’s quick (or approximate location) from the underside of the nail.
  3. Maintain your clippers with proper sharpening. This will ensure you are getting clean cuts off of the nail and not causing your dog discomfort.
  4. The only way to shorten a dog’s nail is to put pressure on the quick to force it to recede. You do this by clipping right up to the quick with each nail session.

How To Use a Clipper And Avoid Hitting the Quick

I mentioned above, the dreaded “Clip and Pray Method” for trimming dog nails. This is the method used by the vast majority of dog owners who rely on a nail clipper. They pray with every clip that they haven’t hit the quick.

This is method is particularly common with dog owners of dog’s with black nails since they can’t visually see the quick in order to avoid it.

Consequently, dog owners become anxious about nail trimming due to a higher incidence of bleeding. This results in owners fearing the quick so much they fail to cut enough off the nail.

  1. Condition your dog to love nail trims so he or she is still, patient, and not doing the paw-pulling dance (not sure how? Click here).
  2. Start by identifying approximately where your dog’s quick is (see image to the right) on the underside of the nail. This step is not necessary, but it can help give you an idea of how much nail you can take off.
  3. Gently hold your dog’s paw and steady the toe between two fingers.
  4. Holding a scissors-style nail clipper at a right angle (sideways) to the nail and begin clipping the tip off of the nail to shorten it most of the way to the quick.
  5. Continue making tiny cuts around the nail – 5-10 or so – in order to further shorten the nail and remove any sharp edges.
  6. Clip until you start to expose the soft part of the nail revealing a little dark spot which is the quick. STOP HERE! ❌

Best Dremel for Dog Nails

Invented in 1934, the Dremel is a high-speed rotary tool used for an endless number of projects from jewelry making to drilling holes to cutting dog nails.  Most Dremels come with a wide range of highly engineered accessories, including several sandpaper bands of varying grits.

According to

“The Dremel brand is dedicated to empowering Makers through creativity, precision and project enjoyment.”

This should read “Makers AND Dog Owners” as there is nothing more enjoyable than Project Dog Nails, am I right?

The following are the pros and cons of using a Dremel for dog nails.

  • Precision and accuracy are unmatched by any other tool used for trimming dog nails. A Dremel allows you to sand right up to the quick without hitting it.
  • The flexibility of options for speed and level of grit needed.
  • Efficient nail trimming. With a classically trained dog, nails can be done in a few, stress-free minutes, but may take slightly longer than with a dog nail clipper.
  • A Dremel produces smooth, rounded nails that don’t hurt or catch on fabric, carpet, or furniture.
  • Ease of use.  A Dremel takes little to no hand strength so it is a great option for women, people with small hands, or those with reduced hand strength.
  • Fewer bleeding issues due to improved accuracy, precision, and slower grinding.
  • When using the Diamagroove Dremel Bit, a diamond rotary bit, you can trim your dog’s nails with less heat and greater precision than with a standard sandpaper bit. I have been using my Diamagroove Boxer for over 5 years and it still looks like new! If you are curious about this unique Dremel bit, click here for a more in-depth review of the Diamagroove.


  • Learning how to Dremel dog nails properly can take a little longer as conditioning to the sound and vibration of the Dremel is key to long-term success.
  • Sound can be scary to some dogs initially.
  • Dremels are the most expensive nail trimming tools.  A cordless Dremel Micro 8050 runs about $65 on Amazon and most of the electric versions can be $100 or more including the cost of the kit.
  • Electric (Corded) Dremels, like the Dremel 4000, can get heavy, especially for people with smaller hands. I use a flex attachment which is an extension that can be added to a corded Dremel.  This makes nail trims super easy with little to no effort at all.
  • The battery life of the cordless Dremel is about 2-4 years on average depending on usage. Replacement batteries are available for purchase.

Should You Buy a Pet Dremel?

It seems like every day there are new versions of pet Dremels. With features that promise to warn you of the approaching quick, grind faster, and with less noise, these pet Dremels sound great.

But are they any better for dogs, especially big dogs, than the tried and true Dremel?

In the spirit of full transparency, I have never purchased one of these pet Dremels. I would love to try the PawControl by Dremel to test out the claims, however, here are my general thoughts as it relates to pet Dremels.

1. Cost

Most of them are not that much less expensive than the basic Dremel Micro. Most of the pet Dremels I’ve seen are between $20 – $50, with the Dremel Micro 8050 today on Amazon sitting at $68.

2. Power

The jury is still out for me on how well the pet Dremels like the Dremel 7020Dremel 7760 PawControl, PawPerfect, Peteast Dog Nail Grinder, or FURminator Nail Grinder will hold up to the demands of large and giant breed dogs getting frequent trims.

However, according to big dog owners that have taken Dog Nailpro™ and who are in the Big Dog Mom Community, pet Dremels do not offer enough power for very large dog nails.

I would love to know how this compares with your experience, so comment below and let me know.

3. Marketing Claims

Do your due diligence as you shop for a pet Dremel. Many of these new tools make claims, especially about the quick, that may not work as expected.

Be sure to read all of the reviews before you buy.

Caveat emptor!

Tips For Grinding Black Dog Nails With a Dremel

In my many decades of using a Dremel for dog nails, I have found one thing to be true. As long as your focus is on proper conditioning so that your dog learns to love nail trims, whether your dog has black nails or light-colored nails is inconsequential.

That said, there are a few things to consider when it comes to using a Dremel on black nails.

  1. The quick is in the same place regardless of the outside color of the nail. So HOW you trim the nail to avoid the quick (see below) will be the same for both.
  2. Black nails on large and giant breed dogs tend to be much thicker and stronger on average, so trimming them will take slightly more muscle regardless of the tool you choose.
  3. While this is anecdotal, I have found black nails grow faster than light nails. This could just be on my own dogs, how they wear down their nails naturally, or due to me not trimming enough off during each session, however, I have noticed that this is true for my dogs. How quickly they grow helps me determine how often I need to trim them.

How to Avoid Hitting the Quick With a Dremel

Avoiding the quick using a Dremel for dog nails is less complicated than it sounds, even if your large dog has black nails.

Here is how you do it….

  1. Condition your dog to love nail trims so he or she is still, patient, and not doing the paw-pulling dance (not sure how click here).
  2. Set your Dremel on the low – medium speed setting.
  3. Gently hold the nail between two fingers to steady it and reduce the vibration.
  4. Grind starting in the center with a little pressure to shorten the nail (how much pressure and duration of time will depend on your dog and his or her nails).
  5. Move outward to finish the nail, continuing to slowly grind in the middle.
  6. Eventually, you will see a small black center which is the quick. STOP HERE! ❌
  7. You can continue to polish the nail on the sides and top, but be sure to avoid the center at this time, or you will hit the quick and the nail will bleed.
  8. If you do happen to hit the quick, here is how you can stop the bleeding.

Other Tools for Trimming Dog Nails

While not as popular or commonly used, a comprehensive overview of tools for trimming dog nails would not be complete without information on dog nail files and scratchboards.  Here is a brief overview of these alternative options.

Metal File for Dog Nails

metal file is just what it sounds like.  Most are about 4-6 inches long and would be used like a human Emory board or nail file.  The only difference is that one is metal, the other is usually sandpaper.

If you are looking for a good laugh, do a quick search on Amazon for “file for dog nails.”  I cannot imagine using any of these products on my huge Mastiffs!

While I have not used a file for my dog’s nails personally, here are some pros and cons to consider:


  • Precision in cutting without hitting the quick
  • Files are Inexpensive to buy


Scratchboard for Dog Nails

One of the members of the Big Dog Mom Community Facebook Group shared some videos of her dog using a scratchboard for trimming his nails.  

This product is essentially a board with sandpaper covering it. Dog Training Nation shares here how to DIY your own scratchboard if you are interested in learning more.

  • Provides an alternative to a traditional dog nail clipper and a Dremel for dog owners looking for one.
  • A scratch board would be more efficient and effective at trimming thick big dog nails than a metal file.
  • Homemade DIY scratchboards are easy to make.


  • A scratch board is not a viable option for most dog owners since getting sufficient cut length on all nails is extremely difficult, if not impossible.
  • Requires extensive training to teach the dog how to scratch his nails across the board.
  • No precision or accuracy in shaping the nail.
  • More time-intensive as compared to a traditional dog nail clipper or Dremel.

Miscellaneous Tools for Nail Trimming

In addition to the tool you select, you will want to make sure you have a couple of other items on hand before you begin trimming your dog’s nails.

We referred to dog nails bleeding a few times in the course of this guide, but I did not go into detail about it. Assuming you know how and why a dog nail bleeds (if you would like details on this, read this post all about the quick), for the purposes of this discussion, we are simply addressing the tools you need to stop the bleeding.

While I rarely use it, as I mention in the video, I do keep a container of Kwik Stop or my DIY Styptic Powder on hand just in case I accidentally hit the quick.

The final tool that is absolutely essential for trimming dog nails is TREATS!

Remember what I said in How to Socialize Your Puppy At Home: 15 Creative Tips (That Work)

Dogs understand food and treats. We don’t have to teach them what food means. So the best way to condition your dog to LOVE nail trims is with food!

Now… do NOT start slathering peanut butter all over your forehead. That serves only two purposes – to coerce your dog into tolerating a nail trim and make a giant mess all over you and your floor. This does not teach your dog anything.

Treats are used for a specific purpose, in a specific way, so I have a few criteria that I use for treats that I use in nail trimming. They are:

  • Small in size
  • Soft, not crunchy
  • Mostly dry in my hand
  • Easily accessible
  • Home-cooked and DIY foods are great to mix in as well
  • Nutritious

Here are a few treat options that fit all of these criteria, or you can go to my Amazon store which has a curated list of many more healthy treats for dogs.

Dog Nail Trimming Tool Decision Guide – 7 Factors To Consider

  1. Your level of fear and anxiety over hitting the quick.
  2. Size of your dog. The larger the dog nails, the more comfortable you will be with a Dremel.
  3. Comfort level in training and conditioning your dog to love nail trims.
  4. Your size and hand strength. Petite women with small hands may find the Dremel easier to handle for very large dogs.
  5. Cost as a factor. There is a moderate price difference between a nail clipper and a Dremel. You may save a little money by choosing a pet Dremel, however, for giant breed dogs, pet Dremels may not be the best choice (see above).
  6. How many dogs you will be trimming. Given the hand strength required with a nail clipper, those with multiple dogs may appreciate the ease of using a Dremel over. an extended period of time.
  7. How much experience you have trimming nails. If you are a first-time puppy owner or are starting to trim nails for the first time, a nail clipper is an easy tool to start with.

  1. I love my Dremel Paw control nail grinder- recommendation of our breeder. When Moose was little I would turn it on and lay it beside him then just rub his nails and toes, then slowly moved into trimming. I trim as much as I can and if it still needs trimming I wait three days and grind some more.
    I’m way too scared to use clippers.
