This article provides general guidance for at-home nail care only. It is not a substitute for professional veterinary or groomer advice. If your dog has severely overgrown nails, nail injuries, infections, or shows signs of pain during trimming, consult a veterinarian or Professional Dog Groomer. If you accidentally cut the quick and bleeding doesn't stop after 15 minutes, seek veterinary attention.
Overgrown nails are one of the most overlooked health issues in otherwise well-cared-for dogs—yet the Kennel Club warns they can cause posture problems, joint strain, and painful injuries if left untreated.[9] The good news? Regular trimming at home is straightforward once you know what you're doing.
Trimming your dog's nails is one of those jobs most owners dread—but it doesn't have to be stressful. The right tool makes all the difference, and knowing when to reach for clippers versus a grinder can turn a dreaded chore into something you actually manage without a meltdown (yours or theirs).
Here's what's at stake: overgrown nails force your dog to shift their weight backward, putting strain on their joints and spine. Left unchecked, this can lead to posture problems, altered gait, and even arthritis over time.[1] (For dogs already experiencing joint issues, see our senior dog joint supplements guide.) Worse still, nails that grow too long can curl under and dig into the paw pad—painful and prone to infection.
The telltale sign that nails need attention? That clicking sound when your dog walks on hard floors. If you can hear their nails tapping on tiles or laminate, it's time for a trim.
This guide breaks down both clippers and grinders—what works, what doesn't, and which option suits your dog best. Whether you're trimming at home for the first time or looking to improve your technique, you'll find practical advice grounded in what actually matters: keeping your dog comfortable and their paws healthy.
Key Takeaways: Dog Nail Clippers vs Grinders
Before you pick up any tool, you need to understand what you're working with. A dog's nail has two main parts: the hard outer shell (keratin, same stuff as human nails) and the quick—the soft inner core containing blood vessels and nerves.
The quick is where things get tricky. Cut into it and you'll cause pain and bleeding. This is the number one reason owners get nervous about trimming at home, and it's completely understandable.
Dogs with pale or white nails have an advantage—you can see the quick as a pinkish area inside the nail. Look at the nail from the side in good lighting and you'll spot where it ends. Stay well clear of that pink zone.
Dark nails are harder. The quick is hidden, so you can't see where it ends. The PDSA recommends trimming only the very tip when dealing with dark nails—better to take off less and trim more frequently than risk catching the quick.[2]
Here's something many owners don't realise: regular trimming actually causes the quick to recede back into the nail. If your dog's nails have grown long and the quick has extended with them, you can gradually encourage it to shrink back through weekly trims.
Dogs Trust recommends trimming a small amount off the end, then waiting a week for the quick to recede before trimming again. Repeat this process over several weeks until the nails reach a healthy length.[3] It takes patience, but it works.
Clippers are what most people picture when they think of trimming dog nails. They're manual tools with sharp blades that cut through the nail in one motion—quick, no batteries required, and they've been the go-to for decades.
There are two main styles, and the right choice depends on your dog's size:
Angle matters. Position the clipper at roughly a 45-degree angle, cutting downward from where the nail starts to curve. This follows the nail's natural shape and reduces pressure on the quick.
Don't try to take off a lot at once. Small, controlled snips are safer than one big cut—you can always trim a bit more, but you can't put it back once it's gone.
Grinders (sometimes called Dremels after the popular brand) use a rotating sanding barrel to file the nail down gradually. They've become increasingly popular among both professional groomers and home users, and there are good reasons why.
Short bursts are essential. Touch the grinder to the nail for 1-2 seconds, then lift off. Never hold it in one spot continuously—this is how burns happen.[5] Professional groomers recommend limiting total grinding time to around 30 seconds per nail.
Work in a "grind-release, grind-release" pattern. File the tip first, then angle to smooth the sides and underneath. This rounds off the nail properly without concentrating heat in one area.
If your dog has long fur around their paws, trim it first or hold it back with your fingers. Getting hair caught in a spinning grinder is distressing and can put your dog off the tool permanently.
The best tool is the one that minimises stress—for you and your dog. Neither option is universally "better"; it depends on your dog's temperament, nail type, and your own confidence level. The Whole Dog Journal notes that while grinders are preferred by most professionals, clippers can do the job perfectly well for most home users.[4]

Many groomers use clippers and grinders together. They clip first to quickly remove length, then follow up with the grinder to smooth edges and get closer to the quick safely. This hybrid method combines the speed of clipping with the precision of grinding.
If you're trimming at home regularly, having both tools gives you flexibility. Start with whichever your dog tolerates better, and introduce the other gradually as a finishing tool.

Even the best tool won't help if your dog panics every time you reach for their paws. Building positive associations takes time, but it's worth the effort.
Start touching and holding your dog's paws regularly—not just when trimming. Handle their toes, press gently on the nails, separate their pads. Make it part of your normal routine when you're relaxing together. Pair this with treats and praise so they associate paw touching with good things. (This kind of handling practice is also taught in puppy training classes—it makes grooming visits much easier later.)
The PDSA emphasises that dogs should be relaxed and comfortable before you start any nail work.[2] If they're already anxious when you pick up the clippers, you're starting from a difficult position.
Let your dog sniff the clippers or grinder. Reward them for staying calm around the tool. For grinders, turn it on in another room first so they hear the sound at a distance. Gradually bring it closer over several sessions before you actually use it.
This desensitisation process can take days or weeks—don't rush it. A few minutes of training spread over a fortnight will save you years of wrestling matches.
You don't have to do all four paws at once. If your dog gets stressed, trim one or two nails and stop. Give treats, praise them, and try again tomorrow. Building positive experiences matters more than finishing the job in one go.
Dewclaws are the "thumb" nails higher up on the leg, and they're easy to overlook. Because they don't touch the ground, they never wear down naturally. Left unchecked, dewclaws can curl around and grow into the pad—painful and requiring veterinary attention.
Check them regularly and include them in your trimming routine.
Always have styptic powder ready before you start trimming. If you nick the quick, press the powder onto the nail tip to stop the bleeding. It works within a minute or two in most cases.
No styptic powder? Cornstarch or plain flour can work in a pinch—press it firmly against the nail and hold for a few minutes. PetMD recommends dabbing the nail on a bar of soap as another emergency option.[6] These alternatives take longer to stop bleeding than proper styptic powder, but they'll get the job done.
If bleeding doesn't stop after 10-15 minutes despite your efforts, contact your vet for advice.
Most dogs need their nails trimmed every 3-6 weeks. Vets generally recommend checking every 4-6 weeks as a baseline, though this varies depending on how much your dog walks on hard surfaces.[7]
Dogs who regularly walk on pavements and concrete naturally wear down their nails, so they may need less frequent trimming. Dogs who mainly walk on grass or stay indoors will need more attention.
If you're trying to encourage an overgrown quick to recede, trim weekly. Preventive Vet notes that trimming every week or two leads to better results, less stress, and shorter sessions overall.[8]
Home trimming isn't always the answer. Sometimes it's better to hand the job over to someone with experience and proper equipment.
Consider booking with a groomer or vet if:
Professional groomers handle nail trims daily. They know the techniques, they've seen every temperament, and they can manage anxious dogs with proper restraint methods. For dogs with severe anxiety, vets can provide mild sedation to make the process safer and less traumatic. Not sure what to ask when booking? Our questions to ask your groomer guide covers what matters.
Looking for a local groomer who offers nail trimming? Our Folkestone groomer guide and Hythe directory list trusted options in the area. Most groomers offer nail trims as a standalone service—typically £5-15—if you don't need a full groom. (See our dog grooming prices guide for typical UK costs.)
Neither is universally better—it depends on your dog and your confidence level. When comparing a nail grinder vs nail clipper for dogs, grinders are generally safer for beginners because you remove nail gradually, reducing the risk of quicking. They're also preferred for dogs with dark nails where the quick isn't visible. However, dog clippers vs grinders have their own advantages: clippers are faster, silent, and work better for dogs who dislike vibration or noise. Many professional groomers use both: clippers first for speed, then a grinder to smooth edges.
The nail will bleed and your dog will feel pain, but it's not dangerous if handled properly. Apply styptic powder (or cornstarch/flour as alternatives) with firm pressure for a minute or two. The bleeding should stop. Keep your dog calm and reward them so they don't develop lasting fear. If bleeding continues beyond 10-15 minutes, contact your vet. The quick heals, and while your dog may be wary next time, one accident won't cause permanent trauma if you handle it calmly.
The easiest test is sound: if you can hear clicking on hard floors, the nails need trimming. When your dog is standing, their nails shouldn't touch the ground. If they're pushing the toes up or to the side, or if you can see them curving, they're overdue. Long nails alter your dog's gait and put strain on joints—address them sooner rather than later.
Yes, for smoothing rough edges after clipping. A standard emery board works fine for light filing, though it won't remove much length. For actually trimming nails down, you'll need proper clippers or a grinder designed for dogs—human tools aren't built to handle the thickness and curve of canine nails.
Start with desensitisation, not nail trimming. Handle your dog's paws daily during relaxed moments—while watching TV, after walks, whenever they're calm. Reward them for tolerating it. Once they accept paw touching, introduce the tools without using them. Let them sniff, reward calm behaviour, and build up slowly over days or weeks. If your dog remains extremely anxious or aggressive, book a professional groomer who has experience with nervous dogs, or ask your vet about anxiety management options.
