Why Long Nails Can Hurt Dogs More Than Owners Realize

Overgrown nails are not just a grooming issue. They can put pressure on a dog’s feet, change how they walk, and sometimes lead to painful breaks or infections.

A dog’s nails may seem like a small detail until they start affecting every step. When nails grow too long, they can press against the ground, push the toes out of position, and make walking uncomfortable.

That is why overgrown nails are not just a cosmetic problem. For many dogs, they can become a quiet source of pain that owners may not notice right away.

Dogs use their paws for balance, traction, turning, braking, and reading the ground beneath them. When the nails are the right length, the paw can sit naturally on the floor. When the nails are too long, that normal contact changes.

The result can be more than a clicking sound on tile.

Long nails can change pressure on the foot

One of the simplest warning signs is the sound many owners recognize: nails clicking on hard floors. That does not always mean an emergency, but it can mean the nails are touching the ground more than they should.

When a dog stands or walks with long nails, pressure can shift into the wrong parts of the foot. The Royal Kennel Club notes that long claws can put pressure on the wrong areas of the paw, causing pain and discomfort, and may make a dog move differently to reduce that pain.

That change matters because dogs are built to move with weight distributed through the paw pads and toes. If the nails hit the ground first or force the toes upward, the dog may adjust their stance without obvious whining or crying.

Some dogs slow down. Some avoid smooth floors. Some begin walking stiffly. Others may seem reluctant to jump into the car, climb stairs, or go on longer walks.

Owners may mistake these changes for aging, laziness, or stubbornness. Sometimes, the real problem starts much lower: at the nails.

Pain can build gradually

Dogs often hide discomfort well. A nail that is slightly too long may not cause dramatic symptoms at first. But if the pressure continues, the foot can become sore, especially during running, turning, or walking on hard surfaces.

Overgrown nails are also more likely to catch, split, tear, or break. PDSA warns that nails that become too long can snag, split, or even grow into the pad, which can be painful and may lead to bleeding or infection.

That risk is especially important for dewclaws, the small nails found higher on the inside of the leg in many dogs. Because dewclaws do not always touch the ground, they may not wear down naturally. If they are forgotten, they can curl, snag, or grow into nearby tissue.

Dogs Trust also advises that severely overgrown nails can grow into the pad or surrounding tissue, causing pain and possible infection, and that owners should talk to a vet if nail beds are pushed upward or toes become distorted.

The quick is why trimming needs care

Trimming sounds simple, but many owners are nervous for a good reason. Inside each dog nail is the quick, a sensitive area containing nerves and blood vessels.

Cutting into the quick can hurt and cause bleeding. VCA Animal Hospitals advises trimming about 2–3 mm away from the quick when it is visible, and taking only the very tip when a dog has dark nails and the quick cannot be seen clearly.

That is also why badly overgrown nails often cannot be fixed with one big cut. When nails stay long, the quick may extend farther into the nail. In those cases, gradual trimming is often safer than trying to shorten everything at once.

For nervous dogs, grinders may be easier than clippers, but they still need patience. The sound and vibration can scare some pets. The best approach is usually slow handling, rewards, and short sessions rather than forcing the whole job in one stressful moment.

Not every dog wears nails down the same way

Some dogs naturally grind their nails down by walking or running on rough outdoor surfaces. Others need more help.

Indoor dogs, senior dogs, small breeds, dogs with mobility problems, and dogs that mostly walk on soft grass may not wear their nails down enough. Dogs with unusual paw shape or uneven movement may also wear some nails faster than others.

This is why nail care is not one-size-fits-all. Two dogs in the same home can need very different trimming schedules.

A useful home check is to look at the dog standing normally on a flat surface. If the nails are clearly pushing into the floor, spreading the toes, or making the paw sit awkwardly, they may be too long. Clicking on hard floors can be another clue, though paw shape and nail type vary.

When owners should get help

A simple nail trim can often be handled at home, but not every situation should be. A vet or professional groomer is the better choice if the nail is cracked, bleeding, curled into the pad, surrounded by swelling, producing discharge, or causing limping.

Professional help is also smart for dogs that panic, bite, or cannot tolerate paw handling. Forcing a frightened dog through trimming can make the fear worse and increase the risk of injury for both the dog and the owner.

The bigger lesson is gentle consistency. Nail care works best before nails become a problem. Short, regular maintenance can prevent painful overgrowth, reduce stress, and help dogs stay comfortable on their feet.

A dog does not have to cry to be hurting. Sometimes the first sign is much quieter: a click on the floor, a shorter walk, or a paw that no longer lands quite right.

KEY TAKEAWAYS:

• Overgrown nails can put pressure on the wrong parts of a dog’s paw.
• Long nails may change how a dog stands, walks, runs, or climbs.
• Nails that grow too long are more likely to split, tear, snag, or grow into the paw pad.
• The quick contains nerves and blood vessels, so trimming should be careful and gradual.
• Limping, bleeding, swelling, discharge, or curled nails should be checked by a vet.
