Can A Dogs Nail Fall Off And Grow Back?

Dog nails serve important functions like protecting the toes, providing traction, helping dig, and more. However, nail injuries or damage do occasionally happen. When a dog’s nail falls off or gets torn off, it can be alarming and concerning for pet owners. The good news is that yes, a dog’s nails can and do grow back after being damaged or lost. In this article, we will cover the anatomy of dog nails, what happens when a nail falls off, how long it takes to regrow, proper care for the nail bed, potential complications to watch for, when to seek veterinary care, and how to prevent nail injuries from occurring.

Anatomy of Dog Nails

A dog’s nail consists of several parts that all serve an important function. The main components are the nail bed, quick, and nail matrix.

The nail bed is the soft tissue from which the nail originates and grows. It contains nerves and blood vessels that supply the nail. The quick is the living part inside the nail that contains nerves and blood vessels. It’s the pinkish area within the nail. As you trim the nail closer to the quick, you will see more of it which helps avoid hitting it. The nail matrix sits at the base of the nail and produces new nail cells that push outward as the nail grows longer. This is why nails grow continually throughout a dog’s life (Source).

Understanding the anatomy helps ensure proper nail care. Knowing where the quick is prevents trimming too short and causing pain and bleeding. Being aware of the nail matrix shows that trimming doesn’t stop nail growth. Proper nail care requires regular trimming to avoid issues as the nails grow.

Causes of Nail Loss

There are several potential causes of nail loss in dogs:

Trauma or injury is a very common cause of nails falling off. If a nail gets caught on something and pulled hard enough, the entire nail can detach from the nail bed. This often leads to bleeding as the quick is exposed. According to MedVet, tearing off a nail may require veterinary treatment to stop bleeding and prevent infection [1].

Bacterial or fungal infections can also cause nail loss. If the nail bed becomes infected, the infection can damage the nail matrix and lead to the nail detaching. Underlying skin conditions like pododermatitis can allow bacteria access to the nail bed and lead to infection [2].

Autoimmune diseases like lupus, hypothyroidism, and Cushing’s disease can sometimes cause nails to weaken, detach, and fall off over time. The immune system attacks the nail structures, leading to detachment.

Nail tumors or cancers like squamous cell carcinoma, malignant melanoma, or mast cell tumors are also potential causes of nail loss in dogs. As the tumor grows, it can disrupt the nail unit and lead to shedding.

What Happens When a Nail Falls Off

When a dog’s nail falls off either partially or fully, the nail bed underneath is exposed. The nail bed contains blood vessels and nerves and is very sensitive. When exposed, the nail bed may bleed and be painful for the dog.

The damaged part of the nail bed will dry up and harden over the next several days, forming a scab-like layer, similar to a scab over a skin wound. This protects the sensitive nail bed underneath as the nail starts to regrow. The dried nail bed will eventually fall off on its own after a week or two as the new nail grows in and pushes it off.

During this time, it’s important not to pull or peel the dried nail bed off, as this can disturb the new nail growth and cause bleeding. Allow it to fall off on its own. The new nail will start growing from the nail matrix at the base of the nail bed within a few days. It takes several weeks to months for the nail to fully regrow depending on the dog’s age and health.

Keeping the area clean and protected while providing pain management if needed will help ensure proper healing and regrowth. Monitor for any signs of infection and see the vet if the nail bed appears very inflamed, oozing pus, or not healing properly.

Regrowing the Nail

When a dog’s nail falls off or is torn off, a new nail will begin growing to replace it. However, regrowth time can vary quite a bit depending on the individual dog and circumstances. According to Wag Walking, most nails take 2-6 months to fully regrow after being torn off or falling off on their own.

Some factors that affect regrowth time include:

  • How much of the nail was lost – If just the outer shell came off but the quick is intact, regrowth will be faster than if the entire nail was lost down to the nail bed.
  • The dog’s health and age – Younger, healthy dogs tend to regrow nails quicker than older dogs or dogs with health conditions.
  • Whether there is damage to the nail bed – Deep lacerations or trauma to the nail bed can delay regrowth.
  • Nutrition – Dogs on a healthy diet with nutrients like biotin and methionine tend to see faster nail regrowth.

The new nail will likely start out soft and brittle as it initially grows in. It will take some time for the new nail to toughen up and build strength. Keeping the area clean while the new nail emerges is important to prevent infection.

While waiting for the nail to regrow, it’s a good idea to keep walks and playtime on soft surfaces to avoid impact on the exposed nail bed. Consult your veterinarian if the nail takes longer than expected to regrow or if you notice signs of infection.

Caring for the Nail Bed

If your dog’s nail falls off, it’s important to properly care for the exposed nail bed to prevent infection and promote healing. Here are some tips:

Clean the nail bed gently with mild soap and water or an antiseptic wipe to remove dirt and debris. Be very gentle, as the nail bed will be sensitive.(1)

Apply an antibiotic ointment or powder to the nail bed, as recommended by your veterinarian, to prevent infection. Keep the ointment on the nail bed when changing bandages.(2)

Bandage the paw carefully to protect the exposed nail bed. Use a soft, non-stick bandage and wrapping. Change the bandage daily to keep it clean and monitor healing.

Restrict your dog’s activity to prevent dirt from contaminating the nail bed and to avoid any trauma to the sensitive area.

Follow up with your vet in 2-3 days to monitor healing. Signs of infection include pus, redness, swelling, or your dog licking excessively at the bandage.

Allowing the nail bed to heal properly helps promote healthy regrowth of the nail.

Potential Complications

There are a few potential complications that can occur if a dog’s nail falls off or is ripped off. Some of the main risks include:


The nail bed contains blood vessels and living tissue, so it is prone to infection if exposed (source: Bacteria can easily enter the open nail bed and cause an infection. Signs of infection include redness, swelling, discharge, foul odor, and pain. Infections should be treated promptly with antibiotics prescribed by a veterinarian.

Abnormal regrowth

If the germinal matrix (where nail growth originates) is damaged when the nail falls off, the new nail may grow in abnormally. It may become misshapen, brittle, or grow unevenly. In some cases, the nail may become ingrown if the nail curvature is altered (source: Abnormal regrowth usually requires trimming and monitoring by a vet.

Chronic pain

If the nail quick or any nerve endings are exposed, dogs may experience chronic pain even after the nail bed has healed. Pain management medication may be needed in these cases.

When to See the Vet

In most cases, a dog’s nail will regrow on its own after falling off, but it’s important to monitor for signs of complications that require veterinary attention. Some signs to watch out for include:

Excessive bleeding that does not stop after applying direct pressure. This could be a sign that the nail was partially torn off and the nail bed is still exposed.

Signs of infection like swelling, redness, discharge or a foul odor around the nail bed. Bacteria can enter the nail bed and cause infection.

If the nail was completely ripped off, look for signs that the quick was exposed. The quick contains nerves and blood vessels and damage to it is extremely painful and can cause ongoing complications.

Lameness or limping that lasts more than a day or two. This could indicate a more serious injury like a fracture.

Loss of appetite, lethargy or other signs of discomfort. Nail injuries can be extremely painful.

If you notice any of these warning signs, take your dog to the veterinarian right away. Leaving an infected or seriously damaged nail bed unattended can lead to chronic pain and mobility issues down the road.

Preventing Nail Loss

There are several things you can do to help prevent your dog’s nails from becoming damaged or falling off.

Tips for Nail Care and Safety

Regularly trim your dog’s nails to keep them at an appropriate length. Long nails are more prone to snagging and tearing. Use proper nail clippers designed for dogs and trim just the clear portion, avoiding the quick which contains blood vessels and nerves. If unsure, just trim a small amount at a time.1

File sharp edges after clipping to smooth them out. This helps prevent splits and cracks in the nail.2

Avoid letting your dog run on rough surfaces that could catch or tear nails. Hard surfaces like concrete and asphalt can also wear nails down over time.3

Use paw balms or moisturizers if your dog has dry, brittle nails that are prone to cracking.

Carefully supervise outdoor play to prevent injuries. Keep areas clear of sharp sticks, rocks, and uneven ground.

Get in the habit of inspecting your dog’s paws and nails regularly so you can promptly address any issues.


Broken or lost nails are a relatively common occurrence for dogs. With the anatomy of a dog nail and an understanding of the causes of nail loss, dog owners can be prepared to properly care for their dog’s nail bed and allow the nail time to regrow. While preventative measures can reduce the likelihood of nails breaking or tearing, it’s important to carefully monitor the nail bed for potential complications like infection, and to seek prompt veterinary care if the nail remains painful, inflamed, or fails to regrow.

Overall, broken or lost nails are usually more distressing for owners than dogs. By understanding the nail’s regrowth process, providing proper at-home care, and involving the veterinarian as needed, dogs can regrow lost nails and return to normal, pain-free function within several weeks or months. With attentive care and patience through the regrowth period, owners can successfully manage nail injuries.
