Dog Nails: What's Hiding Under The Surface?

will a dog grow nails under nail

Dog nail care is an important aspect of pet ownership. Dogs' nails grow continuously and need to be trimmed regularly to prevent overgrowth. In some cases, dogs may experience nail injuries, brittle nails, or abnormal nail growth, which can lead to a ripped or torn nail. Understanding the anatomy of dog nails can help owners provide proper care and identify any potential issues. Dogs' nails are made up of a hard outer shell, called the quick, and a softer inner core containing blood vessels and nerves. The quick can be more easily observed in dogs with white nails, appearing as a pink triangle, while in dogs with dark nails, it may be seen from the underside as a softer, crumbly part. When trimming nails, it is crucial to be cautious to avoid cutting the quick, as it can cause pain, bleeding, and potential infection. In the event of a nail injury, it is important to monitor the affected area for any signs of infection and seek veterinary advice if necessary.

Trimming a dog's nails

How to Trim a Dog's Nails

The quick, a section of nerves and blood vessels, runs through the core of a dog's nail. Cutting the quick can be painful for the dog and cause bleeding. Therefore, it is important to avoid cutting this section of the nail. The quick is easier to see in dogs with white nails, appearing as a pink triangle. In dogs with darker nails, the underside of the nail may reveal a softer, crumbly part, which is the quick.

To trim a dog's nails, use dog-friendly nail clippers or grinders. It is recommended to start handling a puppy's paws and trimming their nails from a young age so they become accustomed to the process. Positive reinforcement, such as treats and praise, can help create a positive association with nail trimming. Regular trimming will cause the quick to recede, making it less likely to be cut during future trims.

If you are unsure about trimming your dog's nails, it is best to seek advice from a veterinarian, experienced dog handler, or professional groomer. They can provide guidance on the proper techniques and tools to use, ensuring the safety and comfort of your dog.

The quick

It is important to trim a dog's nails regularly to prevent them from becoming too long and causing discomfort when walking. Dogs' nails grow continuously, and while outdoor play and running on hard surfaces can help wear them down, regular nail trims are often necessary. Trimming a dog's nails can be challenging, especially if the dog is reluctant to have its paws touched or claws clipped. However, it is important to start handling their paws and trimming their claws from an early age to get them accustomed to the process.

Veterinarians can provide guidance on proper nail trimming techniques and offer this service during wellness exams. They can also advise on supplements to support nail health, such as vitamin, biotin, and gelatin supplements. Additionally, maintaining a well-balanced diet with adequate protein, calcium, zinc, biotin, iron, fish oil, and other B vitamins can promote faster nail regrowth and overall nail health.

Dewclaws

The exact purpose of dewclaws is a subject of debate among experts. Some believe that dewclaws help dogs gain traction when they run, especially when turning at high speeds or navigating slippery surfaces. They may also provide stability to the carpal (wrist) joint and aid in climbing trees or holding objects to chew on. In dog sports, dewclaws can help dogs steady themselves on obstacles like the teeter. Certain dog breeds, such as the Beauceron, use their dewclaws for herding and navigating snowy terrain.

In some cases, dewclaws may be prone to ripping or tearing, especially if they are only attached by loose skin. Surgical removal of dewclaws is sometimes recommended by veterinarians to prevent injury, although the value of these surgeries is debated due to the low incidence of dewclaw problems. Additionally, some dog breeds have their front dewclaws removed for aesthetic reasons in the show ring. However, front dewclaws should not be removed unless there is a compelling reason to do so, as they serve several important functions.

Abnormal nail growth

A dog's claws, or toenails, are constantly growing, and they need to be kept trimmed. Wild dogs naturally wore down their claws while running, hunting, and scratching, but domesticated dogs spend much of their time indoors or on soft surfaces, which means their claws do not get worn down. Regular walks on hard surfaces can help to shorten claws, but they may not be sufficient to keep them at the optimal length.

If you notice something unusual about your dog's nails, such as excessive licking or chewing, there may be a problem. Abnormal nail growth can be caused by trauma to the nail, which can lead to infection if left untreated or if the dog licks it excessively. Bacterial infections can also cause crusting of the nails and the surrounding skin. Food allergies or environmental allergies can also cause multiple nails to become infected.

Another cause of abnormal nail growth is a tumour on the paw or nail bed, which can be cancerous and destructive to the affected area. Treatment for tumours may involve surgery, chemotherapy, or radiation.

A bacterial or fungal infection can cause onychogryphosis, a disease characterised by abnormal, excessive, and curving nail growth. If your dog has developed onychogryphosis, you will notice that its claws have grown more than usual and have become curved.

If you believe your dog has nail issues, you should take it to a veterinarian or veterinary dermatologist for a proper diagnosis and treatment.

Tumours and infections

Symptoms

The most common symptoms of a nail infection in dogs include:

  • Persistent licking or chewing of the nails or paws
  • Swelling and redness of the nail and toe
  • Pus draining from the nail or lesions around the nail
  • Limping or favouring the affected paw
  • Pain or tenderness around the nail bed

Diagnosis

If you suspect your dog has an infected nail, it is important to seek veterinary attention. Your veterinarian will carefully examine your dog's paw and nail bed, looking for any signs of trauma or injury. They may also take a swab of the affected tissue to analyse for bacteria or fungi. In some cases, X-rays or an MRI may be necessary to rule out bone involvement.

Treatment

Treatment for a nail infection will depend on the underlying cause and the severity of the infection. Oral or topical medications, such as antibiotics or antifungal drugs, may be prescribed to clear the infection. Pain medications may also be given to reduce inflammation and discomfort. In severe cases, partial nail removal may be necessary to aid healing.

Tumours

Primary nail bed tumours are uncommon in dogs and typically present with signs of lameness associated with a mass. The most common type of nail bed tumour is squamous cell carcinoma (SCC), followed by melanoma, osteosarcoma, soft-tissue sarcoma, and mast cell tumours. Treatment for nail bed tumours may involve surgical amputation of the affected digit, as seen in the case of a 10-year-old Shih Tzu dog with a nail bed keratoacanthoma.

Frequently asked questions

The rate at which a dog's nails grow varies depending on factors such as their individual growth rate, activity, age, diet, exercise, and overall health. Typically, it takes about 4 to 6 weeks for a dog's nails to grow. Regular trimming is essential to prevent pain and discomfort.

The quick is a blood vessel and nerve encased in thick, hard keratin. It can be seen as a dark blue or black vein beneath the nail surface. Cutting the quick can cause pain and bleeding, so it's important to avoid it when trimming nails.

If you notice any unusual behaviour, such as licking or chewing their nails, there may be a problem. Consult a veterinarian or veterinary dermatologist for a proper diagnosis and treatment.

Ideally, a dog's nails should not touch the ground when standing still. If their nails touch the ground when walking, it may be time for a trim. Regularly checking your dog's nails and consulting a veterinarian can help ensure proper nail care.

Yes, tumours or infections can occur in or around the nails. In some cases, these issues may be cancerous or indicative of underlying health conditions. Prompt veterinary attention is crucial for proper diagnosis and treatment.
