There are many reasons why your dog may be growing an extra nail. It could be a result of a bacterial or fungal infection, a metabolic problem, or a disease such as onychogryphosis, which causes abnormal and excessive curving of the claws. It could also be a symptom of a more significant skin issue, or a condition called cutaneous horn, often caused by a papillomavirus. If you notice any unusual growths or changes in your dog's nails, it is important to consult a veterinarian for a proper diagnosis and treatment plan. Regular nail trimming and good nutrition can also help prevent and manage nail problems in dogs.

What You'll Learn
Dew claws
If you notice that your dog's dew claws are growing abnormally, you should take them to the vet. Abnormal nail growth can be caused by a bacterial or fungal infection, or even a parasite. In some cases, it can be a symptom of a more serious disease, such as onychogryphosis, which causes abnormal, excessive development and curving of the claws. Your vet will be able to advise you on the best course of treatment, which may include medication or removal of the nail.
It is important to regularly check your dog's paws and nails for any problems. This will help you detect an issue early on and prevent it from becoming worse. If you notice any unusual behaviour, such as excessive licking or chewing of the paws, this could indicate that your dog is in pain and you should take them to the vet.
Overall, while dew claws are a normal part of a dog's anatomy, they require extra care and attention to ensure your dog's comfort and health.

Nail disorders
Dogs' nails, like human fingernails, grow and must be trimmed regularly. Nails that are not trimmed can curl back and dig into the footpad, causing pain and secondary infection. This is more common in older dogs due to increased thickening of the nail tissue and hardening of the nails.
There are many causes of abnormal nail growth in dogs, including trauma, bacterial or fungal infections, metabolic problems, and allergies. In some cases, abnormal nail growth can be a symptom of a more serious underlying condition, such as a tumour or a chronic disease such as lupoid onychodystrophy, which can cause brittle, deformed, thickened nails, and nail loss.
One specific type of abnormal nail growth in dogs is called onychogryphosis, characterised by abnormal, excessive development and curving of the claws. This condition can be treated with maintenance therapy or, in some cases, removal of the affected nail.
Another possible cause of abnormal nail growth is a papillomavirus, which can cause hyperkeratosis lesions. These lesions can usually be removed, and in some cases, interferon treatment has been successful.
If you notice that your dog's nails are growing abnormally, it is important to consult a veterinarian for a proper diagnosis and treatment plan.

Tumours
In some cases, an extra nail-like growth on a dog's paw could be a tumour. Tumours on a dog's paw typically appear as mass-like growths and can develop anywhere on the paw, including between the toes, on the paw pads, and at the nail bed.
Some common types of tumours that can develop on a dog's paw include melanoma and mast cell tumours. Melanoma is a type of skin cancer that may be more common in dogs with black skin or certain breeds. Mast cell tumours can be red or pink, potentially with a raw surface.
If your dog has an extra nail-like growth that is causing pain or discomfort, it is important to consult your veterinarian for an examination and proper diagnosis. Treatment options may include surgical removal, chemotherapy, radiation therapy, or other medications, depending on the type and extent of the tumour.
It is worth noting that there are other possible causes for an extra nail-like growth on a dog's paw, such as a cutaneous horn caused by a papillomavirus or hyperkeratosis due to uneven wear on the footpad. A proper diagnosis by a veterinarian is essential to determine the best course of treatment.

Hyperkeratosis
The condition is commonly seen in many dog breeds, especially brachycephalic breeds with short muzzles and smooshed-like faces, such as the Dogue de Bordeaux and the Irish terrier. It is often hereditary or genetic but can also be caused by repeat pressure over thin skin, trauma, infectious diseases, or immune-mediated diseases. Age-related hyperkeratosis is also common in senior dogs, as their skin thickens with ageing, especially at pressure points like the elbows.
While there is no cure for hyperkeratosis, it can be managed through various treatments. Topical treatments, such as specially formulated emollient ointments, anti-seborrhea shampoos, and skin-softening products, can help soften the thickened skin and improve comfort. In some cases, affected skin may need to be removed surgically, and antibiotics may be prescribed for secondary skin infections.
It is important to note that hyperkeratosis is rarely a medical emergency, and most dogs with the condition can live long and high-quality lives. However, it is crucial to monitor your dog's comfort and behaviour, as the condition can cause discomfort during walking if the hardened skin cracks or becomes infected. Regular trimming of the nails and dew claws is also important to prevent overgrowth and potential discomfort.

Onychogryphosis
This condition can be the result of various underlying causes, including primary conditions such as Leishmaniasis, an infection caused by protozoan parasites, or Pemphigus vulgaris and Pemphigus foliaceus, autoimmune diseases affecting the skin and mucous membranes. In some cases, onychogryphosis may be idiopathic, meaning that it occurs without a known cause.
To diagnose onychogryphosis, your veterinarian may perform skin biopsies or diagnostic antibody tests. Treatment options will depend on the underlying cause of the condition. For example, if your dog is diagnosed with Pemphigus vulgaris or Pemphigus foliaceus, the treatment will aim to stop the immune system's destructive response. In some cases, surgical removal of the affected claw may be recommended to provide relief from pain and discomfort.
It is important to work closely with your veterinarian and follow their recommendations to ensure the best outcome for your dog's recovery. Proper nail care and maintenance are crucial to preventing and managing nail disorders in dogs. Regular trimming of the dew claws, which do not touch the ground and therefore do not wear down naturally, is essential to prevent overgrowth and potential pain or discomfort.
