My Dog’s Nail Turned Black:Nail Diseases

Having a dog implies taking care of it and being aware of any anomaly that its body may present. It is not enough to feed it, bathe it and play with it, it is also necessary to monitor its behavior and pay attention to small details, such as nails.

Trimming our best friend’s nails on a regular basis is very important so that It can carry out Its activities with comfort and full well-being. Specialists assure that special care must be taken in dogs that spend most of the time inside a house or an apartment since these, unlike dogs that spend many hours outdoors, have no ground to wear their nails.

One of the questions we constantly ask ourselves is what the color of each nail of our dog means. According to experts, these can be naturally black, white, or pink without indicating that something bad is happening. However, they highlight that the sudden change in tonality could be a cause for concern.

The drastic change in the color of the nails or one of them is usually a sign of the existence of an infection or the presence of bacteria or fungi as a result of the waste to which the dog is exposed in the street or in the patios; in more serious situations, it may be related to a disease of the immune system or congenital disorders. In either case, the nail becomes increasingly weak and prone to constant breaking, which could be painful and very dangerous.

If your dog normally has nails of a certain color or even combination, don’t worry, it’s part of your best friend’s physiology. On the contrary, if the appearance changes in a matter of days it is important that they go to the vet, not without first being aware that each breed is different.

Dog nail problems and diseases

The area around the nail may become inflamed and the nail itself may deform, taking on an abnormal yellowish to black color. Let’s see in review what are the main pathologies and diseases that can occur to our dog’s nails from breakage to actual infections.

Trauma and ruptures

Being always ‘exposed’ the dog’s nails are often subject to break, to get caught in fabrics or other materials. Usually, the main cause of breakage and trauma is length: we must always remember to cut Its nails!

Foreign bodies

These microscopic bodies penetrate inside the dog’s pads and cause the dog discomfort and irritation. The consequence is that the dog starts licking Its paws nervously and insistently, often worsening the problem.

This way the infection worsens and we can notice difficulty walking, swelling, and irritation of the tissues around the nail. We must immediately contact the veterinarian.

My Dog Has a ​Broken Nail, What to do?


Pododermatitis in dogs is inflammation of the spaces between the toes of the paws. It’s present in other animals and has various triggering causes, primarily trauma. The blow to the area or even the action of a foreign body hitting the nail: glass, shards, thorns, and stones can hit the area in a traumatic way. Other possible causes include: bacteria or parasites, mycosis, allergies, autoimmune diseases, orthopedic problems, and neoplasms.

It often occurs in dogs accustomed to walking in the woods, hunting areas, and wherever they may find obstacles in their path. Dogs engaged in sporting activities, such as hunting, running, or jumping, are not exempt. I’s a frequent pathology and often associated with dermatoses that affect not only the paw area but also other parts of the body.


It’s a skin disease caused by a mite that occurs in a situation of immunodeficiency, whether it’s hereditary or acquired. Also known as ‘red mange’, caused by a mite acting in a localized form. In this part of the body, there is a loss of hair, at the level of the head and legs: from here it starts to extend in a generalized form, caused by a secondary bacterial infection. This form is certainly more aggressive than the first and involves: itching, fever, and swelling of the lymph nodes.


It’s a fungal infection of the keratinized skin area, making the nails brittle and deformed. There are some dogs that are particularly predisposed to this type of infection, such as Yorkshire terriers. On the nails may be seen patches of alopecia with the presence of scales, with folliculitis with papules, pustules, and crusts. These infections can be caused by ticks, thrombicula (woodland mite), and hookworms (Hookworms).

Treatments and remedies for dog nail diseases

When the dog’s nails present these problems, it’s necessary to treat and cure them with some precautions that only our vet can advise us. In some cases, local remedies are not enough, so instead of creams, ointments, and various ointments, we must think about the surgical removal of the nail. This operation can promote drainage and healing. With the use of antibiotics and antimicrobials, it is often possible to prevent and reduce inflammation.

Always consult with your veterinarian.
