What You'll Learn
Fungal or bacterial infections
Black nails in dogs can be a sign of a fungal or bacterial infection. This is one of the most common reasons for discolouration, along with trauma to the nail or toe, a detached nail, ageing, allergies, growths, or tumours. In rare cases, it can indicate an autoimmune disease.
If your dog has black nails, it is important to monitor their behaviour and look for any other potential symptoms. If you are concerned, it is always best to consult your veterinarian for a proper diagnosis and treatment plan.

Trauma to the nail or toe
If your dog has black nails, it is important to monitor their behaviour. For example, are they chewing or licking the infected area? Are they showing any other signs of discomfort? If so, it is highly recommended to visit your vet.
It is also important to note that nail discolouration can be benign, such as a normal change in pigmentation. However, as a pet owner, it is always better to be safe than sorry. If you are unsure about the cause of your dog's black nails, it is best to seek the advice of a professional.
In summary, while trauma to the nail or toe can cause a dog's nail to turn black, it is important to be aware of other potential causes and to seek veterinary advice if you are concerned.

Detached nails
If your dog's nail is detached and black, it could be due to a few reasons. Firstly, it could be a sign of trauma to the nail or toe, such as an injury sustained during play or exercise. In such cases, the nail turns black due to a blood bleed underneath or because the nail is dying and will fall off as it separates from the nail bed.
Another possible reason for a detached, black nail is a fungal or bacterial infection. This is characterised by dark spots or discolouration on the nail, and the dog may chew or lick the affected area. Ageing, allergies, and, in rare cases, autoimmune diseases can also cause nail discolouration.
While nail discolouration can sometimes be benign, it is important to consult your veterinarian, especially if the colour change is sudden. They can provide an expert opinion and rule out any serious underlying conditions.

Ageing
While black nails in dogs can be caused by a number of factors, ageing is one of the most common causes. As dogs get older, their nails may start to change colour, turning black. This is a natural process and there is usually nothing to worry about. However, it is important to keep an eye on your dog's nails as they age, as a sudden colour change could indicate a more serious problem.
Fungal or bacterial infections can cause black nails in dogs, and older dogs may be more susceptible to these infections. Symptoms of a fungal infection include dark spots or discoloured nails, as well as your dog chewing or licking the infected area. If you suspect your dog has a fungal or bacterial infection, it is important to take them to the vet for treatment.
Trauma to the nail or toe can also cause black nails in dogs. This could be from an injury, such as hurting their foot during a swim or digging a hole. In these cases, the nail may turn black due to a blood bleed underneath, or because the nail is dying and will fall off. Again, older dogs may be more prone to injuries as their bodies become more fragile.
While less common, black nails in dogs can also be a sign of allergies, growths, tumours, or even an autoimmune disease. If you notice any other symptoms alongside the black nails, such as changes in appetite or energy levels, it is important to consult your vet to rule out any serious underlying conditions.
Overall, while black nails in dogs can be a normal part of ageing, it is always best to monitor your dog's nails and seek veterinary advice if you have any concerns. Regular nail trims and good nail hygiene can also help to keep your dog's nails healthy as they age.

Allergies
Black nails in dogs can be caused by a number of issues, including allergies.
There are a number of potential allergens that can cause nail discolouration in dogs. These include environmental allergens, such as pollen, dust, and mould, as well as food allergens, such as wheat, corn, and soy. In some cases, dogs can also develop allergies to ingredients in their shampoo or other grooming products, which can lead to nail discolouration.
If your dog is experiencing nail discolouration due to allergies, there are a few things you can do to help manage the condition. First, try to identify and eliminate any potential allergens from their environment or diet. This may involve switching to a hypoallergenic diet or using allergy-friendly grooming products. You can also try giving your dog supplements, such as omega-3 fatty acids, to help reduce inflammation and improve nail health.
In some cases, allergies may be managed through immunotherapy, which involves exposing the dog to small amounts of the allergen over time to build up their tolerance. This treatment should always be supervised by a veterinarian, who can advise on the best course of action for your dog's specific needs.
