There could be many reasons why your dog might experience hair loss. These reasons range from allergies and seasonal shedding to more severe reasons like alopecia. Today, our Orange Park vets what causes patches of hair loss in dogs.
What Causes Dog Hair Loss?
There can be many reasons why your dog might have patchy hair loss. These include regular, seasonal shedding, mange, fleas or other kinds of mites, and even hormonal changes. Of course, there is also alopecia to be careful of too.
Brushing your dog twice a week can aid in the removal and reduction of unwanted hair. Dogs shed their fur when their hairs become worn or damaged, or when the weather warms up. For example, huskies and labradors have thick winter undercoats that they shed in the spring. Seasonal shedding is frequently reduced if you live in a temperate climate.
Dogs, like humans, can get bacterial or fungal skin infections. Pyoderma is a bacterial skin infection that manifests as red and pus-filled skin. Candida infections, also known as yeast infections, occur when the yeast found on a dog's skin overgrows. Ringworm, also known as tinea, is a fungus that causes dry skin and hair damage in circular areas.
Mange is a term that refers to itchy skin conditions caused by mites. Mites are microscopic organisms that live on the surface of the skin or in hair follicles. Scabies mites, for example, are highly contagious to humans and other dogs. If you find mites or fleas on your dog, consult your veterinarian about an antiparasitic treatment.
Dogs, like humans, can develop allergies, with itchy skin and hair loss being the most common symptoms. The most common allergies in dogs are to irritants such as pollen, mold, dust mites, flea allergies, and food allergies. However, dietary allergies can only be detected after at least eight weeks of food trials.
Other Medical Conditions
Stress, poor diet, pregnancy, nursing, or any underlying medical condition can all cause excessive shedding. Even if his illness is usually treatable with a simple diet or medication change, a dog who is losing hair should see a veterinarian. They will make a recommendation for dog hair loss therapy based on your pet's other health requirements.
Alopecia is a relatively common condition. It refers to either thinning hair or areas of hair loss (bald spots). This is distinct from shedding, which is a natural part of your dog's hair development cycle and varies by breed.
