What is alopecia in dogs?

Alopecia, also known as hair loss, is a very common condition in dogs. Unlike hair loss, alopecia is a normal part of a dog’s hair growth cycle and depends on the breed of the dog. Alopecia refers to hair thinning or patches of hair loss (bald spots). Where hair loss occurs may depend on the underlying cause.

Symptoms of Hair Loss in Dogs

Depending on the cause of the alopecia, there may be accompanying symptoms which include:
Minor to severe scratches (but sometimes no scratches)
Red, inflamed, thickened, oozing, oozing, foul-smelling, or pigmented (black) skin
Skin with papules (red spots), pustules (pustules), plaques or hives.


If alopecia is caused by parasites, it can be visible or invisible. Fleas and ticks can be seen with the naked eye. Mites and fungal elements such as ringworm cannot be seen. Dogs often traumatize their skin due to excessive rubbing, resulting in open wounds. Many dogs will have other affected areas, such as the ears and feet, especially those with some allergies.

How Veterinarians Diagnose Alopecia in Dogs

A thorough physical examination by the vet is the most important step in diagnosing the cause or causes of alopecia. It is rarely a quick fix when it comes to skin disorders in dogs.

Scratches on the skin (for demodectic or scaly scabies)
