The dog’s hair shedding

External parasitosis

The presence of fleas is a common reason for hair loss, especially in specific areas, such as the end of the back and the beginning of the tail. Sometimes it is possible to detect these parasites, but sometimes we will only see alopecia, wounds or a grit that corresponds to the flea droppings.

In addition, many dogs suffer from what is known as flea bite allergy dermatitis. In them a single sting triggers a picture like the one described, but aggravated. The vet will have to treat these symptoms and schedule regular external deworming, which is the best prevention.

Skin diseases that cause bald spots

Also, there are other diseases, such as allergies, that can lead to hair loss. Its main symptom is itching. It is the intense scratching that the dog starts to alleviate which causes the hair to end up falling out. Allergies should also be treated by the vet. Its resolution can be complex.
