What is the cause of patchy hair loss on a dog's body?

Patchy hair loss on a dog's body may be caused by improper bathing, improper diet, external parasite infection, or skin diseases. Therefore, owners need to carefully observe whether their dogs are scratching their skin, and whether there are symptoms such as dandruff, ringworm, eggshells, feces, etc. on the skin. If so, it is more likely to be caused by skin diseases, and it is recommended to take the dog to a pet hospital immediately for inspection to determine the specific pathogen, and then choose the corresponding medication. In addition, when raising dogs normally, attention should also be paid to ensuring a balanced diet to improve the dog's skin resistance.

Improper bathing

The skin pH of dogs and humans is different. Many components in human shampoos are irritating to dogs, which can cause symptoms such as hair loss, itchy skin, dandruff, and dull hair after use. Moreover, if owners frequently bathe their dogs, they will destroy the dog's skin protective layer, making the skin sensitive and fragile, and the hair rough and easy to fall off. Therefore, owners must use pet-specific shampoos to bathe their dogs, and control the frequency of bathing, not washing too often. Generally, it is recommended to limit the number of dog baths to 2-3 times a month, and dry the dog's fur promptly after bathing to avoid catching a cold or getting skin diseases.

Improper diet

If a dog's usual diet is monotonous or the owner habitually feeds the dog human food, it can cause patchy hair loss on the dog's body. Therefore, owners should pay attention to the dog's nutritional balance in daily life and feed the dog more foods beneficial to hair nutrition, such as chicken, beef, salmon, carrots, and broccoli. In addition, it is necessary to cook the food lightly and choose low-salt dog food.

External parasite infection or skin disease

If a dog is infected with external parasites or has a skin disease, it will constantly scratch itself due to itching all over the body, resulting in large patches of hair loss. Therefore, owners must regularly deworm their dogs both internally and externally to reduce the breeding of external parasites and thoroughly eliminate them. As a result, the dog's skin condition will gradually improve.
