What causes hair loss on dogs?

Causes of dog hair loss:
1. If the dog is infected with parasites and the nutrients are absorbed by the parasites, hair loss will occur, and timely treatment is required. It repels insects.
2. If your dog eats some spicy or salty food, it will also cause hair loss. You need to avoid feeding it any food with seasonings.
3. If a dog is fed a single diet for a long time, it will suffer from nutritional deficiencies and hair loss. Feed it rich foods such as cooked egg yolks, chicken breasts, fruits and vegetables.
4. If you use human shower gel or soap to bathe your dog for a long time, it will also cause it to lose hair, so you need to bathe it with pet bath products.
5. If you bathe your dog frequently, it will damage the skin and cause hair loss. You need to reduce the frequency of bathing.
