If you have Teddy dandruff, you can use a shower gel with essential oil moisturizing ingredients to bathe your dog to keep the dog's skin moist and avoid dry skin. And don't bathe your dog too frequently, just once or twice a month. That's it. When bathing, the hair should be blown dry to avoid fungal infection, which can also cause dandruff on dogs. Dogs should also be dewormed regularly to prevent skin diseases. In terms of diet, you can give your dog some fruit occasionally to replenish water, and you can also give your dog some hair-beautiful dog food.
