Dogs with black crusts on their hair roots are generally fungal infections, and this can be bathed with medicated bath shampoos to avoid aggravating the dog’s skin condition. You can take your dog to the vet for an examination to see if it is a dermatological problem or due to natural pigmentation. For natural pigmentation, there is no need to take action and it will not affect your pet’s life. But if it is due to skin disease, you need to diagnose the cause and take targeted treatment to restore your dog’s health.
