Shepherd dog is a very intelligent, active and vigilant dog breed, and it also has a strong sense of territory and predation instinct, and has a keen sense of smell and vision.

The best way to prevent sheepdogs from biting other dogs' fur is to establish correct social training and behavior norms as soon as possible to ensure that they have good social skills and can get along well with other dogs.
