Special Considerations

Due to their large size and protective nature, it is crucial to provide early and consistent socialization and obedience training for this breed.

It is crucial for owners to provide proper training and socialization from an early age to help channel and manage their natural protective instincts in a positive and constructive manner.

Allergies and Shedding
