Are Maremmas hard to train?
Yes, Maremma Sheepdogs are a little hard to train. These intelligent dogs are willful and independent, a combo that can make training a little tricky. One helpful hint: Because they bond so closely to their human, it’s best if the pet parent can do the training. A clear, consistent approach that is firm, as well as sensitive, with a lot of positive reinforcement is key for this breed. 
Be patient and expect gradual progress. Training any dog takes substantial time and effort, regardless of breed. Enlisting the help of a profession with experience training guarding breeds can offer some extra support.
