Facts about the Spanish Mastiff

Exercise

Working breeds thrive with a job — 60+ min activity plus mental tasks prevent destructive boredom.

AKC

Behavior

Deeply bonded to their handler — early socialization prevents separation anxiety and over-protectiveness.

VCA

Health

Large-breed puppies: avoid long runs until 18 months. Growth plates close late — early high-impact harms joints.

VCA

Training

Consistency is non-negotiable — the same command from every family member, every time. Mixed signals breed confusion.
