A little introduction

The Pyrenean Mastiff is a large and powerful breed of dog from the Pyrenees Mountains of Spain.

Everyday life

Energy & play

Coat & grooming

Medium, Double coat. Brush regularly and check for tangles, especially around ears and legs. Introduce handling slowly with rewards.

Food & feeding

Choose complete and balanced food suitable for large-breed puppy growth. Measure meals using the food label as a starting point, then adjust with your vet as your puppy grows. Fresh water should always be available.

Learning together

Use short reward-based sessions, patient repetition and a predictable routine. Find what motivates your individual puppy.

Play, comfort & little quirks

Things to try together

Try sniffing walks, easy food puzzles, gentle play, and a cosy place to nap near the family. Let your puppy choose how to join in.

When to give them space

Watch for avoidance of loud surprises, rough handling, overwhelming greetings, or play that goes on too long. Each puppy has their own comfort zone.
