Care Essentials
Giant dog, gentle needs — here is the daily reality. Training should start early, and the short lifespan is the heartbreak: go in with open eyes.

Grooming

Bathe as needed. Trim nails, check ears, brush teeth regularly. Wipe the jowls constantly.

Exercise and Enrichment
Low to moderate energy: aim for 30 to 45 minutes of moderate activity daily. The Saint Bernard dog enjoys gentle exercise.
