Their size, strength, and trainability made them indispensable in tough conditions, such as the snowy passes of the Alps (Saint Bernard) or the hunting grounds of ancient Europe (Irish Wolfhound).
Selective breeding since the 19th century has increased not only the size of these breeds but helped shape the calm, stable temperaments we admire today.

Despite their intimidating presence, giant dogs are typically known for three core traits:
- Loyaltyâthey bond closely and are fiercely devoted to their families.
