What this means for your Estrela Mountain Dog
Hip dysplasia is a concern given the breed's substantial size, so watch for stiffness or reluctance to move as your Estrela ages. Generally considered a hardy guardian breed, having been shaped by centuries of working outdoors in demanding mountain conditions.
As a naturally protective breed, early socialisation matters throughout life, and this becomes especially relevant as senior dogs may become more set in their routines and territorial habits.
When is an Estrela Mountain Dog considered a senior?
Under The Royal Kennel Club's size-adjusted guidance, large breeds like the Estrela Mountain Dog are generally considered senior from around 5 dog years old.
