Heritage & Purpose
Spanish Mastiff
Origin:
Medieval Spain saw these mastiffs guarding livestock against wolves and bears in the Mesta system. Their impressive size and protective nature made them invaluable guardians of sheep flocks.
Shetland Sheepdog
Origin:
Developed in the Shetland Islands during the 1800s, these dogs were bred to herd sheep and small livestock across rugged terrain while being compact enough to maintain on limited resources.
Special Considerations
Spanish Mastiff
Regular grooming needed during shedding seasons. Moderate exercise requirements must be met consistently. Health monitoring is essential due to size-related issues.
Shetland Sheepdog
Regular grooming sessions needed for double coat maintenance. Requires early socialization to prevent shyness. Tendency to bark needs early training attention.
