Farmers in the Canary Islands, especially on Tenerife and Gran Canaria, developed the Presa Canario to guard property and to catch and hold cattle. Its name roughly means Canarian catch dog. The breed came close to disappearing in the mid-twentieth century before enthusiasts revived it, and the American Kennel Club now records it in its Foundation Stock Service rather than granting full recognition. Presas are massive, muscular mastiffs with a broad, square head, a short coarse coat and a calm, watchful expression.
With their family, many Presas are steady and devoted, but the breed's guarding instinct is strong and suspicion of strangers is typical. Some are intolerant of other dogs, particularly of the same sex. This is a dog for an experienced adopter who will invest in socialization, consistent reward-based training and secure management for life.
