Pedigree dogs are becoming stupid as we breed them for looks, not brainsPedigree dogs have become increasingly stupid as they are now bred for their looks, not their brains, according to new research.
Their mental and physical agility of many breeds is being eroded as owners now look for docile, pretty pets to live in their homes.
In the 19th century dogs were more likely to be selected for their strength and skills, so they were able to earn their keep guarding homes and livestock and fetching the quarry on a hunting trip.
But a significant change in breeding trends has meant the ancestors of these proud working dogs are now less responsive to commands and not as alert or attentive.
Scientists in Sweden have found strong evidence that breeding for appearance has led to a decline in intelligence.
