Pedigree dogs are becoming stupid

Pedigree 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.

Report author Kenth Svartberg, an ethologist from Stockholm University, said the changes had happened over the course of just a few generations. "Modern breeding practices are affecting the behaviour and mental abilities of pedigree breeds as well as their physical features," he said.
