The study involved data on 264,000 U.K. dogs, and the results underscore the importance of training dogs and educating owners, the researchers said. They said the large number of misbehaving dogs that are euthanized also highlights a need for improved behavioral education for veterinarians so they can better assist pet owners.

The study was published Tuesday in the British publication Animal Welfare.
