Copyright © 2015 Albuquerque Journal They have names like Pappy, Taz and Smokey – pleasant names to make them better candidates for adoption. But these and dozens of other dogs adopted out of the city of Albuquerque’s animal shelter last year have something else in common: They have killed and maimed other pets, bitten children, attacked their handlers or displayed other signs of aggression. In more than 100 cases last year, the Albuquerque Animal Welfare Department has allowed the dogs to be adopted by families or returned to their owners even though they flunked nationally recognized standardized tests that showed the animals had dangerous tendencies. One dog was so aggressive he couldn’t be tested, but was still adopted out.
