The inductees included a young Bijon Frise dog named Sophie from Olds, Alberta, Sophie awoke her owner and alerted her that the woman's daughter had slipped into a diabetic coma in her bedroom.
The second dog inducted was an 8-year-old Chow Chow named Jarod from Genelle, British Columbia. Jarod distracted a charging black bear and allowed its owner and another dog to flee to safety before escaping from the bear.
The only cat inducted was a 21-pound male domestic shorthair named Nemo, which made persistent efforts to awaken a Toronto woman and alert her that her husband had stopped breathing beside her in bed. The man survived.
Purina also honored Ace, a Dutch-Shepherd mix adopted by a police officer in Hamilton, Ontario, who trained him as a search and rescue service dog. In December, Ace located a woman missing for three days during a major snowstorm. She was buried in snow, but recovered.
Since the inception of the Hall of Fame in 1968, 117 dogs, 24 cats and a horse have been named as heroes for their life-saving deeds, Purina said in a release.
