Prince Albert firefighters rescue Chihuahua from home's heating system PRINCE ALBERT, Saskatchewan, Jan. 13 (UPI) -- Emergency responders in Saskatchewan said firefighters dismantled portions of a home's heating system to rescue a tiny puppy that fell into a vent. Prince Albert Battalion Chief Curtis Mickelson said the owners of Chihuahua puppy Yoshi called authorities Saturday and reported the dog had made his way into the duct work of the heating system and had been trapped for about an hour, the Canadian Broadcasting Corp. reported Monday. "The little puppy was playing and fell into one of the heating vents ... an uncovered heating vent," Mickelson said. He said firefighters disassembled a portion of the heating system to rescue Yoshi, who did not appear to be seriously injured.
