A young moose may have towered over a small Yorkshire terrier it recently came in contact with, but it was no match for a dog mom who used her “mom voice” to keep the moose from attacking the Yorkie.Ring security cameras caught the moment Catherine Diehl-Robbins of Anchorage, Alaska, pointed her finger and shouted to scare away a moose that was chasing her beloved dog, Pixel.It all started when she heard Pixel barking. “I hear her barking, like really serious barking,” Catherine explained to KTUU. When she went to investigate, Catherine discovered that Pixel was barking at a moose. Scared for Pixel’s safety, Catherine went into mom mode.“The moose took off after Pixel so that's when I started yelling at the moose,” Catherine said, later adding "That's when I got the 'mom voice,' 'the husband voice,' 'the retired law enforcement voice' — full artillery, lethal weapon here.""Hey hey hey hey. No,” Catherine can be heard saying on the surveillance footage as she waves her finger at the moose.Like a child who knows mom means business, the moose got Catherine’s message. "Next thing I know the moose stops, the dog is gone, and 'Oh all is well,'” she said. “ That worked and I used my 'mom' voice."Thanks to Catherine’s motherly instincts, Pixel came away from the situation unharmed."He did take a forward swipe at Pixel but Pixel's already moved off,” she said, later adding, "I was surprised the moose just stopped — like whoa.”Catherine and her husband, Everett, also worry about hawks and eagles messing with their dog. Catherine, who is also a wildlife photographer, has a message for any moose — or other critter — that might make its way onto her property. “My yard, my rules,” she said.
