The family of a teenage boy sprayed by a cyanide explosive that killed their dog is outraged they weren’t told the device was planted near their home, reports East Idaho News.

Canyon Mansfield, 14, went on a walk Thursday afternoon with his family’s 3-year-old yellow Labrador, Casey, on a hill behind their Pocatello home on Buck Skin Road.

“I see this little pipe that looked like a sprinkler sticking out of the ground,” Canyon told EastIdahoNews.com. “I go over and touch it. Then it makes a pop sound and it spews orange gas everywhere.”

The Mansfields said, as of Friday, nobody from the US Department of Agriculture has contacted them to apologize for what happened.
