Petey taken too young

As my wife and I wandered around the yard Sun morn, Petey followed closely like always. Suddenly he saw or heard something and ran toward the street. We live in AZ so we are always on the lookout for coyotes. This time Petey was too fast. He ran directly at 5 coyotes. We chased the one who snatched him and scared the coyotes away while they tried to take his sweater off. He had a small puncture, a bite on his neck that cut off his air, plus the coyotes shake prey and break their neck. We are devastated. Petey came from a shelter and blessed us for 4 wonderful years. we had planned on 10 more years of hiking and cuddles. PROTECT YOUR PETS. It happened so quickly we never expected it. We are just heartbroken.
