Cheyenne, WY – State officials are urging residents to use pesticides properly and report any missing supplies in light of a recent string of dog poisonings in northwestern Wyoming. At least 21 dogs in Wyoming and Idaho have been sickened or killed since March. The dogs ate hot dogs filled with the insecticide Temik, a granular substance that looks like black table salt. Wyoming Department of Agriculture officials says the insecticide is used to control nematodes in Wyoming's surgar beet fields. Investigators believe the poisoned hot dogs were meant for wolves, not pets. A 20 thousand dollar reward is being offered in the case.
