CASPER, Wyo. (AP) — Pit bulls are blamed for killing sheep in Riverton.

Farm owner Bill Jennings says he has found over 50 sheep dead in the last few months. He told KCWY-TV (http://bit.ly/tjP58A ) that he has found dogs in with the sheep twice and put down three dogs.

Capt. Ryan Lee of the Fremont County Sheriff's Office said there seems to be a lot of people that are allowing their dogs to run free. However, he says owners can be criminally and civilly responsible for any damage they cause to livestock.

The Farm Bureau is offering a reward of over $2,000 for information on the sheep attacks.
