Dog treats from China are apparently still killing American animals, according to the government.

FOX's Jill Nado has more from Washington:

Over 1100 dogs have been killed after eating tainted jerky, with ingredients made in China. The Food and Drug Administration has been investigating since 2007 and they still don't know why the treats are fatal. But they do say the complaints are still coming in.

The latest reporting period covers September of 2014 through the end of 2015 with 200 complaints of animals getting sick and that's on top of the 5,000 they already had.

The agency says the flavors producing the most concern are chicken, duck and sweet potato jerky.
