Smucker’s has pulled 31 varieties of dog food off store shelves. An investigation found that Gravy Train, Kibbles ‘N Bits, Skippy and Ol’ Roy lines of canned food contained euthanasia drug, pentobarbital.

Retailers have pulled 31 varieties of dog food off shelves and the FDA has begun investigating the matter. Last week ABC News Affiliate WJLA reported that 60% of the food they tested from Smucker’s brands contained pentobarbital.

Smucker’s twitter page is replying back to concerned consumers.
