A drug used to euthanize animals has been found in the Evanger’s dog food brand, triggering a recall after one dog died and five others became ill. The cans were sold in 15 states and were manufactured from June 6 to 13. The drug, pentobarbital, is used to put down animals. Evanger’s severed its ties with the supplier. “We feel that we have been let down by our supplier, and in reference to the possible presence of pentobarbital, we have let down our customers,” the company said, adding that it is paying the veterinarian bills for affected dogs.
