Carrie Mukwonago, WI 8/24/2011 12:50:12 PM Our 30lb 4 month old Chocolate Lab became lethargic and wouldn't eat Monday, took him to the Vet. Next day he was worse was referred to ER Vet ran test found internal bleeding, low white blood count, liver had high counts. Thinks it might be rat poison. He's getting plasma transfusions and Vitamin K....still waiting to hear how he is. We have no idea where or how he found it.
