I have a cockapoo, that i got a few months ago, Very Active and healthy. Today we went for a daily walk, (well, not on those cold cold days) and he seemed fine all day. now he is shivering and lying down, I covered him up and he seems to be sleeping, but still shivering. Do dogs get sick like people? Like maybe he has a fever and shivering, but doesn't seem hot to the touch. Can animals take tylenol? I don't want to give him anything that will hurt him, but maybe a little childrens tylenol would make him feel better? Ive had dogs before but dont remember them actually seeming sick. I knew something was wrong when he wasn't following me all around. TIA
