Poor baby. Bathe the little guy. When I got Josie she was 13 weeks and she had pooped and thrown up on herself from the airplane ride. I immediately gave her a bath. Get a little tub fill it with warm water and use a tearless baby shampoo. Talk to him in a soft voice the whole time. Have a warm towel from the dryer in a plastic bag so as it stays warm and he will be just fine. Keep him in the towel all warm and secure till he seems okay maybe 15-20 minutes, then gently warm blow dry. He'll probably be a little scared but, he'll eventually get used to it. Good Luck!
