My Yorkie threw up yesterday afternoon and again last night...and it was probably everything he had eaten for the day. He also has gas and his tummy is rumbling, He acts like he feels OK, not quite as playful, but it's very hot here...98-100 degrees, so he's been laying around inside instead of running in and out. Also, he gets car sick! I can't take him anywhere. Is there something I can give him to settle his stomach? Pepto-Bismol? What about taking him in the car? Will little trips at a time help to get him used to it?
