My Rain-hating Puggle

Ever since I got my puggle he has completely despised the rain. As soon as we walk outside and it is raining he immediately turns around to go back inside. Since we still have to go for a walk, Puggles will walk ever-so-painfully slow along the side of the building to avoid getting wet. If by chance he does get wet, he stops and looks at me pitifully.
If Puggles was a normal dog I could buy him a cute little raincoat and call it a day. Unfortunately, he freaks out whenever we try to dress him in anything (sweater, raincoat, costumes etc). If I had started dressing Puggles as soon as I got him, he would probably be more acceptant of doggie-clothes.
