Another thing to watch is that now without his coat he will actually get HOTTER faster instead of staying cooler like most people think. A dog's fur insulates them from both the cold AND heat.
I remember reading about how in WW2, one of the armies took Dobermans to the South Pacific theater because they thought the GSD's would not do well in the heat, with their thick coats. It turned out the GSD's did just fine, and the Dobermans suffered because of their black color and thin coats.
