@space007,
What kind of people are you hanging out with?
It's is not safe to shave pets. They'll get sunburned, or you'll accidently cut them if they are not staying still. Cutting the hair and maybe leaving half an inch to an inch of hair on the skin is better. It's recommeneded to go to a professional dog groomer to do this.
Animal coats are evolved to keep them warm in winter and cool in summer, and it is like a built in temeprature control for the pet.
One of my friend has a husky who hates the summer, but she doesn't shave of the fur, but just opens up her pool. So whenever the doggy feels hot, it dives into the pool.
If you don't have a pool, just buy a snap-set pool. It's cheap and a good investment for a pet.
