Should you shave your dog who has mange?

I personally wouldn't shave a dog just for that reason. Shaving them won't get rid of the fleas. You'll need to get a special shampoo from your vet and wash them in that and then comb all the fleas out. You may have to repeat the process. Also, you should buy some flea spray from a Wal-Mart or some similar store to spray on the dogs bedding. :)
