The booties probably would protect his dewclaws as long as the fastener came up high enough to go over them. The only problem might be if your dog's dewclaws are the big double-ugly ones. Those are the ones most susceptible to being ripped while running through brush.

If he rips one and has to go to a vet for repair, ask to have the other one removed, too. Under anesthesia is better than out on a day hike, with the blood pouring out and you with nothing to bandage it with. <img src="/images/graemlins/frown.gif" alt="" />
