You're absolutely right. The performance per pound is so much greater with dogs. Those packs are great. Just ordered some. Walmart has arctic boots too and all weather paw treatment that protects their paws. Multi-purpose is a must in any survival tool. Dogs certainly encompass that quality. My hound dog daisy is being trained to retrieve, hunt small game, and carry full pack plus a water belt and a small pack that will carry our cat. If we have to bug out on foot and or hunt she'll be an extraordinary tool. Not to mention the effective way she protects our family.
