River Rock vs Pea Gravel for Dog-Friendly Backyards in Arizona

For an 85-lb dog, pea gravel (⅜ inch) is far safer and more comfortable than ¾–1½ inch river rock. Install 4 inches of pea gravel over 4 inches of compacted crushed granite fines. River rock is acceptable for human use but can bruise paws and shift under weight. Both reduce maintenance compared to sod.
