I agree on the raccoon scat.
Reference dogs and berries. Every dog I have owned for the last twenty years has been a voracious eater of berries. Whether they are blackberries, blueberries, thimble berries or salal (native berry to the PNW) the dogs will go out and pick them and eat them. The native berry bushes are not a problem but the domestic blueberries I have to keep fenced to keep the dogs out of them. When the young dogs see the older ones picking and eating the blackberries they learn quickly how to avoid the thorns. It is comical to watch them learn to pick them carefully with their mouths so as to avoid the thorns. Very methodical unlike the salal where all you see are bushes shaking as they dive in an gorge themselves resulting in a purple poop. Salal berries were actually used by the Indians to tighten up the stools of their young so no loose dog droppings.
