My dogs don’t have squeaky hamburgers or plush squirrels. They don’t wrestle with rope toys or frisbees. They work with what they have, and that is 2 acres of free sticks. The trees drop them all the time, and if they finish chewing the ones that fell down during the last storm they just go drag a couple branches off the brush pile and vwalah! Even though there’s 2 whole acres of sticks…they still only want the one that is in their sister’s mouth.
