My dogs have eaten some strange stuff thru the years. At our other house we had lava rock in the landscaping. Roxie and Duke both enjoyed them. Whenever Keith dumps the grill, Brutus and Roxie run for the charcoal. But, I think the strangest, was Duke. He went fishing in the pond one day.The water level was low, He caught a bass and ate it raw. sushi anyone? I had never seen a dog do that. Years ago when I had horses, the dogs considered horse poop quite wonderful.
