Oh, those zoomies in the house are dangerous.....outside this evening he was running so fast he finally just crashed on the ground panting....we solved the zoomie problem for tonight. He is so good & never runs off the farm without a leash but Sophie always needs a leash so I boughtba 30 ft one to give her as much freedom as possible while I still have final control. Aussie energy is exhausting when not feeling 100% healthy
