I know the theory, in that I trained Jas to lie down by putting him in a sit and then lowering a treat to the floor in front of his nose. It took him a few goes, but he got it fairly quickly. Problem is, the pup doesn't seem to want to keep his bum on the ground. He sits, gives the paw and recalls beautifully, but down is just not happening. He follows the treat with his nose and ends up with his nose on the floor and his arse in the air. I persevere, and he continues to waggle his bum around while wiping his face on the floor trying to get the treat. Or, he keeps his bum down, and his nose, but his front legs still straight. Huh. So, any tips?
