Unfortunately I am already struggling to not get him to pick all sorts of rubbish (stones, leaves, the horse poo that the endurance riders at the weekend kindly left on my drive way and the road…), so encouraging finding his food is not on my agenda at the moment. He gets his exercise and we do a lot of short bursts of training. Maybe a toy with "hidden food" is a better idea, as I can take it away at the end of "thinking" time. I'll have a look what's around.
Just got back from a 15minute walk/bounce about and he is flat out on his cushion! So I can make my cheese! Feels like having a baby again in the house - baby sleeps, so you have an hour to get on with the proper jobs!
