I just took Nero down to our local lake for a good swim. When I don't have much time for a walk I like taking Nero there and throw his ball for half an hour and let him go for a swim, which he so loves.
I threw his ball a little on the grassy bit to warm him up before chasing him into the freezing cold water, although this isn't so much fun apparently. After a while I realised that he had started to gently guiding me towards the water by not dropping the ball at my feet but at a a meter or two distance – edging his way towards the water.
When he felt he had me follow him he wouldn't drop the ball anymore at all but carry it in his mouth while slowly walking towards the water. Very slowly... so someone as pathetic as me on my two feet can follow He would frequently check with a quick look over the shoulder that I still follow him. When we reached the spot where he usually jumps in he invited me to throw his ball by dropping it at my feet, sitting down and wagging his tail.
How could resist such a look?
