I have been working with a young dog and lets say his drive is not up to par. He gets in a hurry to do nothing. But for the last two days I have been doing a few water retrieves before land work and his drive is wide open. Now today I started land work and it was the same slow go dog, so I went to the water and we run a few short marks then returned to the land work and he was wide open again. Can anyone make me understand why the water seems to turn him on like a switch. Dogs have a funny way of seeing things and this is one of those times.
