Does anyone have any advice as to how I can stop my 6mo from throwing his water away. What I mean is I leave him in the backyard when I go to work. I have a covered patio with lots of shade. I leave him 2 big bowls of water, he is alone for about 5-6hrs, but when I come back the bowls are empty and on the grass. He has never done this before until just the last week. I know he hasn't been drinking all the water because when I bring him inside and fill up his bowl he drinks it all right away as if he hasn't had any water all day.
