My puppy Riley is almost 6 months. I didn't get him until he was around 4 months. Just recently we have started having some problems with him tipping his water bowl over. Just about every time I fill it he sticks a paw in it and dumps the whole thing! There is nowhere in my house without carpet, and if he continues doing this, the carpet will be ruined. I have tried telling him NO in a firm voice, but it doesn't seem to do any good. He will look sad for about a minute and then be on his way. Does anybody have any idea what I can do? He obviously has to have water available!
