I watch Maggie's consumption very close, due to Texas heat. She is one busy little girl. Her bowl holds two cups. She drinks 3/4 of the bowl daily. Each morning, I wash the bowl, and we start over. However, she drinks out of the big dogs pan, the koi pond, water hose, sprinkler, my glass, puddles, ice cubes. Good thing she can't reach the toilet. No wonder she PP's a pint at a time. Whew I would too.
