Hi, just had the same problem diarrhoea and eating grass to be sick with my 2 year old - started off with eating the puppy food - starved for nearly 2 days - gave her scrambled egg - took her to vet as even taking up the water she was drinking - antibiotic as had temp. and Koalin - getting better - not so runny - but plenty of washing lol. She is still leaking - so keeping an eye on her - still drinking and eating - but not puppy food, feeding them seperate. I worry about my dogs more than the kids.
