dog sick

what to give dog my black lab that has diarrhea the past two days.  Do not know of anything that she got into..  She does eat dandilions heads once in awhile.

any help is appreciated

She would be 80 lb female British lab

had this happen a couple of times so yes definitely get them to drink water, limit the normal food or use very little but put pumpkin or yogurt in there, they should be back to normal in a day or two

Water with electrolytes would be my first thought....
