tye and zac go 4 or 5 times aday, brandi 2 times and annie once but they all eat the same amount,all dogs are different just like people,some the food comes out the other end a lot quicker and more often than the others,i would say its nothing to worry about aslong as the dog hasnt got an upset tummy. also mine have eaten chocolate loads of times and never been ill i think it must take a lot of it to make them ill.
