John:
I actually did a little test in the "food/roasting" area of the house.
Anything dropped on the floor the dogs eat, it is for them...
You mentioned marbles and I am laughing my ass off here since I collect and
play marbles.
I have dishes around the house full of marbles since ya never know when a
game may start.
One of my dogs found some on the floor and of course thought it was his
snack. About two days later I was trimming my roses and here is about 4
inches of dog poop holding six marbles together...
our puppies will swallow anything!
