Always be sure you're watching any time your Sheltie has a bag -- of anything. Tragic accidents can happen. End of spoil-sporting.

You're right, Chris! I just read about a man who tragically lost his sheltie due to him getting into a potato chip bag so maybe you mean something like that? This bag of dog food is very large and I no longer keep it on the floor. But I always appreciate any warnings! Thank you!!
