Just an observation...This is not the first dog I've had that does this. I cook with natural charcoal outside in an old fashioned Weber grill. The charcoal sort of sparks and drops out little shards, which eventually cool. My dog will eat the charcoal out of the little catch pan under the grill if I let him. I usually clean it up but it is a hassle.
Do many of you have this happen? I could obviously go with the briquettes or gas and avoid this, but I won't do that. I guess I will have to condition him to avoid it (+P) or just clean up every time. What a drag.
I am sure he has eaten quite a bit of it over time.
