So, I fed Echo dinner this evening, after he'd been inside with me all afternoon. Immediately after, he spits something hard onto the floor in front of his bowl. I went over and picked it up, and it was a pebble! About the size of a grain of kibble. There was nothing in or around his bowl prior to feeding him, and it was a brand new bag so I scooped directly from the bag. What the heck? I checked his teeth, no damage or anything. Anyone else ever experience anything like this? I'm still hoping it came from somewhere else, but can't for the life of me figure out where. I'll be calling their customer service line first thing in the morning tomorrow....
