Labs can digest anything.
No, they can’t. We were dog sitting a neighbor’s black lab. He knew they were going out of town and began his nervous eating. Unfortunately, he found some cigar butts and chewed them up. Let’s just say we should have put him in his kennel that first night. Their cream colored carpet was never the same. He had explosive runs for days. We started feeding him rice, and he was ok after a few days.
