Well, I don't have a large dog, I have a small one that I get very concerned with when something like strange poop happens. It didn't take a fine tooth comb to see that something wasn't right. She had not eaten anything strange, nor did she act strange. She IS fine now, but I just wondered if anyone else could give me some insight as to what it could have possibly been. That's all.
I appreciate the helpful comments...

Have a good week!
