Based on the description, it's the correct part. Priced at $10 cheaper than I found them on Amazon, it's a deal, but not like they're so cheap it's not believable. Looking at their feedback, it seems like they're an overstock seller.
The sheep generally do not like the sheepdog. He looks a lot like the wolf. They would prefer the sheepdog cash in his fangs, spray paint himself white, and go, “Baa.”
Until the wolf shows up. Then the entire flock tries desperately to hide behind one lonely sheepdog.
