Bests & Worsts Reviews from Amazon

The authentic product is very good, but I was one of the customers who had their order filled by a third-party vendor in China who is producing counterfeit Dasuquin. While I was still unawares, I noticed that my 80 lb lab mix, who usually loves his food, didn't want to eat his breakfast. He began eating grass daily and vomiting. I reordered from 1800Petmeds and received an authentic bottle. But now I feel as if I need to front load with a double dose again for 6 weeks since he's been off the real thing for at least a month--or maybe longer! I love Amazon, but they need tighter quality control. *The bottle on the right is the fake Dasuquin. It's missing the "Made in America" logo.
