Ordered the special two boxes from the manufacturer and used it sparingly on two small Cavaliers. Just opened the second box and low and behold worm casings flew out when I picked up the scoop. Sealed it back up and called the manufacturer and was told it was over 90 days so no warranty. Told them I fed smaller amount and that was the reason for the time frame. Was told I should have frozen the second box, I told the customer service rep that wasn’t on the box as an instruction ,and she said to freeze it now that would kill the worms and we could use it! Just what a dog owner wants to do feed their dogs a supplement with frozen worms. When asked if that was all they would do she said yes sorry, we can’t help you. Won’t be a customer any longer, so watch out for the worms.
