How soon does this expire?

I have ordered this product 4 times since March 2022 and every time the boxes come expired from 2021. Refunds are issued, and I try again, but still the same: I receive expired products. I'm very disappointed that Amazon cannot get the expired products off the shelves.

How long does it take to kill fleas?

you should see a huge improvement within a couple days!!! its the only thing that isn’t prescribed that works for my boy. hope this helps!!

How soon does this expire?

I also received this product in May 2023 and the expiration date states 7/12/21.

Since when is 21lb considered a large breed? i have a german shepherd - they must think he's a giant? causes loss of credibility in the product ...

The size breaks are a bit different, but the product works fine. Guess you need to try extra large since guessing your German shepherd ways more than 55 pounds at the end of the range.
