I'm concerned because my package was opened all the way with a plastic label saying scan this for authenticity, origins, etc. I tried scanning and received an error message. The meds inside appear to be sealed but do you want medication that has been opened. Makes you doubt the chain of custody for this item.

5.0 out of 5 stars It works!
Reviewed in the United States on May 2, 2024
Size: 6 CountVerified Purchase
My dog has had fleas a few times. When she has had fleas I get this stuff. After using this and also doing lots of laundry and vacuuming, the fleas were gone within two weeks. Once my dog went to a friend's house that had a ton of fleas. When she came home, she picked up a flea or two but they were all dead by the next day so I know this stuff works.

I had hoped this would work so I could save the trip to the vet and a little money, big mistake!
This did absolutely NOTHING FOR FLEAS. Maybe if you are buying it for ticks you might have some luck?
Bottom line is it's not worth the time and MONEY ended up spending more in the long run.
I'd stick with something from a vet.
I have used Bravecto and Simparica Trio, and they have always worked. Unfortunately this was to good to be true.
