Something changed, it use to work, not anymore, my dog gets covered in fleas

The last thre times I've ordered this, it does not work anymore, my dog is covered in flea bites. Refund my money and give me a suggestion of what REALLY works.

Doesn’t work

This doesn’t work at all for my dog. Ticks still attach to her constantly and the medication doesn’t do its job. Would give zero stars if I could.

My dog is still scratching and biting and I never saw one dead flea, only living ones. Sentry always worked before, but now nothing. My vet said that spot treatments, especially Sentry and Frontline are not working, only oral meds.

This used to work so well. But this year is the worst. I don’t know if they changed the ingredients but it didn’t work for our dogs. We would see ticks falling off of them and we would spend a lot of time picking ticks off too. Today they went to the vet. The duds had so many ticks and I was embarrassed. We had to shave our dogs and when we got home, we still found more ticks on them! Don’t buy it! Our dogs are being treated with Lyme and another disease caused by ticks.

Unfortunately, this product did not work for us. I have 4 large dogs and all.od them were treated with this product at the same time. The first month it seemed to quit working about half way through the month. The second month it didn't seem to help at all.

Sentry Flea & Tick

Have never had one flea or tick while using this and I generally only use half the amount because I don’t really like using any of this stuff

A topical Flea & Tick Treatment that works.

I have been using this protection against fleas and ticks on my 7 dogs for years. It works very well.
