  • Product description on box is misleading
    My order was shipped/received on a timely basis. When I opened the shipping container and pulled out the product, I initially thought the company had sent me the wrong thing. In large letters on the front of the box, it states "Quickly kills ticks" and underneath was listed the types of ticks it kills. On the next to the last line, it did state that it kills fleas and chewing lice. I went back online and reread the product description to make sure I hadn't made a mistake when I placed my order. I went ahead and applied the Sentry to my dog, and I'm happy to say that it DOES kill fleas. I have tried other more expensive products that either didn't work or had unpleasant side effects, so I'm very happy with my purchase. I would just recommend redesigning the box so that the information isn't misleading. by on 02/24/2015
  • Do not use Sentry on your dog!!
    I purchased Sentry Pro XFT from Petsmart as a replacement to the frontline product. About an hour after application my poor cockapoo began itching and scratching furiously at his back. He does not have fleas, inside the house almost all the time. We washed him immediately, but still no relief. He is so miserable. Come to find out, many, many pet owners have experienced the same thing with this product. There are online reviews everywhere with the same complaints. Sentry, you should be ashamed for continuing to put the product out there, it needs to be removed permanently! I won't touch another Sentry product with a ten foot pole. by on 08/22/2014
