I have an Australian shepherd and live in dense woodland! I put this on my dog and didn’t get much relief after 30 days. I did notice the ticks were smaller and not bloating on her! Decided to give it a chance and gave her a second dose. The second dose did the trick. She is tick free and I appreciate not having ticks on my furniture and on me!!!

Easy to use but did not work for any of dogs.

Really not strong enough. I have tried this several times now and must conclude that it is not a good product. Does not get rid of fleas and ticks on my dogs.

I found this works just as well as any other flea/tick medication, and does not irritate my dog's skin. However, check your packaging within 30 days of order date on Amazon. I bought a 6-pack in August, and the first 3 tubes were fine. (They are packaged 3 tubes per clear plastic inner pack.) Four months later, I opened the second 3-pack, and discovered that 2 of the tubes had leaked -- badly. So, I paid for 6 but got only 4 usable doses. Because I'm well past the 30-day return window, Amazon won't help. SO, the next time I order, I'll check all the tubes as soon as the 6-pack arrives. Other that that, this is a good product.
