I adopted an older dog and he was badly infested. Got this collar and put on him right away. In couple of days, most fleas and ticks gone. .

Easy to use and quick results

quite effective in controlling ticks.

tried for our one dog and it showed the result. so recently bought the collar for all our four dogs.

Was skeptical previously for using a collar in place of spot-on. However, I m happy after using the product.
