This is an incredible product and we have been using it for many years on our dogs. We haven't had a flea for over 15 years. It works well on small, medium and large dogs.

What about ticks?
A shopper on Jan 13, 2018
BEST ANSWER: We are a rescue way out in the backwoods where wildlife is abundant. Lots of deer. squirrels. possums, rabbits, foxes, bats--you name it, we've probably got it. Ticks are also abundant and spread by the wildlife. K-9 Advantage II has been extremely effective against ticks, fleas and mosquitoes. Advantage works as well. It just does not repel mosquitoes. We are diligent in timing applications every 30 days.
