Works great
I live in an area with a lot of ticks - I have to look my dog over every time I bring him inside. If I miss any, I’d often find them flat and dead - so it seems like it does its job!

Works!
We have a golden doodle that we take here and there to my in laws farm. He tends to catch lots of ticks but when we use k-9 advantage, he comes home tick and flea free! He doesnt care for when it comes to placing it but as soon as we are done, we let him run free and he doesn’t itch. Picture of my pup to show how long his fur typically is. We do have him grow it out some but usually it is short other than his tail that i joke is a feather duster.
