Works Great

Easy to apply & haven’t had any issues with fleas or ticks. It also doesn’t seem to irritate my dog at all.

Flea Treatment

Just made the switch to this after using other brands. I'm using multiple levels of treatment on my pets and yard. Hopefully this switch will do the trick.

Waste of money!

Does not work at all! I tried it more than once and horrible results each time. Save your money and buy something else.
