We have a Collie Rough adult and Sheltie puppy . For 2 years we have used this for tic prevention with Detox powder the essential oil collar and searching the body for tics regularly . Be diligent The puppy had 2 tics which I found on her head on seperate times after not using this product for 2-3 days. One tic was a bit shriveled the other small and active . They have never had fleas. I would use the Detox powder ( excellent ingredients) after a tic bite or recommend with a flea problem . I also recommend contacting greenpet for advice as I have been helped by herbalists through email.
