Ark Naturals - Neem Protect Spray Pet Care, 8 fl oz liquid

This spray should not be classified the way it is on Amazon. It is for PETS, not people.

It definitely helps repel the ticks.
I took my 3 dogs out here in NJ for a walk down a road 2 nights ago, and only one had the Neem spray on (from a previous training session).

Of the three, she was the only dog that had zero ticks when we got home.

My dogs are short coated with white hair so it is fairly easy to visualize the ticks.

It does come off once they go in a pool or water, so you do need to reaply if going out to a field or roadside walk..
