what to do to prevent ticks on my dog

Shave the dog

I`ve used frontline on my rottweiler and it doesn`t work. flea collars are useless on him got some new stuff and it doesn`t work either.
my yard is an acre that used to be a prarie. think I`ll try the sevin dust next time. not supposed to do anything for 36 days w/ this new stuff that already don`t work. SUCKS TO SEE HIM SCRATCHING ALL THE TIME!:thumbdow:
