Natural Flea Control and Tick Remedy. Official TripleSure Site. Flea and Tick
this is what I use and it works great he has had no ticks or fleas since I used it you spray it on them and rub it around into there fur you need to spray it about every three days depending on the season I have been using it since summer it is safe and you can get 2 sixteen ounce bottles for 39.95 and they last a long time cause you don't need to spray much on a Yorkie
I reccomend Triple Sure it works great

and is very safe just go to the website and read about it and all the good things people say about it
