Is it safe to use frontline and a flea collar?

Use the preventic collar. Ive had good success. I used the frontline type products.....they do kill ticks after they bite your animal. Both my dogs still ended up testing positive for lyme disease while using that chemical stuff......so I did not see the point. Besides.....ask yourself this.....would you put that stuff on your own skin and let it soak in? I wouldnt. I try not to poison myself....and frankly....my dogs mean too much to me.
