Frontline Top Spot for Dogs 89-132 lbs, Red, 3 Pack (1010181)
Frontline Top Spot for Dogs 89-132 lbs, 3 Month (Red) provides up to four weeks of protection against ticks and fleas. The fipronil in Top Spot collects in the oils of the skin and hair follicles, and continues to be released onto the skin and coat, resulting in long-lasting activity. Because it's waterproof, your pet won't lose the protection offered by Frontline pet medications.

- Waterproof--effective after swimming or shampooing
- Breaks the flea lifecycle to prevent further infestations
- Manufacturer information and usage
Works for 4 weeks
I chose Frontline over other products because I'd heard good things about it and because it's waterproof and my dogs all love to swim at the beach near my home. What I've learned is that while it does continue to work all month no matter what, it seems less effective at the end of the month if my dogs swim daily and get frequent baths (to wash the saltwater out of their coat mostly).
