Comparison of Advantage Spot-on and Advantage II Spot-On
Advantage and Advantage II are from Bayer, and both are effective topical treatments. In addition, both provide a month of protection against adult fleas for dogs and cats. Most of the per-owner topical treatment as it kills parasites. The topical treatment works through contact; it will kill fleas, so fleas do not need to bite your pet.
The critical difference is that Advantage II has an additional active ingredient, Pyriproxyfen, that eliminates fleas at the egg and larvae stages and helps control lice infection.
The advantage is safe to use on cats & dogs over eight weeks of age, while Advantage II is safe to use at the age of seven weeks and cats at the age of eight weeks.
It would be best to weigh your pet before administering any medicated treatment and always use the proper size.
