I have tried them all...frontline, Revolution, Sentinel and still had fleas... K9 Advantix and Advantage is the only ones that I found that work...I use the Advantage in the summer for the fleas and the K9 Advantix in the winter for fleas and ticks...ticks are really bad here in Florida during the winter months...I only use them if I need too...sometimes we can go a few months without using either one but other times like right now the fleas are bad and I have them on Advantage. |
