Thoug I like frontline and advantage, I would tak advantage over frontline any day. Its easier to apply.

Pros: easier to apply

Cons: none

This is an amazing product. Works super fast, lasts a long time. I wont use anything else.

Pros: works fast, very effective

Cons: little pricey

Good flea control in the beginning but effectiveness wore off after useing for about four years. The tubes got to where they did not have but only a few drops in them which caused my dog to get fleas. Complained to the company and they had the vet where I purchased it at to give us a free years supply. Still had to switch to Frontline which does not kill fleas as well. Also Frontline does not repel mosquitoes. This concerns me because Bubba had to suffer through heartworm treatment. We caught them very early and she is doing fine now but I would feel better If I knew she had on something to repel the mosquitoes.

Pros: good flea control

Cons: fleas became immune

I have used Advantage on my dogs for quite a few years. It works well. A little on the expensive side, but worth it.

Pros: works well

Cons: only good for 30 days

My male cat was diagnosed after an agonizing six months with asthma. His symptoms included difficulty breathing, lethargy, and severe coughing with excess mucus.

We had used Frontline on our cats for years but found that every time we applied it to Flash, he had a severe asthma attack. Internet searches revealed that Frontline and Advantage have different active ingredients. We switched to Advantage and our guy has had no allergic reactions. It was a miracle for us to ease his suffering. Thank you, Advantage!!

Pros: Not as toxic to my asthmatic male cat

Cons: Doesn't kill ticks
