Well here in hot humid Florida we definately have a flea problem...I hate those topical flea thingys that you put on them, they all make their coats greasy, and I am not happy with them...My vet does not like Avantage or the plus one. He says they are not working like they used too, so he gave me Confortis to try with the boys. I gave it to them last night with dinner, and so far they have been fine, I know it doesn't help with Ticks, so I use the tic collar, I have used it before, because I never needed the flea stuff before about 6mos ago. I have my property sprayed, and my house is sprayed too. My guys are only walked on our property, and I had no problems, but I guess that is over with now. Any one else using this Confortis??...And oh by the way, when I told the vet that it was cheaper by $20.00 on line, they told me to make a copy of the page from the computer and they would meet the price...I paid $73.00 for a six mos supply, which will only last me 3 mos since I have to give it to both dogs. I had them groomed on Sat. and the groomer found fleas on Oliver and Renny, not a lot, but they were there, and Renny had 4 ticks!!!...I called my exterminator, and he is coming on Friday to check out the house and lawn etc...Ugh I am so allergic to fleas, had an infestation once yrs ago, and don't want to go thru that ever again...Anyway, has anyone been using this Confortis?..Just wanted to know if it is as good as they say it is, thanks, Cheryl
