sallyandtex Posted November 1, 2011 Share Posted November 1, 2011 Hi there, Used comfortis last 6 months OK. Gave Sally dose (enough for 27Kg she is only 20kg) 2 weeks ago, and I have just seen a flea! She has been scratching like mad lately, but I thought it was her "spring skin" she gets each year. Anyone had reduced efficacy with this product? Thanks :D Link to comment Share on other sites More sharing options...
