Bests & Worsts Reviews from Amazon

The Seresto collar dose clears all flea from my dog We have used it over a year, all things seemed to be all fine: no flea But suddenly, the allergic jumps in after some fur from my dog's neck was removed for taking blood sample Therefore, while normally the thick fur of my corgi would stop the collar from direct contact with his skin The seresto collar is suddenly given the chance of touching his skin directly, after the shaving today Thereafter, my dog suddenly just keep scratching his neck so hard, even his neck skin is all getting red and even fur has come off ..... Afterwards, I removed the seresto Then his allergies just seems started to go away .... That makes me truly believe that the collar can actually cause allergic to dogs... especially when the collar touches the skin directly but there is just no such warning could be found on the instruction Indeed, the manufacturer ... just keep claiming SAFE SAFE SAFE while that might not be the truth all the time
