Q. We live in portugal. Our dogs have Scalibor collars and Advantix on, but still FLEAS! Can we add Comfortis?
A. No don't add in any other medications. The scalibor or advantix is enough. You need to ensure that you are applying the product correctly to ALL of your pets and that product is in date, for the correct size of dog and applied at the correct times. For a bad infestation it can take a couple of months to clear the problem. You should also treat your home with a good quality household spray recommended by your vet. Products will not stop fleas jumping onto your pet but will kill them within a short space of time of the flea biting or coming into contact with the skin
