we dont have those brands over here in the uk (that i know of) we have spot on and front line. we use front line on our other dogs but they are much bigger and hardier breeds whereas millie has very sensitive skin (as most yorkies do) we groom her everyday with a flea comb to get anything out before it has time to get worse and try not to mix our dogs with others at this time of year so as not to spread/catch fleas so a flea collar is just a precaution really, she would only wear it for about 1-3 weeks x
