i have got some frontline is it ok to spray where scabs already are, how often to apply, and do you just spray on the back of leg?? Calmag is calcium and magnesium.
I hibbiscrub my guys legs to remove the scrubs then the next day put frontline on. I put in on all parts of the legs as they get them on front as well, being hairy beast. I tend to put it on every 4/5 weeks, basically when they start itching again.
