I noticed the Frontline Plus starts with 11-22 lbs. I have a Maltese that weighs 4 lbs. Is this safe for her or should I go with the regular Frontline which says up to 22 lbs.?
As far as I know, Frontline Plus has not been approved for dogs under 11 lbs. Don't quote me, I could be wrong but either way I would use the Fontline which says up to 22 lbs. vetcare
