It is a challenge, so I enlist help holding the dog, then I part the hair with a fine comb and do my best to pour the Frontline in a single spot. No rubbing. Let it dry.
Your little girl is very small, so she doesn't need the entire contents of a single application. I buy the smallest ones available and I split them between my 2 boys who are 7 and 8 pounds.
