Flea question

Question
Can I use a couple of drops of Advantage Flea treatment for dogs over 55 pounds on a 15 pound dog?  I found a flea on my dog today and I am out of his med and can not get in till end of next week.  My neighbor gave me one of hers, but I don't want to hurt him....help!

Answer
Sincere apologies for the delay.

Though it is not recommended in a pinch you can do this.  The problem is  to be careful with administering it so as not to use too much.  If you have an eyedropper handy I would recommend emptying the packet into another container and measuring out the drops.

I hope this helps.
