Q. I have a puppy that is 10 weeks old, weighs 9 pounds and has lice. She is miserable. What type of shampoo or other products can I use on a puppy.

A. First, make sure the diagnosis of lice is accurate as this is not a very common parasite for puppies. Make sure she has been examined by a veterinarian. You have to be very careful with insecticides on a puppy of this age. Frontline is a topical flea and tick medication that has also been shown to be effective against lice. It should be safe for your young puppy.
