I have a new Labrador Retriever puppy, and she is 16 weeks old.(DOB-March 11,02) Is she old enough for a flea collar or that new shot. She stays inside mostly, but outside to potty and we go to parks where there are other dogs.
It depends on the type of flea collar you buy. Some collars are only safe on 6 mo olds. Try advantage or frontline. They work better anyway. Have fun. vetcare
