I have a question about a harness. The breeder I am getting my puppy suggested that I purchase a harness and not a collar. I have been to a million websites and the sizing is all different. It keeps asking how big the puppy is around the middle. I don't know cause I don't have her yet! Also I was wondering how thick or thin it should be. I don't want it to weigh her down. She is one of the bigger pups and her mom weighs a little over 7lbs and her dad weighs 5lbs. Do these harnesses adjust much or am I going to have to buy one for puppyhood and when she grows up? It is hard to guess on these things. If anyone has any suggest where I can find a good harness that would be great. THis is the link to one of the harness I am looking at. It is the first harness pictured

We have a very long drive home and I want to have something on her so we can stop and take her potty safely. Thanks for your help... I just don't want to have to deal with shipping anything back : )
