Hahaha!!! My first Newf, Otis, did the same thing. I know he was snickering under his jowls at the way he made me look like an absolute fool!
How old is Bella? With the giants, as puppies, they get tired quickly and the rule of thumb is to walk a minute for each week of age until about 6 months. So a 3 month old puppy will get about a 12 minute walk - 6 minutes out, 6 minutes back. You can do it a couple of times a day, but keep in mind how quickly she is growing and how much energy that takes. Once the growth slows down a bit, they are more cooperative about walking. Also, once you go to puppy classes, they learn more about behaving and she'll get the idea from the others. Just be very gentle with her and she'll come along well!
