Newfoundlands do not reach full maturity until they are 3-4 years old. At 2 years old, your dog is basically at the height she will be at for the rest of her life, but she will still fill out until she is 3 or even 4 years old. The average Newfoundland weight for females can range from 100 lbs - 160 lbs, depending on the breeder, the linage of the dog, what you feed her and of course, how much exercise she gets. Newfoundlands need about 1 hour of exercise a day, swimming is the best exercise you can give her, as it is low stress on her joints. Walking on leash is great for them as well, and off leash parks are fun for them too. But never force your Newfoundland to run, if they are off leash, they will run at the pace that is comfortable for them. As for winter, she will grow her winter coat naturally. You can prepare her coat by making sure you brush your dog on a daily, or bi-daily (every 2 days) basis. Her body will adjust to the cold and grow her winter fur naturally.
