My 15 week old female Newfie seems to be pretty small- she's about 26lbs. Her parents weren't very large and i'm noticing some labradors are catching up to her. Yes- I know females average 100-120 and males average 120-150, and that newfs take about 2 years to finish growing. She's on a good healthy diet. I was wondering from anyone who has owned a newfie before, how large their dog was at 15 weeks?
Thanks

One thing to note, large breeds do not reach full maturity til on average 3 years. Small breeds reach full maturity around 2 years.
Growth rates are not predictable as some will grow in spurts while others grow continuously throughout their maturing stages.
My Mal/Wolf - Husky/Shep mixes were all just over 20lbs at 13 weeks. In both litters, even the runts grew to well over 100lbs with a couple reaching 170 like their father. So at this point I would not try to determine how large he will be based on what you are seeing now since there is no way to predict.
