She is beautiful - I love the thin blazes.
We have two Berners - my 8 month old male Zurich is getting close to 90 lbs, our female Treva is about 75-80 lbs. They are incredible dogs, but as the saying goes "Berners are like potato chips - you can't have just one".
(You'll figure that one out, especially since she is a girl)
Ours were both completely housebroken by 16 weeks, it goes fast.
