Do your homework on the breeder. You will be glad you did. My wife and I have a 3 month old female Rott that we found abandoned in an ally when she was about 3 weeks old. She has turned into a happy go lucky pup. We are fortunate that she is a good dog, although she plays quite rough for a 3 month old.
Be prepared for this dog to EAT eek!
Our pup is about 35 lbs right now at 3 1/2 months. The vet said she is going to be about 100 lbs.
Great Dogs, Good Luck
