Hi there I have bred Rotties for a number of years and would never sell a male dog (Rottie or Berner) to a home where there is already a male Rottie. Although occasionally male Rotties will run together it is by no means certain and will depend entirely on the temperaments of the two dogs and the skill of the owners. To achieve equilibrium can take a good deal of experience and management on your part and at the end of the day if it doesn't work out you will be faced with the prospect of keeping the two boys separate with all that entails.
My advice would be to get yourself a nice girl puppy as the Rottie will no doubt love his new girlfriend! Marion Brown Teversal Bernese Mountain Dogs South Africa Dogs Never Lie About Love (Jeffrey Masson)
