Beaucerons are big working dogs ranging from 70 to 110 lbs. in weight. They enjoy their exercise, and are extremely athletic. If you want a Beauceron and do not have much room outdoors, or live in an apartment, a smaller female is recommended.
If you are not an experienced trainer, and are not going to use the dog in one of the hard working sports (Ring, Schutzhund, Protection) stay away from high drive males. You are asking for trouble with extremely dominant puppies, unless you know what you are doing. Dominant male puppies which can be handled as pups, become dominant male dogs which cannot be handled as adults. Without a working outlet, dominant large males cause major problems, especially if you think you are going to use the dog in a protection role.
Think before you buy!
