My mother and I will be moving to an apartment soon (basically a house divided into 2 apartments) - there will be no fenced in yard, though we can take the dogs to local parks to exercise. We started talking and it seems that it would be very difficult to raise either of the two breeds I was considering next (Doberman or Rottweiler) regarding the energy level/exercise needs, especially when balancing with class (if it's next fall, it won't be so bad, but spring of 2013 I have to do 40hr. non-paid internships). So, we began looking for breeds that are ok with lots of mental stimulation, but not quite as much physical exercise. It would also need to be able to handle the ridiculous play antics of a Boxer, obviously. As far as what I would want to do with him, I would LOVE to try rally, obedience, and agility (obviously depending on the individual dog's personality/abilities). Size does not matter as the apartments have no size or weight restrictions. So far, I have zeroed in on Papillons, Cavalier King Charles Spaniels, & Shelties (a lady from my 4-H club has shelties that boss her GSD around).
