Yes, within any breed there will be harder dogs and easier dogs. My next door neighbors own a sweet "easy" rottweiler. I had a "hard" rottie. Reading these forums the last few months, a few people have "harder" corgis. I'm delighted that Charlie is "easier".

A hard dog can become a fine pet with consistent, vigilant training. An easy dog can become a real nightmare without at least basic training skills, but really flourishes and shines with a lot of attention and training into the type of dog that "everyone" wants to own.

Just seconding Cindy's comments: training (to fit the dog's unique personality and breed), temperament, and breeding.
