Many people know when they adopt their dog whether or not they will be athletic, largely based on their breed type, size, and overall build. Others find out when they come home and find their dog on the other side of the gate, smiling back at them. Whatever the case may be, having an athletic dog likely means you'll need to find consistent ways to tire them out and enrich their lives in a way that takes advantage of their sporting nature. Better yet, they may also act as motivation to get you up, out, and moving, so don't hold back, as you never know when introducing something new could lead to you discovering the next Air Bud, celebrity status or not.
While not all of these activities may work for your dog, making an effort to capitalize on their athletic abilities can prove to be more beneficial than just tiring them out. Agility training alone can provide significant improvements in their behavior, their reliability off-leash, their overall health and happiness, your bond and communication, and also provide numerous hours of fun. So the more you try and achieve, the more you can enjoy a deeper, more dynamic relationship with your dog, which is likely why you got one in the first place. If nothing else, you'll at least have a heck of a trick to show off as a host!
