I'm not sure which is sweeter...
...the little boy who can now ride all the way to the cul de sac and back on his Rad Cat bike complete with Spider Man helmet and bell. (Bonus: He rings the bell when he reaches the top of the hill).
...or the gentle giant who watches when they leave and stands guard at the edge of the yard until they make it back home safely.
OK, so the dog is an easy third, but I still thought it was a sweet gesture on his part.
