My boyfriend always says Dudley "plods"...sorry, but it's true. Can he run and move fast -- oh heck yeah -- but always on his terms. I don't know about Murray (GREAT name by the way), but Dudley is intensely curious. He smells and checks out everything. I mean everything. Goes out...sniffs the air...smells his toys in the yard...smells the patio furniture...you get the picture. Dudley will be 3 years old in December...he's not going to grow out of it. Most of the time, it just cracks me up, unless I'm really tired (like tonight), in a hurry, etc. But...that's Duddles!
