Jim is the most wonderful dog i have ever known. I am sure he knows commands that i don't know he knows. Friends say he speaks "Human." He just turned 11 and he is still a Frisbee fanatic. My whole family now refers to a frisbee as "the F word" so as to avoid exciting him. As much as l love puppies, this boy is my joy and has been from day I picked him up at age 9 1/2.
