Happy chaser

My mom's dog Aran, running after a frisbee. He's rather old (ten) and is starting to have problems with his legs, but definitely loves his frisbee, even more then balls and sticks. When he was young, he kept running till he couldn't breathe and then refused to return the toy. Nowdays we only throw it a couple times, since he tends to only remember his sore legs once the running is done.
