Had a training jog with my best friend with four paws. We have had Jake for thirteen years. He has walking with me many many miles. He has had a leash on him since he was a puppy. Now the is a senior dog, all this walking has been good for us both. He is getting up there. He would be 82 in human years. He loves a walk. He gets so excited, you would think he was a puppy. I am asking a lot of him now to jog with me, he does is best. Still wants to be lead dog. He even get to lick the protein treat after I finished it.
