Nikon's basically a year old now, he had his hips and elbows prelim'd and they were fine (I will do the a-stamp in a few months when I have the $$$). He's in good condition, maybe even a tad underweight at the moment (just got back from 2 week vacay where he was go go go and now all rib-y no matter how much I fed him). DH jogs every day and sometimes he likes to take a dog. I let him take Nikon today and he said Nikon was fine and he wasn't hardly pooped when they got back. Would it be OK for Nikon to jog 2-3 miles once or twice a week?
