Who says old dogs can't learn new tricks?

So my oldest dog Katy is learning a new trick. She is finally learning to roll over! Well she has part of it down. She rolls on her side but I have to push her all the way over. Now Jake on the other hand grumbles and moans every time we've( my family and I) tried to teach him to roll over so I;m thinking that is not going to happen for him. But Katy has potential. So I'll keep you updated on her progress. She's so smart its scary sometimes.
