How do I stop my new border collie from nipping at my other dog?

I recently adopted a 6 month old border collie from the shelter. At first he did well with my older (8 years old) dog, but the second day he started nipping at him. How can I stop him, my older dog is starting to show his age, so I don’t want him to get hurt? I have already pointed away and told him to stay, works for a while, but he goes back to nipping. Please help.

How big will my little border collie puppy grow too?

I have an 8 week old border collie puppy she was the smallest of the litter, but not by a lot. How can i judge how big she will grow too at the moment she is tiny, only about 3/4 of the height of my other dog who is about 11 – 12″ high..

is there any sites that actually work this out or any tips on working it out?

P.S. her feet are very thin and very small.
