Sky biting diesel

Although they get on fine sky my 10 week old pup keeps nipping my older staff diesel under the neck when she does it super ate her till she calms down he just takes it as he is soft as muck also say no then give some thing to chew on that she can bite or chew am I doing the right and is it just a matter of time any advice would be great

It sounds like normal puppy play, and nothing to be worried about. Diesel will let Sky know if she goes too far - this is in fact a great way for her to learn how to play without hurting, a skill that she will need with other dogs. I would let them be, other than to take the opportunity to teach them 'enough' so that you can settle them if they get carried away playing.

She's drawn blood not deep just like scratches

It happens, especially with those razor sharp teeth she has at the moment. If we are just talking about scratches, I really wouldn't worry.

sky will learn a lot from diesel

Yes Diesel will let her know best to always keep an eye though
