Hi There
Congrats on your new Springer Pup, welcome to a wonderful world

Nipping is common behavior, so what I do with all my springer pups when they nip is let out a very loud EEIIYYEEEEEEEE and stop whatever fun they were having ege playing etc, and I get up an walk away. Soon they associate that behavior with the end of attention and a Springer hates that.

Here is some Springer Puppy info and General Springer Stuff
