Need a vest for my GSP for the upcoming grouse season.  Just the nylon type that protects her chest and under carriage.  The problem with past purchases I've made, is the deep chest of a GSP throws off all the sizing charts.  It usually fits in the middle but is tight around the front and rubs around her front legs/body area.   Any suggestions?

I tried a Cabella's XL vest that my last english springer wore and ran into the same problem that you are having.  I was wondering if Binni even needs a vest?  Everything seem to roll right off of her short hair.  Not sure.  This will be her first time out hunting.  I know my english springer pup will need one.  That hair is a nightmare.
