Just about any open reed predator call can be used very easy as a pup in distress. Just look for some with a thinner reed or replaceable reeds so you can change out as needed. The point blank calls Lil' Pup is designed as a Pup in distress call, and I've used it in the past, but to be honest, in the last few years my hand calls only get used when my Foxpro Fury dies after 20 stands.
