dog is 3 1/2 months old sits comes and fetches good i live more in city type setting small woods down street that i take her down and walk her off the leash to let her get used to when we go hunting i don't let her get any farther then 30 yards just started hiding wings in two feet of snow with a little bit sticking out in bushes when she gets five yards away she smells them and finds them but would rather chew them and stops listening to me didn't want to punish to bad i'm happy she found them but don't know if i should wait till i get bird launcher or just let her have one in back yard for a while don't want her to loose interest in them either first dog as an adult and learning any suggestions thank you
