Ah, I don't worry how things "should" be done. My dogs listen to general commands that count in my book. They have the run all day long on my property and they stay there. They are also lucky enough to have the basement to sleep in. I'm such a nice guy
They are retreivers, bread to retrieve birds. Alive or dead, they're gonna retreive it. I'd never scold my dog for saving me a .75 shotshell!
I may be upset cause I didn't get to slaughter it after walking 2 miles, but that's what I get for hunting public grounds with stocked birds that run and not flush. Those birds take their chances too, they can run and try to outrun one of my girls or flush and hope that I miss (which is rare). Come home with your daily limit here (if you didn't follow the stock truck all day) and you had a good day no matter how they were taken.
