Shepards are "bred" to herd/watch guard... never know one to be a retriever... No idea if it can be done. Because of their breeding their bite is strong so your concern is very valid... You can't beat a lab for companionship as you now have with your goldy, they ARE bred to hunt/retrieve. (I had a goldy/lab mix...great dog but not a hunter, just a friend). Labs have a soft mouth, patient, loyal, friendly, SMART, obedient..... you can't go wriong with a lab, just pick your color and go!
