Hard mouth can often be broken, or managed. Depends on the dogs, I suppose. Friend and I hunted over 2+ pairs of labs (2 guns, 4 labs). Probably half the birds were brought to hand as a group activity - but not mashed.

Only bird that got torn up.....one shot, 2 birds....wasn't really. I'd cut it in half with a load of #2s. Mistakenly chambered without looking during a hot shooting stretch. Carried it for coyotes and such.
