Over the past 20 plus years all our dogs until now have been undocked or dewclawed weimaraners. Our current two are weimaraner GSP cross again undocked or dewclawed. We live near the New Forest and although we do not shoot, we walk them as though we did. The dogs will go through and over anything, miles every day over and through rough ground through gorse bushes and brambles. Touching wood, none of our dogs have suffered tail or dew claw injuries, although they have had cuts, grazes, slpinters and thorns, muscle injuries and so on. The lady who bred our dogs all except the last two did used to rough shoot, again with dogs with full tails and dewclaws and none of hers ever suffered tail or dewclaw injuries either.
i realise that this is only a limited study but it does make me wonder if docking is as necessary as it is made out to be.
