Since docking is now illegal in Europe, and docked dogs, even from other countries, can no longer be shown there, I think we'll see a marked decrease in docking showdogs very soon in this country. We already have so many imported, undocked poodles being shown in the U.S. that it's becoming more and more common, and therefore accepted visually. It's nothing but what people are used to seeing, and all about what constitutes, in peoples' minds, a "balanced outline". It's totally fashion over function, but when you have people buying puppies expressly to show, you feel obligated to give them the best chance at being competitive as possible, and no one wants to show up with the entry that's "different."
We have docked our own puppies' tails, and it is kind of a non-event, compared to what you expect going in (although our breed requires far from an extreme dock). We don't cut, there's no blood, no stitches, and no expressions of pain from the pups. Removing the dewclaws seems much more stressful, though the way we do it, it is also a bloodless procedure, but the pups
do cry for a couple of seconds. We do it at 3 days. As a matter of fact, I can't do dewclaws. I get light-headed, and my husband has to do it.
I would not mind at all leaving tails intact, and we're actually considering it for our next litter. Two things make it easier to do that--one is that poodle tails have been getting longer and longer over the years in the show ring, and the other is that our breed does a lot of importing and exporting of show dogs, so judges are getting more used to seeing outlines with intact tails.
I would LOVE to not remove dewclaws, but every dog I've had with intact dewclaws has had problems with them getting torn. I don't know how different it is from breed to breed, but with the dogs I've had, the dewclaws seem to barely be attached, and prone to ripping easily.
In short, in my experience, the dewclaw removal is the more invasive procedure, but I'll still be glad when tail-docking is phased out. I don't feel like it's cruel, done correctly, but I do feel like it's silly and cosmetic and unnecessary. But we do show, and showing is, in many ways, silly and cosmetic.
This is Delta, who was whelped way back in 1999, and you can see how long tails were even then...so it's not such a big leap now to simply leaving the whole thing. If she had a pom on the end of that tail instead of being totally shaved down, it would look even longer.
