Yes I totally understand trimming of parts which are sticking out of somewhere, but to take of the full length of the hair growing from chis ears, that's what I don't really get and that's what they do there.
It makes them look like puppy's again

Well I am no expert, but I have never seen this here in the ring.
Yes cleaning ears, eyes, teeth, cutting nails, clearing pads, cleaning the bottoms and so on - that's fine and we do that all the time anyway, show or no show.
Thanks for your opinions
