Find pictures of dogs you like and bring them with you to show the vet. A good vet should be able to use that info plus his own experience of what kind of cut will flatter what kind of head and give you a cut you will like. Remember too that a long show cut generally takes longer to stand and is a bit more work--factor that into your personal preferences.
Dr. Staples is great!!! We did the almost 2 hr ride from Windsor to get or females ears done around 2 mnths ago and and let me tell you it was very worth the trip. My wife and I searched online to find the crops we liked most and printed them off. Then we showed them to Dr. Staple and he helped us pick the one we thought would suit her best. He's a very nice guy. Dropped her of at 8:30am went shopping and picked her up at 3:30. Good luck with what ever choice you make.
That's great. Gotta love the foam between their ears.lol . But in all honesty I think it works a lot better then fully taping their ears up around a cup like some of the other vets do. Gingers ears stayed glued to the foam for 3 weeks. Lucky for us both ears came off a day apart from each other. Post some pics.
I brought pictures but be prepared, he might ask you something you're not ready for...can't recall the word, I think it was traggus...'do you want the traggus left' he asked...I had no idea what that was at the time but he explained that it's usually removed. It's some of the skin at the foremost part of the ear that is often cut away but sometimes left...I'd know it to point it out but not sure if that's the best way to describe it. Here's a pic of a Dobe with the traggus (sp?) still in tact...it's that extra skin and fur you see around the opening going into the ear (did I describe that right? probably not):
EDIT to add: I see you already got 'em done...alas, my post is of no help to you!
