It's a little hard to see ... the photo is out of focus.
I have never removed one, so I can't say, but I will check a couple of breeders I know that use them and see what they say.
No one is perfect 100% of the time, I am sure the breeder that did it for you meant well, but I wish they had told you how to remove it after the show.
You did the right thing in separating the chins, but you still have to watch out for her scratching or pawing at that area with her feet/hands of her own. Make sure you do not put the chins back together until the wound is completely healed ... no redness or raw skin at all ... OR the
mate will try to heal her, this
could end up with part or all of the ear being chewed away. I would use a good triple antibiotic ointment like Neosporin. This will promote healing and keep the open wound soft and from becoming hard and itching as it heals.
I'll send out a few e-mails and get back to you. If someone else know ... please jump in and say so ... this tag needs to come off a.s.a.p. ... there is already damage to the ear and it will no longer set in properly and will only get worse.
