Yes, it is polite to ask if you are going to take photos up close. Some do not mind, others do. Just be sure to ask first.
As you found out we do not mind - asking questions, we try and help the breed and to inform as we can. If you get a yorkie magazine - The Yorkshire Terrier and/or The Yorky Club Magazine, you will be able to see many beautiful show yorkies. There is also the E Magazine for yorkies too now (on line).
I could not get away from work, so could not enter the Raleigh show. They are have the Roving one coming up in Oct. in Tenn. Just check out the web site -
Yorkshire Terrier Club of America for more information.
Thank you all so much. I love her eyes too.
