I think I read that you had also asked for help with an ad. How is this for an example to get the ball rolling? I am sure you can get more ideas too.
Already house-trained! One year old CKC registered
Yorkshire Terrier. Rich colors, sweet face! This little beauty needs a good home where she can be the center of attention. I hate to part with her, but she does not get along with other female dogs or small children, both of which I have. She is otherwise loving and well-behaved. Going to a home where she can be the "only child" is a must. I am willing to sacrifice much of my original investment to find the right family that Emma deserves. Spayed, vet checked and current on vaccinations. Rehoming fee: $600 (or whatever you decide)
Maybe you could personalize it with something positive you have noted about her personality. The more I think about it the more I think you can advertise her in a positive light. For an older couple looking for an "only child," Emma might be just the ticket! She spruced up pretty nice and maybe with her ears shaved on the top half, they might start perking up. She does have some nice rich coloring. The appearance is not all important but that is what draws our attention in the first place. After that if they get to spend time with her and she has typical yorkie loving traits, she will sell herself.
Good luck! Now I will leave you alone.
I just thought I needed to at least try to provide some input to your requests.
