On Saturday I met a vet in the Des Moines area, that has taken in a 12 yr old female yorkie. Her name is Chloe & I just went & met her. I will post pictures of her later.
Here is the story as I know it.
Chloe's owner has congestive heart failure & this little spunky girl was getting too much for her to handle and waking her up, so the owner wanted to put her to sleep.

The vet, told the owner, no lets see if we can find her a home.
Chloe is not very big - but she is over weight. She weighs between 7-8 lbs - she wouldn't hold still on the scale while I was there today. She probably should be more like 5 lbs or less. So she could lose some weight. I think she may have been eating bad people food
She needs a good dental or at least some Petzlife and some bully sticks to clean up her teeth.
She is a talker. I spent about 30 minutes with her at the vets office today and she was telling me all kinds of thing. She moved like she was younger than 12 yrs of age.
Her ears are not standing up all the way, but it looks like there is a lot of hair on them, and maybe at one time they were up. She has an interesting little hair cut. Basically shaved down body with kind of a lion cut on her head.
She has 2 little moles on her back. One is a little raised. She is current on her shots
I'm at work, but I will try to post pictures of her later.
It sounds like they would give her to the right home. I was considering adopting her, but the timing is just not right for me. Hoping someone else in Iowa might have a heart & home to welcome in an older girl
PM me if you want more info on Chloe
