She's really cute. Her eyes look kinda funky to me though. Sort of googly if that makes sense! But she's still a doll and I'm sure it's her age. They should strengthen and be more 'forward' looking as she grows, I would think. She doesn't look hydrocephalic to me, but be sure and palpate her molera and hopefully it's not a big huge one. Also, check her vision, those eyes have me a little 'bugged'!
ETA: I may be focused on her eyes because of all the problems I had with Brody's and his episode of blindness/detached retinas. It makes me super sensitive to their little eyes and vision.
I do think she's darling.
If she were mine, I'd have her evaluated at the vet immediately after getting her with a contingency clause with her breeder that if something is found wrong with her, you get a full refund or the breeder pays for her problems. Remember, these itty bitties come with a price and I'm not talking "cash" price. Sometimes they are so micro tiny because they have health problems. We are all in love with Jade and how itty bitty she is, and T is lucky she is a healthy Chi! But so many other tiny ones aren't so lucky and they are small because of liver problems, brain problems, intestinal malabsorption problems, chronic hypoglycemia, etc. I would definitely want a clean bill of health and would probably go on and do a bile acid test just to make sure that she doesn't have a liver shunt.
Forewarned is forearmed and I want you to go into this with your eyes open. Hope I didn't offend.
Do you have a current weight on her? She looks soooooooooooooo tiny!!!
