[Lil Sis]

To be honest I am a little worried. Shih tuz can have genes that would cause the pups to be too big for a Yorkie.

I have a shih tuz that is 26 lbs. his sister was 8 lbs. if the pups run big this could be very bad for your girl..you would have to do c section to save her life. I would have done the spay...that's just me.

I wish you the best and pray all goes well
