As a breeder of Yorkies of color myself, I personally would not breed that dog. That is just the first problem for this little pup , what else could be hidden or lurking. I have a hard time to not lose my civil tongue when I hear about a breeder selling another breeder very poor breeding dogs. Was this pup even taken to a vet before coming to your house?
Does the breeder of the litter not even see that the eyes are different sized?
It is very obvious in that pic. That pup should have been sold on a spay/neuter contract.When breeding you want a great example of the breed, and using that pup would be starting with a poor example of health right from the start. Please do the right thing for the breed and the Parti line and give that puppy back to the breeder.
You may be attached to the pup and if that is the case, spay her and keep her as a pet, knowing that she could become blind. But would you want to pass that on to a litter of puppies knowing that one or more of them could end up blind...and then...keep going down the line until multiple partis have that in their lines... scary but think about how many potential pups could be affected. This is soo frustrating
Sorry I will get off my soap box now...
