I agree with all the others, just wanted to add also, that the whitish blue eyes may be how a dog's eyes reflect the flash - they don't get "red eye" like we do.
(That's not to say that the dog doesn't have cataracts, most older dogs do.)

OMG! It looks exactly like him. Super job!

Oh I think you did a gorgeous job! Sorry to hear this may be your last portrait. I've heard the same thing from people who do human portraits.

Great job. I think the "cataracts" are just light refraction from the camera flash. But you did a lovely job.

You shouldn't worry everything I have seen you post is exquisite

I think all the animal portraits I have seen your pictures of have been wonderful ~ this one included! I do think customers could at least let you know that they are pleased with the results and save you a lot of worry! Great work!

How could you be having doubts, this is one beautiful and realistic quilt, great job!

You did a great job! How sweet!

Shame on them for not letting you know how they feel about the job you did. It is awesome!
