Rats, Yorkie was my second choice. My two cents? You've had the dog longer than you've been married. If your wife can't come to some agreement with you over the dog, I also believe you have more problems than just the dog's health. Are your family's finances so tight that taking care of your dog is an issue? What if you got just one of the cataracts removed, so the dog won't be completely blind? Is the stomach problem endangering the dog's life? If not, hold off on all the expensive tests. These are just some suggestions to put on the table with your wife. If she rejects them all, hands down, you have some questions to ask yourself about your wife.
