My vet doesn't use the mismate shot EVER. If we do a medical abortion it's similar to treating pyo medically. I can't remember exactly what the differences are, but I know last time we did it the bitch was hospitalized for a week and it a ROUGH on her. That's YOUR choice, not the choice of everyone else. I would totally take being deaf blind over death ANY day. I know a lot of people that are deaf, blind, or BOTH. And they get along just fine. A dog should be able to get along ever better than a human, considering their main sense is SMELL. Smell to a dog is like sight to a human. It's sad how someone can be so intolerable of defects.
