blind dogs?

I have kept cat pups that were directional,or partial hearing and placed them with experienced dog handlers to use for blood trailing deer
and they worked out fine. However if buy 10 weeks and they are totally blind or deaf I would have them put down. My reason is this.
He's a pup now and can't hardly do no harm. When he gets older and someone walks up on him and startles him he will bite whoever out of
a defensive reflex. The probability is real high that this sort of thing will happen. As that pup gets just a little bit older he will start getting
frustrated at times and the owner will too. As far as being intelligent , you are right , their other senses are developing stronger to
compensate for their deafness or blindness. It's one thing to have a dog go blind or deaf in their later years but it's entirely different when their born that way. Hey, just something to think about. If someone decides to keep him it will be an uphill battle. Like I said, He's a pup
now but as he grows he and owner will get very frustrated. He will require a lot more attention and socializing than his litter mates. I have
only had a few deaf pups born on our place, I've never had any blind pups. Anything's possible so good luck with what ever you decide.
