I fostered this girl for three months. She is a blind and deaf Great Dane named Pumpkin. She had a sibling that was also deaf. They are both the result of
breeding a Harlequin to a Harlequin, it can create a condition called Fatal White.
I don't agree with the euthanasia of deaf pups but I can also understand the point of view that sometimes it's better for the well being of the dog. Both Pumpkin and her brother ended up in horrendous situations because of their disabilities. Her brother went to a good home but managed to pull the leash out of his owners hand and did not see the visual cues or feel the vibration cues that where being given to him as he ran into the street he was hit and killed.
Pumpkin ended up living on a back porch for the first two years of her life, skinny and ignored because her owner was not experienced enough to train her or care for her needs properly. She has since moved on to a fantastic home with a family that has previously cared for a blind and deaf Dane.
If every deaf puppy could be guaranteed a home where they would be safe and could be trained well and managed I'm all for saving every one of them, but there are so many deaf dogs being born that finding them the proper home is hard to do.
