With the recent post about PRA in greyhounds it is worth noting that Res is included in this genetic trait. We knew it when we adopted him and it is part of why he joined the pack. We really did not expect him to be an only dog as fast as he was.
My biggest fear for him is the stairs as he progressively looses his vision. But, this is one of the most level headed articles I have read. So many articles on PRA never have suggestions. this one does.
