My sister really wants to get a dog once they move from Hawaii (very soon!). She was looking into retired greyhounds but has heard conflicting information on how they are as family dogs. I am assuming that the rescue/owner would be able to give her information about each specific dog? She has an 18 month year old (who looooooooooves dogs) & is planning on having another baby, so she just really wanted to make sure a retired greyhound would be a good choice! What do you guys think?
