Perhaps they didn't think they would have twins. Twins = twice the cost, twice the time. They may have had time and money for one child and the dog, but 2? Thats something they couldn't help.For me the issue is I see so many people giving up dogs as soon as they get pregnant (we are having a baby boom in SF). I think there is another thread about that. Its like, what you never saw your self getting pregnant and having kids when you got the dog?
Yes he sounds like he is placeable, but really, so he will get placed, and another dog wont... and in a few years, they will get another dog. Animals are not disposeable, and I do not actually feel that just because you decided you are going to have kids, out goes the dog. They chose a GSD, high likely to have alpha dogs in this breed, amongst other challenges ...
