These were two perfectly healthy dogs. One of the in-laws heard of this and went to the humane society to reclaim these dogs. Unfortunately, because the one was around 8, they immediately put it down because they didnt think anyone would adopt such a dog considering they had so many younger ones available.
So, yes, a dog can look well-taken care of, but some people just don't want to be bothered after a while, even though they may have had good intentions in the beginning when acquiring the pet. No excuse, though.
