Because some people are complete jerks. The before and after pictures were very touching, though. A few of them looked on the brink of death and now look so vibrant and happy! So on the opposite side of your post, thank goodness for people that take these guys in and rehabilitate them!
Did you see the picture at the end of the page? Armella. Poor thing. Her condition before looked so bad. She looks great now, Thank God, but really these are the dogs that we now know about what about all the others we don't know about. These previous owners should be going through the same fate!
