That is abhorrent!
"The kids have moved out so now no-one loves her" ???
If you didn't want a chihuahua for yourself why the hell did you get one?! If the kids wanted oneaand you did'nt you should have made them wait to get one when they get their own home! If she wanted to make an effort she could, the love and devotion of one person is plenty enough for a chihuahua!
argh it makes me angry
