I don't understand why she thinks she can't train her dogs, particularly Diane. My friend has a beautifully trained sausage dog - sure she is a bit suborn at times and has a lot of sass, but isn't that part of the charm and the reason people love and then own sausage dogs?
I will say though that same friend taught my own dog how to do shake so maybe she's just brilliant with dogs in general
Also, imagine just outright saying you love one dog more than the other all because you're too much of a
tit to train your puppy so you hate it??
