A few years ago, I got a dog from the animal shelter as a puppy. I didn't really do much puppy testing, I just kind of went in there and choose the one I fell in love with. Unusual little dog, has a limp and an underbite, has the strangest habits(like taking a bite of food out of her food bowl, taking it to the other room, eating that little bite, then going back for more), but I love her. However, even now, years later, I have some problems when it comes to training her.

First off, she is very aloof, she HATES treats and toys. I've tried so many different kinds of treats, and each time, she just spits them out. I've tried using her food as a treat, even that she spits out and just stares at. She is impossible to train with anything but praise, since nothing interests her. Because of this, it takes a loooong time to teach her anything new, cause she can't really be lured into doing what I want her to. And as for not liking toys, that causes problems, cause all she does when in the house is lie there, bored. I take her for daily walks, I let her outside to romp and play with my other dogs, but inside, she practically sulks.

Another thing, she is impossible to potty train. She never goes in the house or the kennel, but she also never goes when she's outside. When she does, she's always sneaky about it, as though she's afraid someone will see. I never thought dogs could be modest like that O.o And no matter how long you sit outside with her, she still won't go. I've tried every thing trainers have told me, nothing works. I'm to the point where I just let her outside unsupervised to do her business, and let her back in half an hour later.

Also, thinking maybe she would be happier just living outside, I've tried letting her live out in our dog pen, where she has lots of room, can do whatever she wants, and can be with the other dogs, and just bring her inside for a short time during the day. She doesn't like that either, she digs out of the fence in a matter of an hour and is back at my door step.

I have never dealt with a dog as strange as her. Do I just have an impossible dog, or am I doing something wrong in caring for her?
