I took in a dog 7 months ago (a 1yr old chihuahua/collie mix) who was being abused. She was very skiddish and had not been trained at all by her previous owners. Since bringing her home, she gets along extremely well with my other two dogs and my cat and her skiddishness is almost completely gone. My problem with her is her house training.. in the time we've had her, she's gotten extremely better considering she wasn't housebroken at all. She goes to the bathroom outside when we take her out. However, I don't think she understands that she's supposed to let us know when she has to go out.. it seems as though she just waits for when the other dogs have to go out, and if they don't have to before she can't hold it any longer than she just goes in the house. Whenever she does have an accident inside, she runs in her cage immediately after which leads me to believe that she understands it's wrong to do. I am not sure how to train her into letting us know when she has to go outside. I'm at a complete loss as to what to do.. Any tips would be appreciated!
