Long post ahead. I've been looking for a small adult dog and finally think I've found one. I'll be getting her later this week. She's a 7 year old small dog that had been bred, but well taken care of, not a puppy mill dog. This dog is not leash trained, not greatly house trained, and not crate trained. I don't have a fenced yard, although I do have a yard. I really want this dog, but are these challenges unachievable? I don't think I can train all three at the same time. I have read a lot about the elements of training each of those, but where would you start if all three need to be trained? I think house training is the most important one because once bad habits are established with that in a new place, they'll be even harder to break. How do you house train a dog if they aren't leash trained or crate trained? I actually want to paper/puppy pad train it indoors first. My plan was this: Watch her at all times, and when she shows she has to go, take her to the paper/puppy pad, which will have a dog pen surrounding it. If she doesn't go, put her in a crate so she can't go anywhere else (and hopefully won't go in the crate). Then when she shows she has to go again, put her on the paper. From this, just gradually remove the pen so she goes on the paper. The problem with this is that she isn't crate trained very well and I don't want to give her anxiety about that. Should I skip the crate and just remove her from the pen if she doesn't go, then put her back in again if she starts to go? I understand the reinforcement with treats aspect of this. Is there a better way? Night time could be a problem too.
