@mirason We got a rescue a couple years ago -Mara is her name- and she had some major potty issues. Not only would she go in the house, but she would even go in her crate and then just... lie in it. (She had a very bad start in life, pretty sure she ONLY knew the inside of a kennel before she was surrendered.)
We tried so many things, but the only thing that worked for her was doggy diapers. She did NOT like going potty in the diapers, and she didn't like wearing them either, so it didn't take long before she didn't need diapers in the house anymore. The crate took a LOT longer, and she still has tons where she regresses and has to be a diaper baby for a few days while in the crate at night. However, those times are getting fewer and farther between as time goes by.
The other thing that has been INTEGRAL for her success is routine. Making sure she has certain SET potty times (before daddy goes to work, as soon as daddy gets home, right before dinner, etc) has helped a ton, too. Other than that, she goes outside when she rings the potty bell. And if she's being a distracted, yard-eating monster, she gets a few warning "leave-it"s (or a couple minutes) and then she comes inside whether she's pottied or not.
Best of luck to you! Potty training can be so hard and SO frustrating, but there's light at the end of tunnel, I promise!
