6-12 Accidents Per Day, What Am I Doing Wrong?

I have a 13 week old miniature Schnauzer. I brought her home at 8.5 weeks, and the first two-ish weeks were a breeze. Not many accidents, lots of predictability. Lately, though, potty training has become a nightmare and she’s been having accidents almost every time she needs to go, whether crated or not.

I am taking her to the vet on Friday, but I don’t think it’s a UTI as she usually holds her bladder most of the night and shows no other signs of illness. She wakes me up twice at night to go, usually by rustling in her crate (not barking), sometimes holding it up to six hours.

During the day she is confined to three spots: her sleeping crate in my bedroom, which is only large enough for her to turn around in. She has both peed and pooped in here, regardless, though almost never at night; her travel crate in my living room, which is a bit larger, and a new 4’x4’ x-pen I put in the living room once accidents started happening in the larger gated kitchen I had her in.

These days, the only time she will predictably go potty outside is right when she wakes up. Every other time it’s a crapshoot. I’ll take her out every 30 minutes if I need to, but then stare at her while she digs for weeds or stares blankly at me for 15 minutes. If I take her out after a walk, she’s too hyped up to go. If I take her out after meals and the timing isn’t exactly when she feels like going, I’ll come back inside and she’ll pee or poop right in front of me in her crate or pen.

I am at my wits end here. Any ideas? Did I get a lemon?
