We are having major issues with trying to housebreak Maggie, she is 13 weeks. I know she gets it because she will paw/bark at the door when she wants to go out. However, she will pee like 3x outside only to come in and immediately pee like 5 more times. It's driving us crazy! Sometimes she'll paw at the door the same time she's peeing. I thought maybe she has a bladder infection but she's on antibiotics and I've noticed no change. We've limited her water intake to 15 min every 3 hours (per vet suggestion) but that doesn't seem to help either. Help!! Any advise???
