Hey everyone, so Lilu is now almost 1.5 years old. She has been potty trained for way over a year and we have not had any accidents or any issues at all for a VERY long time. She free roams the house everyday and still we have no problems. Yesterday it was raining pretty hard so instead of doing our usually 2 hour dog park visit we did a 30min walk and then had a doggy playdate at our house with a friend. We have done this before so its not the first time due to weather that Lilu hasnt gotten a full 2 hour play session. Like I said before we have never had this issue. After the other dog left around 8pm to the time I noticed it at 11pm, Lilu peed on the bed, right on top of the comforter. By the time I noticed she was already sleeping on the first floor.
Has this happened to anyone before? What could have caused this?
