potty trained?

so after nearly a year of trying to potty train this stubborn hound in an upstairs apartment, she comes back from camp bow wow over thanksgiving break and has only had 1 accident in the span of two weeks (huge improvement from multiple times a day). wondering if they accidentally potty trained her 😂 i hope i am not speaking too soon. she also turned 1 year old that week as well. ill never understand this girl lol
