Female dog peeing on her bed.. help

I have a 5 year old frenchy that was spayed before she was a year old. Shes always peed on her bed (she’s had multiple and all different kinds) and I wrote it off to being young or just urinary incontinence. Well… that all changed today because I caught her in the act! I don’t feel it was a full bladder pee buy just a few drops. She’s completely house trained, was not trained with puppy pads. She’s always been a little alpha asshole and even ran over the pit we had. The pit was a couple years old when we got the frenchy and she passed away last January.

How do I stop this?! 🥴
