Havent charged to 100% in a while, how's everybody else's 100% estimate?

We ordered a 2027 Solterra and it won't be here until early December. Meanwhile, we'd like to get a dog bed for our 100+ lb Labrador for the rear cargo area. Having it in advance would be great and maybe save us some hair issues when we first get the car. (He sheds like crazy!) We're not quite sure what would work well in the Solterra. The photo give you an idea what were looking at.

Does anyone have any recommendations on a dog bed that fits well and is pretty sturdy? (As you might expect, I'm INUNDATED with ads now for dog beds since I've done some searching for them.) I don't know if it matters, but it's the Touring XT. Thanks for your help.
