Best Bedding Options for Dog Owners

I'm really fed up with dealing with a duvet cover. I thought I'd get better with practice, but it never got easier, especially with a king-size duvet.

For those of you with dogs that love to snuggle on the bed and need to wash your bedding frequently, what do you recommend? Do you use a comforter, even though it seems like a lot to wash? Or do you go with a quilt, which can sometimes feel flat and uninspiring? Any tips or hacks? Kicking the dog out isn't an option—I love her too much!
