So this isn't about kids, but it's about furkids, so it totally belongs on Hellobee, right??

So I am in desperate search of a dog bed that we can keep for more than 6 months. One of our dogs vomits at least twice a week, and both our dogs shed like crazy, so we find ourselves washing the dog bed frequently. We went through probably 20 cheapo dog beds before we finally got one that we can just throw in the wash, but it's still really gross...

What I REALLY want is either:

1) A dog bed with a waterproof AND washable cover

or

2) A waterproof dog bed insert with a washable cover.

Any ideas?!? I'm this close to figuring out how to sew and making my own!! Why doesn't this exist?? Everything I've found on google and on amazon has these reviews saying "NOT waterproof" or "zippers fell apart after first wash" or "grippy knobs on bottom side of cover fall off in the dozens"... gahhhhhhhhh
