Looking for dog beds

since she is small, what about a seat cushion made for outdoor patio furniture? You can leave those cushions outside with no worries and just hose/scrub it off when needed. While you pup is an inside baby, it should stand up fine, and they are a lot cheaper than $70.00!
Maybe try WalMart/etc or Lowes/Home Depot. I think the (fabric) trademark is called "Sunbrella". I know you can get it at fabric/uphol stores, as well as boating stores.
 
Alternatively, you could just make a cover for your current bed out of a waterproof material - think cribs. My girlfriend (owner of Max, the giant G.R. who sleeps thru anything) bought a twin sized waterproof mattress pad and had her son sew it to fit in school. It zips on/off and fits like an extra cover for Max's regular pet bed. She said it cost her around 10 bucks at KMart. He even got school credit in class (do they still call it home ec.?)
 
For my cat (same problem, on occassion) we use a 'chuck' pad. It is the quilted fabric square you see on all the hospital beds. It is waterproof, but basiclly a 2x2' piece of fabric with some sort of liner in the middle. I just toss it in the washer and use a new one while the first one dries. You would have to put this under the original pet bed cover if your dog moves around a lot or would scrunch it up into a little nest.
 
Good Luck.

We have the cot style beds for our guys, have for years and I love them.  I got them initially to replace the bean bag beds we had years ago and to keep the dogs off the floor and help support thier joints better.  I didn't want our guys getting those rub marks on their legs from sleeping on the floor.  Our lab is now 12 and can be incontinent at times so it works out great.  I do throw a fleece pad on top as they don't like to lay on the canvas, but that is easy to throw in the wash and the bed itself can be hosed off.  They also hold water (somewhat), so if they do have an accident it will not leak onto the floor.

I made a wonderful discovery when I was bedridden for a couple months - they have these things that you can place on a bed for incontinent people.  It's not padded at all - it's just sort of a piece of soft vinyl with an absorbant flocking.  They come in many sizes, are sold as covers for diaper changing tables, or crib pads, or in the bedding section with the specialized stuff like hypoallergenic covers.

We got a bunch of these from the hospital and since then I've been using them to cover my older female's beds.  They are very soft, very washable, if she has an accident it's wicked away from her and doesn't spill anywhere, and she can still use the soft padded beds (and the couch [8|]) she prefers.  Most of them are about two and a half years old so they are quite durable.

I have this bed for Jetta. It is sturdy plastic, so it is very durable. Plus the pad is washable (its made out of the same stuff as patio furniture pads, so it can get wet).

I was going to suggest these.  My bf sells medical supplies so he gave me reusable, washable, pee pads.  Basically, you can get them at a pharmacy.  The ones I use are 3 ft. by at least 3 ft. and they absorb very fast and don't smell.  They should cost under $10 (may need to ask pharmacist to order them).  I wrap Zoe's pillow in her crate in it since it is soft too and she likes it.  You could lay it on top of the cot bed or whatever you get.  Zoe has stopped peeing in her crate but I still use it just in case.  If you need the exact name of what to ask for, let me know and I will find out the technical term from my bf.  I have seen them in dog catalogs for a lot more money.
