I get the xlarge. If you're using it indoors, you can get pretty much any of the fabrics. I like the vinyl (heavy stuff) because it's easy to clean and doesn't tear up. The stuff that's like what's on outdoor furniture is pretty cool... but if they like to dig in their beds, they can wear it out. And then there's the fabric, which I've never had... so can't say anything about it.Gene said:What size bed do you buy? I checked a couple web sites for these beds and wasn't sure what size to get. For labs in the 70 pound range. Also which fabric option? I need two beds and both will be used inside.
