5 stars for dog liking this ball-bed, however the cover is cheap and poor quality, about as durable as cheap tights covering the cover.   My dog ripped holes in it in no time -- I'd like to get a replacement COVER, but if I have to buy a new bed just to get the cover it would be a total waste.  Could wayfair or manufacturer please reach out if replacement cover is an option?   I cannot find any info about that.
