I just got a Plow and Hearth Holiday 2015 Catalog and there are crate covers in there. Page 116
Plow & Hearth - Indoor and Outdoor Products for Home and Garden. 1-800-627-1712
I have dealt with them before and found the service good.
They have a nice animal print, including dogs, and the price starts at $39.95 for a small, 25" long x 19" wide x 20"high. Larger ones cost more. They also have some cute Yorkie pillows.
Shipping $8.99. Only $4.99 shipping for greater than $85 order.
