Do you have a dog that loves to cuddle and burrow? Do you have a Viszla? Then you need a Cozy Cave! I had been hearing about Miles' Cozy Cave forever now, but I didn't really know what it was until he came and stayed with me for a few days. It is quite possibly the most adorable thing ever. If you say "go to bed" he will just crawl in there and curl up. He went in head first one time and knocked over a fan in my bedroom and that really freaked him out - the whole bed was scurrying across the room!
Apprantley Miles got the Cozy Cave because he wouldn't sleep through the night otherwise - he was too cold and wanted to be wrapped in a blanket (or possibly in the bed, under the covers?!). The Cozy Cave solved the problem.
Walker, another ballwalkpark Viszla, recently got a Cozy Cave as well. I got a text from his "mom" today saying that if I didn't see him in her bedroom to look for limbs sticking out of the Cozy Cave.

I have no motivation to be pushing these other than I think they are hilarious to watch dogs cuddle up in! If only my dogs liked to burrow....
