Super coating solution for dogs. We used to make sleeping in a basket with a blanket, thus accumulating hair and dust, and forced to move the basket to clean underneath the covers and go to the machine. The surrélévation's a great idea, the fabric is soft and airy. Ideally, get used to the dog from small, because our 10 year's hard to change habits. Here are the guidelines sizes per model indicated on the note but not the data sheet: S size for dogs up to 40kgs, 58 kgs up to size M and size L up to 68 kg. For my dog against only 20 kg, but it is large (queen size brack), so it needs the size M. Quick and easy assembly.
