We LOVE our new crates we purchased through Wayfair.com.  Our pups enjoy the extra room--having salukis, this is a MUST!  BUT, we traveled recently for the Christmas the salukis were whiney in the crate, so we switched people out...put the four whippets in the crate together, and allowed the salukis out in the van...worked like a charm!  The whippets were comfortable, and snuggly, and the salukis were all stretched out and relaxed.  Made a long trip enjoyable.  Thanks!!
