Got one of the dog rugs and a fleece liner in the wash today. They are actually in the dryer right now. Thank you for the tip on adjusting the fit. Saves me some serious time on trial and error. Mine has the criss cross belly straps but I'm thinking I can sew a belly band to slip over the two straps so it's one wider and more comfortable belly band.
I'm just glad to have here where I can keep an eye on her. She made the journey just fine. It's a bit cold up here but nothing a mini from Iowa can't handle.
