Make sure that when you measure for an Aspen Parka jacket that you measure from the withers (ie centre of shoulder blades) to the start of the tail. DO NOT measure from the collar as this will give you a jacket that is too big!
If you measure between sizes or your dog has a large chest, it is worth going up a size.
