Good quality, and immediate shipping, but sizing information is inadequate, and IMHO - totally off. Made this coat unusable to me. We chose the medium based on the (minimal and barely representational - you need to say something about the chest) measurements, and the coat is way way too small. We have an 18lb 8 month Westie, just for the record. His length fit the specs, but he can barely move in the coat. The owner has commented over and over that the manufacturerer has not provided other specs. So, suggestion. Obtain one each of the sizes and measure them yourself on behalf of your clients. How hard can it be. I see that many others have had this problem. Thanks, sorry I cannot be more positive, as the coat is nice. But the shipping and service charges to Canada make the cost so high, I cannot splurge on another.
