Query: Hooded 2-Tone Dog Parka

The very best thing about this product is the seller. Although we received the wrong size twice, the seller communicates easily and promptly and is amenable to exchanges and returns, which are made quickly and without necessity to return the product before receiving its replacement. The product itself is not as insulated as it appears, but covers the body well and provides protection from the cold. I would buy this product from this seller again.
