Our sweet dog Peanut lost a lot of hair at the end of his life and was always cold. These fleece vests were a godsend--they were soft against his skin, kept him warm in the summer, were a great base layer in the winter, and were cut high in the belly so that he never peed on them. He wore these every day for the last year of his life. We are so grateful for this product and the comfort it gave him. Thank you.
