Measure your pet from the base of the neck to the base of the tail. This measurement is the length needed to determine what size of shirt, sweater, or coat is ideal for your pet. 2. Always go to the next larger size if your measurement is within 1 inch of the maximum. 3. We also recommend rounding up to the next size if your pet has a broad chest, bulky build, or thick coat. NOTE: Somewhat loose clothing is more comfortable for your pet and looks better than tight clothing. If in doubt, order the next size larger.
