The most important aspect of a dog harness is the fit. A properly fitted dog harness keeps your pet comfortable and allows the features of the harness to function as intended.
Girth is the measurement of your dog’s chest. Wrap a soft tape measure around the broadest part of their chest and use the girth to determine the range of harness sizes that will work. Small dog harnesses range from 8 to 23 inches, while large dog harnesses can be from 22 to 44 inches.
Once you know the size, consider which features are helpful for you and your pet. A dog harness with a handle works well for dogs undergoing training exercises. Easy-walk dog harnesses help rein in a pup who's particularly excitable.
