i changed from the traditional harness to the Puppia because i felt she was more secure in the Puppia. She cant get out of it, she got out of the traditonal harness and her hair always knots with the traditional harness as well. i found the Puppia harness cheap on this site and i had to return for a smaller one and they are great people to work with
