My english bulldog is currently in a julius k9 harness but she's dinky and even though it's the correct measurements it doesn't fit her shape correctly. I just don't like it on her. I have been looking at the perfect fit harness so it definitely won't hurt her trachea and will reduce her pulling (am training her as she's 6 months but thought a harness with front D ring would help too) has anyone tried them and are they good?
