This is our 4th Perfect Fit harness, his baby one, and now his 3rd adult one. As always they fit perfectly. We have this new one in yellow as a spare for when his red one is wet, we also have one in orange which is intentionally a bit big so his jumpers and coats fit under the harness in winter! These harnesses are escape-proof if you have a Houdini on your hands and are durable and easy to wash. It's also great to have the D-ring on the back for attaching ID tags if your pooch doesn't wear a collar. I would never have any other harness for Henry and frequently recommend them to other dog owners who stop and admire his harnesses and ask about them. The wonderful customer service team are always extremely helpful and goes out of their way to ensure your pooch has the right fit and the website is easy to use. Pawfect!
