So glad I found this company and harness. I have a dachshund x jack Russell with a JR deep chest and doxie long body - not an easy combo but the perfect fit harness fits him perfectly! No rubbing or chafing and is super comfy with the fleece lining. The additional front ring is great for a strong puller too - have almost got him walking normally after just one week in the harness. Am now raving about it to anyone who has dogs! Also love the company’s approach to finding the perfect fit where you can swap out different bits of the harness and they’ll send you different sizes until you get the right ones and only then do you send the unwanted bits back - sheer genius and what’s not to love! Brilliant customer centred service.
