Yes, of course. However, there is one thing to check before doing so. We have many conversations with customers who do not realise how much adjustment is available on harnesses and in well over 50% of cases we can help them to adjust the harness and get it to fit. The straps can be adjusted in a number of different ways to expand or decrease the size for the neck, chest and mid/lower back fixings. If you measured your dog correctly, please trust the product and try to adjust it fully before sending it back. Alternatively, watch this video or call us to discuss. Please remember that if you return a harness due to a sizing issue, you will be responsible for paying the return postage. If you just don’t like the harness then you are well within your rights to return it. If you would like to do this, please take a look at our returns page for more information.
