Firstly the before and after sales advice and support is amazing, ideal for a first time dog owner or anyone trying to coordinate the correct size pieces for their growing puppy. The harness itself is of good quality and fits nicely. Our puppy (springer spaniel) has a great range of movement in it and has no complaints. For us the knowledge that we can make contact and adjust the pieces, purchase new sizing knowing it’s a safe secure fit is the biggest sales point. The only negative (if I really pick) is some of the stitching has come away from hind leg scratching but that’s after wearing it nearly all day everyday whilst camping for a week so inevitable scratches from sharp claws are to be expected. The harness remains intact & I can just replace the part as and when if needed so not an issue. Thoroughly recommend.
