Absolutely outstanding service. The harness I ordered arrived and it just didn't fit my pooch.I was disappointed as she is a rescue and I wanted to start her training with this harness (recommended by an accredited trainer). I didn't fully appreciate that it has 3 sections and you can have different sizes for each so that you get that Perfect Fit. I was sceptical that I would be able to return parts or get parts that would fit. I called Customer Services and waited for the "I'm sorry but you can't return it" but No, to my surprise (& astonishment) they were friendly, very helpful and listened to what I was saying about the fit on my pooch. They asked for more information about her age, weight, girth etc and said they would send out a complete other set with different sizes. I could then mix and match to try to get the best fit. They did indeed send out another one completely free of charge. The only thing they ask is that you pay for postage to return the parts you don't want. I was concerned that the parts I was sending back would have dog hair on so I called them. Once again, they were friendly and helpful and said that they understood this would be the case and that it was perfectly acceptable as long as the items were still in a saleable condition. Once again, this company more than exceeded any expectations I had. I duly found the right fit and returned the parts I didn't need. I was more than happy to pay for the return as it meant I got a harness that is the Perfect Fit for my dog. In this day and age it was an absolute pleasure to do business with this company not something I feel very often. If you are thinking of using them, be assured that they truly do offer a unique customer service experience if you need it. I am writing this wholly independently and have had no other interaction with Perfect Fit other than that mentioned above but I was so taken aback by their excellent customer service that I felt I just had to write a review. I have one very happy "in training" pooch,
