I have a giant breed puppy who is growing very fast so didn’t want to buy a harness only to replace it in a few weeks time. The team at PerfectFit advised me on which combination of sizes would work best and avoid unnecessary changes and cost. The harness is nice and soft and I followed the video advice on how to get the puppy used to it. First time it took a while but what a difference on the walk, you could really see how much he enjoyed having a harness instead of a collar and lead. Second time I was preparing for a lengthy process but as soon as I picked up the harness the pup just sat in front of me really happy to have it put on and so easy from that point onwards. I’ve since also purchased the double ended lead which I would highly recommend, so comfortable to hold and the length adjustment is great.
