I wanted a lightweight harness for running to avoid strain on the dogs neck (particularly when doing Parkruns) and for Lakeland walking so that I can give the dog a lift over particularly rough terrain.
I can confirm that the Flagline harness has proved to be a great success and I am very pleased with it.
Minor points are that the lifting handle is a little small. I have small hands and can only get three fingers through the strap and so for some lifting need to grab hold of the whole harness.
I would say that the harness appears well made and a good quality product
The cost is possibly a little on the high side, however, being a bit of a twit, I lost my first harness by leaving it on the roof of the car and driving off. Although my dog has boundless energy, she is relatively small and as I think we would have struggled with some of the rougher Lakeland terrain without a harness, I have now purchased a second Flagline harness and am most pleased that I did.
