It's not about what I think it's the dogs opinion I am sharing here today - he loves it. Usually he is hesitant to have a harness put on him but I've noticed that he deliberately walks towards this one and puts his nose towards the hole where his head needs to go. He stand still and lets me strap him in and he seems happy in it out on walks. It also keeps him cool on hot days (judged by the fact that he hasn't had any adverse effects from the heat this year, unlike in previous years). Because he is black and fluffy he suffers from the heat indoors and outdoors so I leave it on him inside the house and he lies flat out relaxing in it comfortably. He is a happy customer!
