Those look very nice. I use harnesses for Eddie due to neck issues that presented as a severe limp right front leg/shoulder. A good friend/chiro felt around and thought it was actually neck, so we do "gently pull his head off' stretches when he seems stiff and that , combined with a 'step-in' harness has made a huge difference. I hope your Nicky is better soon and that the harness helps him as much as one helped Eddie.
