I bought a gentle leader harness yesterday which attaches the lead that the chest. WHAT A DIFFERENCE!
I tried her with a halti which she loathed, flung herself on the ground and refused to move a cm.
It is easy to get off at the park so she can run, brilliant. The walk down was a pleasure and she kept looking at me as if to say "what next?" soooo different from the yank and crank.
