Lol. . .yeah, at first we had to chase Darwin around the house to it on. . .now there is just a few head turns before he lets us put it on. persevere. . .we were told that Darwin would throw sommersaults and drag backwards on a halti. . .while he doesn't like it. And tries to rub it off on the grass he does walk so much better. . . .as I said earlier it should only be for a couple of months till they are routinely wslking well by your side then start to alternate between halti and normal collar over another month or so phasing out the halti he should continue walking nicely.
