I got this idea from the angelvest website.
Just wanted to try it on before buying one.
So I fashioned this hoop onto Paris' harness, it worked for a while but then he kept hitting his head on the wire and thought he was trapped. Then the wire fell down and he stepped right through it.
So back to the drawing board...
The wire is supposed to bump the wall or object before the dogs' face does. Paris may need a few more lessons on how to use this contraption.
