I'm a disabled Navy vet, and am training my Yorkie, Gina, to be able to serve as my service dog, I need her to be able to pick my keys, wallet, etc... . We have been going through general obedience training for the last 7 months, my question is, can anyone recommend a good collapsible clicker target stick, right now I'm using a dowel with a small ball on the end, but it's unwieldy when carrying it around. Thank you in advance.
Cheers Quad & Gina
