The amazing prong collar!

I just took Charly for a short walk, about 10 blocks, wearing both harness and prong collar, starting out with the leash on the harness & planning to switch to the prong collar if necessary. It absolutely was NOT necessary! I can't believe this! She did not make even one try at pulling me. The only thing she did was try to stop and sniff things, and a little jerk was all it took to change her mind. This after only two short lessons, and after skipping a couple of days. It's like having a new dog.
