My biggest single accomplishment was getting Neka to stop pulling me during a walk. From the day she came to live with me she pulled like a steam train. I spent a lot of time reading stuff and I tryed all kinds of things that I read in the internet, but nothing worked.
Then one day it hit me. Go back to the basics ...
20 Years ago I was given a cassette / VHS set call the Hollywood Dog Training System. I dug it out of a box it was stored in and I went thru it and found the section on teaching "Heel". Within 3-4 days she was pulling very little. Within two weeks she was not pulling any more. It was all about going back to square one and doing the training LITTERALLY step by step.
Although this was "the best feeling", I must admit that everytime I get a chance to teach someone about dog care, help someone train a new behiavor or cure a problem, I feel the same sence of accomplishment!!!
When Chip died, I made him a promise that I would look after ALL dogs until we met again. Helping others gives me the feeling that I've paid something forward, and at the same time, I've given something back for all the great times I got to share with Chip.
