I am a professional behaviourst and expert gundog trainer with many years of first class experinence to back me up.
Yes I too used clikers but I also carried out very many years of research on the auditaury sense and a vast variety of stimulants. I spent several years research on broadkast frequencies to find out which was the best fequency for dogs to respond in a training situation.
Clikers are now out of date, I have invented, with much painstaking research and dedication, the jingler, it can be used for sits, heels, downs, toilet training and long range recalls to mention but a few effective behavioural modifications, please feel free to see my demonstartion of my invention on youtube
Presenting to you 'The Jingler'
