With your dog sitting at your side, set off and give the command “heel” (so that your dog is aware you are about to move). If the dog gets ahead, stop and encourage it back to your side with a titbit. Repeat. To begin with, stop every three to four paces to praise your dog and give a titbit. Do not use your voice unless your dog is at your side. You can also practise this off-lead in a secure area – this makes you work really hard at keeping your dog with you, rather than relying on the lead.
A training class is not there to train your dog. Its purpose is to teach you to train your dog so you will need to be committed to train your dog for short sessions (5 minutes) several times a day rather than just simply turn up for classes! This little bit of training everyday will be repaid with a lifetime of living with a well behaved dog. You will also learn to avoid problems before they begin as well as receive help to overcome any that you already have with your dog.
