First teaching the come:
1. Prepare a variety of tasty treats, but make sure you don't overdue you don't want your dog to get diarrhea.
2. Attach a long leash (usually called a tracking lead) to your dog’s collar.
3. Keep one end of it in your hand, while slowly walking away.
4. When you are pretty far away kneel down to the dogs level and open your arms wide, as if asking for a hug.
5. Call him to you with a cheery voice: “(rover), come!”
6. If the dog doesn’t respond, give the line a ‘quick tug’: short and sharp.
Please note: you are not to use the leash drag him towards you. It’s a quick physical reminder that he needs to listen to you.
7. As soon as your dog starts walking towards you, praise him in a calm, happy tone of voice: “Goooood boy, what a goooood boy!” Praise him when he starts to come to you,
8. As soon as he gets to you, give him a treat, or if your dog has a favorite toy give him that instead.
The "Drop it" command.
1. Hold a treat in one hand, and give him a favorite toy or a treat with the other.
2. Let him really get a good taste then hold a small piece of treat-food near his nose and say “Drop it”.
3. When he drops it give him the other treat immediately and say "Good Boy!"
Practice both exercises about 5 to ten times per day. But try to end on a high note: stop each exercise while when they do it right. Be sure to give plenty of praise at the end of the training.
