It’s unlikely that your dog, without previous training, will do this in the first try, so make sure you reward him even if he’s halfway through. When doing this, the first times, he’ll try to get up. You need to make sure you give the reward before he gets up. Timing is crucial. Do it for up to 5 times, rest one minute, do another repetition, rest another minute and do one more repetition. At this point your dog may already do the lay-down. Make sure you’re giving him the rewards at the right time and a good caress when he does the task.
Again, do this for 3 sessions two more days and get rid of the food for this exercise.
This one, you can combine with the sit down from a far distance, but obviously the lay down depends on the basic sitting being perfect.
Now, at this point, your dog will know how to sit and lay down. Keep asking him to do this through the day, even if you don’t really need him to, as this will consolidate this exercise and will help with discipline and obedience. Consistency is key.
