2. Call the dog and tell the order "come".
TIPS: When you call your dog, pull the leash toward you and praise the dog. After a few times enlarge the distance 3,4,5,6,7 meters gradually. When you finish the practise with leash put
the dog in the sitting position in front of you without leash (again 1-2 meters) and call the dog with order "come".
enlarge the distance 3,4,5,6,7 meters gradually.
good luck!!!
