[Maximo]

Let him come to you on his own terms. Don't force affection on him. At the same time, you can start training for the "come" command using positive reinforcement. Be extra patient and never show frustration.



Always let him know he is free to go and is not being held against his will for affection. When my boys were pups, I would pick them up for a couple seconds and then let them go on their way.



Be calm and predictable around him. Talk to him casually as you go about your daily routine. Let him observe you. Sometimes too much enthusiasm and attention can scare a puppy/dog who is trying to adjust to his new home.
