53 Days Lab! As Shalin said please use the Leash if you are going to take you Lab out for a walk. Yes, I would rather suggest to until all the Boosters and Vaccinations to complete then take the Lab out for a walk.
Make sure she/he is not eating anything on the road as they usually tend to eat. If possible get a Shoulder Collar instaed of Neck Collar which will reduce the pressure on the Neck as they tend to run here and there, pulling you with them.
Labs are very emotional, just they want is Love Love and Love!!!
