Some puppies, despite being younger than 16 weeks, are extremely scared of things. It’s just bad luck – perhaps this type of fear is genetic, or they have had some traumatic incidents, and they find it hard to recover. Not to worry – the beauty of the puppy socialization period is that even your scared little puppy can unlearn and learn super quickly. In such cases, merely exposing your dog to different environments will not help – it might do more harm than good. They will need a helping hand and a lot of positive reinforcement to cope with new experiences. It is best to speak to a qualified behaviourist to prepare a good socialization plan that is carefully customized for you and your dog.
