Timid dog

Two main reasons that cause this shyness genectics being one, its in the DNA, and those that are born that way have to have alot of work daily put into them from the time they are three weeks until almosy a year of age, if you miss that crucial puppy stage od socializing its all uphill.

the Other come from a simple lack of socializing at all, I have a friend that won't touch the pups and and thats fine fpr some dogs and others it ruins them, they will come out of it if worked with, but can't appreciate what they never had- touch and attention.

How old is this dog?
