we went to visit the breeder yesterday, and the two puppies she had left were the 'shy' ones of the litter. they weren't afraid of us or anything, they just didnt run up to us right away like the rest of them did. once the others were put into a separate room, the puppies started running around and playing with us just like any other puppy. can a shyer puppy like these two have temperamental issues in the future, or will they be like any other goldie??
