My new puppy is a white Labrador. She is approximately 4-5 months old, judging by her size. She is a rescue. An associate found her on the side of the road with her 'brother'. She stated that she took them to the vet, got them checked out and their first set of vaccinations/booster shots. She is showing disinterest in any kind of visual/verbal stimulati. She will acknowledge my actions (calling her, talking to her) but doesn't really respond to them. Like she's depressed or doesn't care. She is also acting very "skiddish" and antisocial. She seems quite scared. Her breathing is normal, she has a good appetite, and she's drinking water. She has stayed under my desk, almost out of reach ever since she came home. Should I be concerned, or just wait it out and hope she becomes acclimated to the new surroundings. OH also, no other pets in the house, and no childrens. Thanks for any help you can give me.
