He was thrown away from a passing car on the street in a cold snowy winter day. Very scared at first he did not let anyone near him for days. It took a lot of effort to his fosters to gain his trust. But they finally succeeded not without the help of their own dogs who played often with him.
Now Mark is a 5 month old puppy, social, smart, very cheerful. He learns fast too. Mark is vaccinated and dewormed.
