We would like to  introduce Jac, and his new best friends, Carballo and Barbara Lopez. Jac is a Rottweiler mix puppy who is about 4 weeks old when this  picture was taken on  May 2, 2003. Right now he is very tiny, weighing only 3.35 pounds, but  with  lots  of love and good care, Jac will grow up to be a fine, devoted family member.
