only have visual information, but any ideas or help on where to look/start would be appreciated. 

 it was a small dog, i'd say 12-15 pounds, very lean, almost fox-like, with long, silky black hair.  it was not a terrier.  never seen any dog like this and am not good with dog breeds anyway.  if anyone has any ideas on this breed, i would really appreciate it. 

 thanks :)
