The only occasion on which a shank-bone is used is the Passover Seder (ceremonial meal). The shank-bone is eaten the following day, not during the Seder night.
A shank-bone (or other roasted bone with meat) is placed on the seder table to allude to the Passover sacrifice (see Exodus ch.12). It also reminds us of God's outstretched arm (see Exodus 6:6).
The shank bone, typically displayed on the seder plate during Pesach or Passover, symbolized the sacrificial lamb. The blood from the lamb was supposedly used to paint the door and window frames of Jewish households to identify them to the angel of death when it slew the firstborn sons of the Egyptians, so that it would "pass over" those houses and spare the Jewish children.
Maybe, dogs can eat any raw bone except for chicken bones. Chicken bones are very brittle and your dog might choke if they break. If they are cooked I wouldn't give him/her any bone.
Foods that Jewish people cannot eat are known as 'non-kosher'.
