The most important family member

Father Jack is the sweetest Beagle in the world - I think! It doesn't matter that he has only one eye because his heart is dubble sized. 
He is always hungry and Maggie says he has already a little belly, like an old man.
But it is very important that either Jim or Maggie are around him. Otherwise he starts crying and barking about his "parents".
All the people on the farm love him and also Jack loves all the people.
