Another point of note is that Snoopy
is a second hand dog
, or rather, pre owned
. When Charlie Brown
up at the Daisy Hill Puppy Farm
he was already previoulsy owned by Lila
We are introduced to Lila in the "Snoopy Come Home" episodes where Snoopy receives a letter about his previous owner getting sick and being confined in a hospital and he promptly leaves his doghouse to visit Lila.
His quest takes him on many amusing adventures along with his sidekick woodstock.
