They invented clifford's puppy days when the man who makes the voice of the big clifford died in 2003.
So than they invented clifford's puppy days to continue the history of Clifford.Thats when they stared the cartoon of baby clifford.
I like cliffords puppy days better i don't know why, but i think is because he is really cute when hes was a baby dog.
Clliford's best friend is geroge on clifford'd puppy days, and o Clifford the big red dog, Cleo and T-Bone is his best friends.
He was the smallest dog in his city when he was a puppy.When he was big, he was the biggest dog in the Island.
