Its a Dogs Life (1955 ) Jeff Richards, Jarma Lewis,Edmund Gwenn, Dean Jagger, Richard Anderson,

In the early 1900s, a bull terrier living on the streets of the Bowery rises from a street-tough engaging in dogfights to pedigreed show dog among the upper crust. All the while, he has two ambitions--to be reunited with his mother and to get even with his father who deserted her.
