You mention the depression.....
My father was born in 1918 and thus experienced the depression. His family was poor. He had no father. At an early age he was tasked to hunt for the family (his mother and younger sister). He used to tell me that his mother would give him the single shot .22 rifle and two or three 22 rounds. He was expected to return with a rabbit for each round she handed out to him. No shooting cans for fun for that kid. Tough life.
Strive to live up to the opinion that your dog has of you.
