I want to know the answer to the following question:
When did the role of dogs change to be more than guardians or walking companions?
All the background I'm provided with is that "In the 1950s and 1960s, dogs were kept outside more often than they tend to be today (using the expression "in the doghouse" to describe exclusion from the group signifies the distance between the doghouse and the home) and were still primarily functional, acting as a guard, children's playmate, or walking companion.". Is that enough to answer the question?
Answer: no
