How doe the faithful dog theory overestimates the power of the advertisers?

The faithful dog theory suggests that consumers are highly loyal to brands, akin to a dog’s unwavering devotion to its owner. This theory overestimates advertisers' power by implying that brand loyalty is primarily driven by emotional attachment rather than informed decision-making. In reality, consumers often prioritize factors like price, quality, and personal experience over brand allegiance. Consequently, the theory overlooks the dynamic nature of consumer behavior, which can shift swiftly in response to market changes and competitive offerings.
