In a competitive market, enterprises should strive to offer excellent services and products while implementing robust environmental policies that not only attract customers but also foster loyalty. This study is intended to fill a gap in brand dimensions (including brand identity, brand awareness, brand love and brand loyalty) through the role of perceived environmental responsibility and the effect of perceived social responsibility to improve customer satisfaction and loyalty. A questionnaire was given to people who used milk products in Ho Chi Minh City (HCMC) to obtain customer perceptions. To test the model, 537 data samples were chosen. This study explores the role of the brand dimension on perceived social responsibility toward customer satisfaction. The results indicate that customers’ perceptions of an enterprise’s social responsibility positively influence customer satisfaction. Perceived environmental responsibility insignificantly influences customer loyalty but significantly affects customer satisfaction. Our findings imply the importance of milk enterprises engaging in environmental and social responsibility activities with brand building and implementing appropriate strategies and policies regarding their impact on the environment and communities to increase customer satisfaction and loyalty.
