Companion animal obesity is a common and growing health concern associated with reduced quality of life and increased risk of metabolic, orthopedic, and other chronic conditions. Weight management in dogs and cats has traditionally relied heavily on dietary modification, caloric restriction, increased activity, and behavioral management, but maintaining meaningful and sustained weight loss can remain challenging. 

At the same time, advances in metabolic disease, gut-hormone biology, and other areas are creating new approaches to weight loss and long-term weight management. Such therapeutic interventions may act through a wide range of mechanisms, from appetite and satiety pathways to energy expenditure, metabolism, and nutrient utilization. 

As innovation in this field expands, there is an opportunity to better understand the technologies and products being developed specifically for companion animals and to identify approaches with the potential to improve weight loss and weight management in dogs and cats.
