The rising prevalence of pet food allergies is expected to propel the growth of the limited ingredient veterinary diets market going forward. Pet food allergies refer to immune-mediated or non-immune adverse reactions in companion animals triggered by specific dietary ingredients, leading to dermatological or gastrointestinal symptoms. The increasing occurrence of pet food allergies is contributing to market growth, driven by the expanding use of varied and highly processed ingredients in pet nutrition, which may activate immune responses. Limited ingredient veterinary diets support the management of pet food allergies by offering formulations with fewer, carefully selected components, typically a single protein and carbohydrate source, thereby reducing exposure to allergens and minimizing adverse immune reactions in pets. For instance, in December 2025, according to preprints, a Switzerland-based organization reported that over 20% of dogs and cats are affected by food allergies, representing an increase of 1.3% year on year. Therefore, the rising prevalence of pet food allergies is driving the growth of the limited ingredient veterinary diets market.

The increasing pet ownership is expected to propel the growth of the limited ingredient veterinary diets market going forward. Pet ownership refers to the act of keeping and caring for companion animals while ensuring their overall health, well-being, and welfare. The rising pet ownership is contributing to market expansion, driven by increasing awareness of mental health benefits, which encourages individuals to adopt pets for companionship and stress relief. Limited ingredient veterinary diets support pet ownership by reducing the incidence of food allergies and digestive disorders, thereby ensuring pets remain healthy, comfortable, and easier to manage. For instance, in October 2025, according to the American Veterinary Medical Association, a US-based nonprofit organization, the proportion of respondents reporting cat ownership increased to 47.6%, up from 43.5% in 2023. Therefore, increasing pet ownership is supporting and driving the growth of the limited ingredient veterinary diets market.
