Market Factors - Growth, Barriers, and Opportunity Analysis

Expanding Pet Population and Growing Pet Ownership Rates

The steady rise in global pet ownership is one of the strongest drivers shaping the pet allergy treatment market. Pets are increasingly being viewed as family members, leading to higher adoption rates across both developed and emerging countries. According to the Pew Research Center, 62% of Americans own at least one pet, and 35% of them own multiple pets, reflecting the deepening bond between humans and animals. Similar trends are being observed in the U.K. and other European nations, where households are actively adopting dogs, cats, and small companion animals.

This growing pet population, while emotionally rewarding, also increases the likelihood of exposure to allergens such as dander, saliva, and urine proteins. As more people share their living spaces with pets, the prevalence of pet-related allergies is increasing, particularly in urban households. Consequently, there is a stronger demand for effective treatment options, including antihistamines, decongestants, immunotherapies, and biologics to manage symptoms and improve quality of life.

Furthermore, as pet ownership expands across younger demographics and families with children, awareness regarding allergy prevention and treatment is gaining traction. This trend is encouraging pharmaceutical players, veterinarians, and healthcare providers to introduce innovative therapies and accessible solutions, ultimately boosting market growth.

Underdiagnosis and Misdiagnosis to Hinder Market Growth

A significant restraint in the pet allergy treatment market is the underdiagnosis and misdiagnosis of symptoms. Pet allergy manifestations, such as sneezing, coughing, watery eyes, and breathing difficulties, often overlap with other respiratory conditions, including asthma, sinusitis, or seasonal allergic rhinitis.

The overlap makes it difficult for healthcare professionals and patients to correctly identify pet allergies, especially in households with multiple environmental triggers such as dust, mold, or pollen. As a result, many cases go unnoticed, and patients either remain untreated or receive inappropriate medications that fail to address the root cause. This delays the adoption of effective treatment and lowers overall demand for specialized allergy therapies, thereby restricting market growth despite increasing pet ownership rates.

Rising Demand for Pet Allergy Immune Supplements Signals New Growth Avenues

Pet allergy immune supplements present a promising growth opportunity in the pet allergy treatment market, as rising pet ownership is coupled with increasing awareness of preventive health solutions. Unlike conventional treatments that focus only on symptom management, immune supplements strengthen pets’ natural defense systems, helping reduce allergic reactions from within.

With growing preference for natural, holistic, and long-term wellness approaches among pet parents, demand for supplements containing probiotics, omega fatty acids, antioxidants, and herbal extracts is accelerating. This trend is further supported by the humanization of pets, the adoption of premium products, and the expanding availability of products through online and specialty veterinary channels.

Category-wise Analysis

Drug Class Insights

Based on drug class, antibiotics are leading the market segment by acquiring 34.8% share of the global market in 2025. Antibiotics are gaining attention across the globe due to their higher efficacy against infections and allergies, thereby being highly adopted by consumers.

Pets with allergies often suffer from some symptoms, such as ear infections or respiratory issues. In these scenarios, antibiotics play a vital role in alleviating the discomfort and preventing the infection and complications.

Animal Type Insights

Dogs are expected to lead the market with a 49% share in 2025, driven by their status as the most common household pets and their higher allergenic potential. Proteins in dog dander, saliva, and urine are known to be strong allergens, frequently causing asthma, rhinitis, and skin reactions in sensitive individuals.

Dogs release allergens more frequently and in greater quantities than other pets, raising the risk of household exposure. The growing trend of dog ownership, particularly in urban areas, continues to fuel demand for allergy diagnostics and treatment. Moreover, the strong emotional connection between families and their dogs makes pet abandonment unlikely, leading owners to pursue medical solutions for allergy management, reinforcing dogs as the dominant segment in the market.

The trend toward natural and holistic care is fueling the demand for herbal and organic formulations.
