The dogs segment dominated the market for pet supplements and held the largest revenue share of 43.2% in 2021. The segment is expected to maintain dominance over the forecast period. Dogs are the most popular pets around the world and the adoption rate of dogs is extremely high. According to National Pet Owners Survey conducted by the American Pet Products Association 69.0 million households in the U.S. own a dog. Companies have been introducing new supplements for dogs, which will further propel market growth over the forecast period. For instance, in October 2021, Greenies, a brand of Mars and Affiliates, launched a line of dog supplements targeting mobility, immune system support, and skin and coat health. These products are free from artificial flavors, artificial preservatives, and fillers and are formulated with high-quality ingredients.

However, the cats’ segment is projected to register the fastest CAGR of 6.1% in the market for pet supplements from 2022 to 2030. It has been observed that cats provide greater comfort and companionship to their owners, which in turn has increased the demand for cat food products including supplements. According to an article published in CNN health, in November 2021, approximately 30% of the American public suffers from insomnia and at least 25 million adults suffer from obstructive sleep apnea, and sleeping with cats might help perpetuate insomnia. Thus, the benefits of owning a cat have been boosting their adoption and hence, creating opportunities for the segment.
