Products like Apoquel and Cytopoint (both Zoetis) reduce itching and inflammation, while Zesty Paws supports immune health.

The industry encounters risks relating to regulatory problems, product safety, counterfeit medications, and fluctuating customer behavior. The most effective way to prevent legal penalties and product recalls is to follow the rules of FDA, EMA, and regional veterinary drug regulations.
Product safety is an issue that stands out. There are some OTC medications that might cause adverse reactions in pets if they are not used appropriately. The absence of veterinary supervision can lead to incorrect dosages, allergic reactions, or drug reactions that might damage the brand's reputation and hike up the legal risks. Warnings on the product and advertising campaigns would be of help to those who do not know the correct dosage of the popular medication.
The appearance of counterfeit and subpar pet medications is a great threat to the industry's reliability. The lack of authorization on some sellers in e-commerce sites can be a platform for the distribution of the expired or banned products, which leads to serious health issues for the pets involved and erosion of trust from the consumers' side.
The first thing the companies could do would be to make the security measures against counterfeiting, implement tracking systems, and operate only through the authorized distribution channels to safeguard their products.
Moreover, the inclination of consumers towards natural remedies and holistic pet care has also had an effect on the industry for traditional OTC medications. Furthermore, the economic recession could trigger the owners to cut back on the health products that are not essential, thus raising a question over the next quarter sales. Therefore, the companies should consider a wider range of strategies such as product diversification and organic and herbal alternatives research and development investment.
