The primary challenge in developing new drugs for pets is confirming their safety and effectiveness across different species and sizes of pets.

It’s necessary to develop treatments optimized for each species, taking into account their physiological characteristics and metabolic differences. Additionally, developing drugs suitable for the specific health conditions and dietary habits of pets is required.

This involves extensive clinical trials for major pet species like dogs and cats. Also, developing administration methods that are easy for owners and less stressful for pets is crucial.
