When choosing a joint supplement for your Chihuahua, the most important consideration is the size of the chew or tablet. Chihuahuas have tiny mouths and can choke on large pills, so look for small, soft chews or powders that can be mixed into food. Our editorial team researched the best options for this breedโ€™s unique needs, including their predisposition to patellar luxation and dental issues.

Chihuahuas often have sensitive stomachs, so supplements with natural ingredients and no artificial additives are preferable. We focused on products with proven joint-supporting ingredients like glucosamine, chondroitin, and MSM, while avoiding fillers that could upset your dogโ€™s digestion.
