While you can purchase canine
arthritis supplements over the
counter, ask your vet for a brand recommendation and dosage amount, or ask him to prescribe a particular prescription
dog food.
A veterinarian can also prescribe a therapeutic food formulated with
arthritis in mind, which is a more reliable bet than a
dog food for
arthritis that you can buy over the
counter, as it is more likely to have gone through clinical trials by the company.
