Purchasing your product from internet pharmacies

If you purchase your medication from our clinic, and your pet contracts an illness covered by the manufacturer’s warranty, we will deal with the manufacturer on your behalf. We will handle all necessary paperwork with the manufacturer to receive reimbursement for any costs incurred in the treatment of your pet. You will not be required to pay any costs covered by the manufacturer’s warranty.

It is also important to note that many products that we sell come with manufacturer guarantees. However, many of these guarantees are automatically voided if the product is not purchased from a licensed veterinarian.

Finally, if you want to purchase your prescription medication from an online pharmacy, we will write you a prescription that you can use to purchase your product. We only call in or fax prescriptions to local pharmacies. Please do not ask us to call, fax, or confirm by telephone, any prescription for online pet pharmacies.

If you have any questions regarding the purchase of medication from online pharmacies, please request an informational sheet from our receptionist. This will answer any questions you may have. If it does not, feel free to ask any employee and we will be happy to answer any additional questions you may have.
