Thank you for ordering with us. We will contact you as soon as we fill your order. This may take up to 24 hours but call us at 503-828-9177 if your order is a rush. Please note that some prescriptions may require an examination of your pet prior to re-filling. This will ensure that your pet is healthy enough to handle the potential side effects of some prescriptions and provides further confirmation that the medication is appropriate for your pet's current condition.
