To order this item, we will need information about your pet and vet to ensure you are authorized to purchase. Once your order is received, your vet will be contacted by us for up to 7 business days for vet-authorized item(s). Due to COVID-19 with limited business hours at some vet clinics, we’re experiencing longer than usual authorizations. Upon vet approval, we'll release your order for your preferred shipping method. If vet approval is not provided after 7 business days, the order will be canceled. We'll send you an email when your order is ready for shipment or pickup.
