Dear Pet Owner,

Zoetis is committed to the research, development and support of innovative, quality animal health care products that can help your pet in enjoying a longer, healthier life.

Aligned with our commitment is our belief that the veterinarian is central to the health and care of pets. No other individual is better positioned through training, knowledge and clinical expertise to advocate for the health, well-being, and specific needs of pets. Veterinarians serve a key and pivotal role in the lives of pets and their owners through diagnostic, prevention and treatment services.

Based on that belief, our policy is to sell our prescription medications for dogs and cats exclusively to licensed veterinarians where a direct veterinary-client-patient relationship exists. This approach helps ensure your pet receives the best possible care.

We do not sell our prescription medications for dogs and cats to retail outlets, pet supply stores, internet sites or any other distribution facility where a veterinary-client-patient relation does not exist – nor do we support in any way secondary supply to these businesses.

We do not know how our products reach these businesses, so we can’t ensure that proper handling and storage occurs – or whether these products are legitimate or counterfeit. Therefore, we will not provide any guarantee should your pet have an adverse experience or lack of efficacy after being administered these products.

We thank you for using Zoetis products and wish continued good health for your pet.

Sincerest Regards,

Steven Leder
Vice President
US Companion Animal Division
