Since opening in August 2007, Siena Animal Hospital has become a quality practice for pets of Summerlin and Southwest Las Vegas. Siena Animal Hospital’s goal is to provide exceptional medical and surgical care for your pets as well as to treat you, the client, with excellent service and respect.
Only 12% of all small animal veterinary practices in the United States have achieved accreditation by the American Animal Hospital Association (AAHA). Siena Animal Hospital is one of the few and the proud.
Ask about our Spay & Neuter Specials. There is a new
spay/neuter ordinance requiring all dogs and cats to be spayed and neutered unless you are actively showing them or have another legal reason to have an intact pet. In addition, there are numerous medical, ethical, and health reasons to spay or neuter your dog or cat by 6 months of age.

New clients who mention this website* can ask for a first-time complimentary exam** for any reason as well.
*Cannot be combined w/ any other discounts or promotions.
**Vaccinations, medications and any testing not included. Good for one patient only.
