Siena Animal Hospital has been providing superior and compassionate care for dogs and cats in Southwest Las Vegas, South Summerlin and the surrounding areas since 2007.

Come in for a tour of our hospital - we'd love to show you around!

Siena Animal Hospital, your veterinary hospital in Southwest Las Vegas, is proud to offer the following services for your pets: preventive and critical care veterinary medicine, routine exams, vaccinations, surgery, dentistry, digital radiology, dental digital radiology, ultrasound, client education, microchips, wellness plans, customized senior plans, and the latest state of the art diagnostic technique called PENNHIP for predicting hip problems.

While Siena Animal Hospital is not a shelter, from time to time we do take in homeless pets and attempt to place them in forever homes. If you are kind enough to adopt a pet from us, we will happily provide your new family member with free annual exams and vaccines for life. We also accept donations for the Siena Stray Fund that will go directly to help defray the cost of these animals' care.
