About South Sioux Animal Hospital

About Us

South Sioux Animal Hospital was founded over 50 years ago, and was owned by Dr. Robert Billiar for much of that time. Dr. Brooke Gilbert purchased the practice in 2013, continuing the commitment to Siouxland’s pets.  We moved to a brand new facility in August 2020, where we can continue providing exceptional service to our clients and patients. We are a full service veterinary hospital offering everything needed for quality animal care.  Our experienced staff  helps your pets feel comfortable while receiving outstanding care and treatment. We provide comprehensive wellness examinations for all your companions’ life stages, helping to ensure early detection of any potential problems. From routine care like vaccinations, heartworm and intestinal parasite testing, to more complex issues such as injuries, illness, cancer, and more, our experience, compassion, and dedication will ensure your pets receive the best care possible.

Meathead came to South Sioux Animal Hospital in the fall of 2015, after being picked up by animal control.  He had deep wounds in his neck and his ears had been damaged from what we suspect was recurrent frostbite. Meathead is positive for feline immunodeficiency virus (FIV), which is the cat-equivalent of HIV. Meathead has found a home here at the clinic as the resident office cat and you can often find him supervising the doctors while they write patient records, or curled up on a sunny chair in the break room. He especially loves when he gets new visitors that give him a head scratch and a snack! 


Youth originally came to South Sioux Animal Hospital in 2010 with a rectal prolapse and was surrendered to the hospital. Dr. Gilbert decided to get him fixed up and adopt him. He spent many happy years in the Gilbert home, but in 2023, there were some changes at home that caused Youth a little stress, so he came to live at the hospital. He’s now a happy, inquisitive office cat and getting along well with Meathead! Youth enjoys getting lots of attention during morning staff rounds, afternoon naps in his (multiple) beds in the doctors’ office, and daily belly rubs.


Anastasia is our resident Russian tortoise. She came to live at South Sioux Animal Hospital in 2021. She came from a rescue organization, so we really don’t know much about her, or how she got a crack in her shell. Russian tortoises can live to be over 40 years old. Her favorite activities include basking under her heat lamp, burrowing in mulch and hiding in her log. She also enjoys her weekly spa day where she gets a warm water soak to help her stay hydrated. Her favorite snack is dandelion greens. 

We are proud members of local and national organizations
