Veterinary Specialty Services - West Introduce
When an unexpected medical crisis strikes your beloved pet, seconds count, and finding immediate, high-level care is the top priority for any pet owner in the St. Louis metropolitan region and surrounding Missouri areas. **Veterinary Specialty Services - West (VSS-West)**, located in O'Fallon, MO, is a critical resource, functioning as a multi-specialty referral practice and, crucially, an **Emergency Veterinarian Service** that is always open. This facility is designed to be an immediate extension of your family veterinarian, providing a safety net for your dog or cat when they face life-threatening illnesses or injuries, especially outside of regular business hours.
VSS-West is not a general practice clinic; it is a center for advanced medical care. The hospital’s team includes highly qualified veterinary professionals, including board-certified specialists in multiple disciplines. Their mission is to provide expert, collaborative, and compassionate care to sick and injured pets, ensuring that even the most challenging or complex health problems can be addressed right here in Missouri.

It is important for local users to understand the nature of an emergency facility. As client reviews often reflect, wait times can vary significantly. This is because VSS-West operates on a strict **triage system**—similar to a human emergency room—where the most critical, life-threatening cases are always prioritized. If you find yourself waiting, it is often a sign that your pet is stable, and you can take comfort in knowing the Critical Care team is currently focused on saving the life of a more critically ill patient.

VSS-West provides two primary categories of service: around-the-clock Emergency and Critical Care, and specialized Referral Care across numerous veterinary disciplines.

★ 5★ 4★ 3★ 2★ 1- Everyone I encountered has been kind, professional and really loves the animals. They took great care of my girl.After being here a few times, the wait times definitely vary. BUT, please remember- if you are waiting a long time, your pet is not critical… others are and need the care first. That is something to be thankful for!!Shout out to Dr Snyder, who got my girl back to health! August 21 · Ashley Michelle
- VSS was very kind and compassionate during our entire journey with them. They cared for my sweet Kora till the end and tried everything to ensure her comfort. Thank you all for the great care you provide! It does not go unnoticed 🩷🥺 August 14 · Carley Hall
- I have utilized their services twice, with 2 different pups. Our experience was excellent in both situations, one a minor transient issue last year with my yorkiepoo and last week, when we tragically lost our 2.5 y/o to an undiagnosed rare fatal disorder that came on suddenly. Forgive me for not remembering the lovely midnight shift staff members last Thursday night who worked through the night with us as we faced an unimaginable loss. You were all so compassionate and the Vet was one of the kindest humans I've ever interfaced with and I am so grateful for his care and knowledge. To the lovely lady who clipped hair from our girl for us to take home, your kind words and care were much appreciated. August 15 · Charli Prather-Levinson
- WinnifredThank you all so very much for taking such great care of our princess, you don’t know how much it means to us that you all were so caring of our girl.As of today, Sunday 02/16/2025 in the AM she finally had a small solid bowel movement. It was kinda strange for us to actually feel like celebrating a solid poop after a week like we just went through. 🤣Y’all are just the greatest!❤️❤️❤️❤️We will keep you updated as the days go by.Thank you again!Ray & Terri TibbsSent from my iPhone February 16 · Ray Tibbs
- My family and I are so thankful for Dr. Smith, the Oncology Staff and the whole team of VSS for all they did for our Lola! They were so outstanding with their attention and care for her! Lola lived a longer, fuller life because of them, and, when it came time, they made her final transition over the Rainbow Bridge much easier! We are so grateful! January 22 · Janet Jackson
