While driving cross-country our pup Chase developed an eye infection. We were stopping overnight in St Louis and found VEG Brentwood close by to our hotel. The care we received was amazing - kind, efficient, high quality. Chase’s issue was straightforward, but it was obvious this location is capable of handling any type of critical condition that comes at time with compassion and expertise. We are so happy to have found and will now definitely be using this group in the future for any issues as they have locations throughout the whole country. Thank you!

We are truly grateful for the care and love VEG gave to us when our little Rebel was not okay. Dr. Melissa Kane took time to explain what was happening and assured us that the situation, while scary, was not life threatening. From the moment we arrived, we were greeted with care and love. We were able to stay with Rebel the entire time. Hopefully, an emergency does not happen again, but if it does, we will go here every single time.

I don’t even know how to start this review….The doctors and nurses at VEG saved my dog Arrow’s life! He had consumed a toy, and it was lodged in his lower stomach. It was at a critical point where he wouldn’t throw it up, and couldn’t pass it. Our options were mostly for surgery. They wanted to try to scope it out first before resorting to opening him….I don’t know how, but these women found it, grabbed it, and pulled it out safely with minimal healing or damage to him. It was a true miracle!! Dr Williams was our primary doctor who inserted the scope, and Dr. Cassie K was the one to clamp and pull out the toy. She had marks on her hands from the grip - but didn’t let go. I’m so thankful to all of them, truly! The nurses were so kind, smart and quick with anything he needed, and made him feel special and comfortable. Thank you to everyone there- I still have my precious boy because of you. ❤️😭🐾
