Absolutely recommend them! Nobody local to us could treat a bird in an emergency so we immediately drove the two hours to go here. They checked us in immediately as we arrived and offered us snacks and beverages. They were quite busy but checked in on us to make sure we were okay during the wait. The staff were all so kind to us. They explained everything very thoroughly, allowed my husband and I time to discuss treatment options and make an informed decision. I was quite emotional and they were extremely understanding, patient, and supportive. I hope I never need their services again, however I would absolutely return if ever needed.

We had a really positive experience here. The team did an amazing job walking us through everything in an approachable and transparent way, which helped us feel confident in making decisions for our dog’s care. I loved the space! It felt communal, calm, and collaborative. Being able to stay with our dog the entire time (on dog beds, no less!) made such a difference. It felt far more comfortable and reassuring than sitting in a waiting room or small exam room for hours, especially knowing the team was close by if anything happened. One staff member, I wish I remembered her name, stood out for how gently and patiently she approached our dog. She took the time to connect with him before the exam, and it made a huge difference in how calm and trusting he was, which is not usually the case for him at the vet. Dr. Williams was also fantastic. She was honest, clear, and made sure we understood all costs before moving forward. She talked us through her thought process at each step, explained results in real time (even during the ultrasound), and helped us feel truly included in the care plan. Everything they did felt thoughtful, evidence-based, and never excessive. Even after the visit, when I called for additional records, they were quick and helpful. Overall, I can’t recommend them enough. We felt truly cared for!

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. ❤️😭🐾
