Cannot rate this place high enough. It is expensive but the compassion of all the nurses is truly incredible. I had to carry in my 100 pound plus dog Peter and they got to him right away. Immediately making him and us feel comfortable. We were able to stay with him the whole time even when they were doing testing. He was hospitalized overnight and we could sit with him in or next to the kennel as long as we wanted. They even baked cookies while we were there and handed them out to everyone. I’m glad to report that Peter feels much better and I wish I could make this place our main vet. They are wonderful

Five stars is not enough for the team at VEG Oak Brook. My cat was in for an asthma attack that escalated her breathing rate. The entire team was incredibly quick, calm, kind, patient, and empathetic. Someone checked up on us frequently (about every 15 minutes, and we were there 6 hours) while she was getting oxygen treatment and X-rays. Furthermore, cost was half of what I paid at another ER a month ago for the same reason. Now that we have an updated treatment plan and know what works for her condition, I am confident we will not have a flare up like this again. BUT, if we ever need assistance again, we’ll definitely be back. Thank you, to all those that helped my baby girl and were so supportive for me as well. Sagan is feeling much better and breathing at the normal rate. ❤️

Very efficient! Definitely will come back (in the event of an emergency, of course). :) Our cat, Spyder, had a urinary blockage. As soon as we entered, we explained his symptoms to the front desk staff, and we were immediately brought back. They registered him in the system, and as soon as he was assessed, they quickly identified the issue. They give owners the opportunity to watch as they cared for their pets! They also gave detailed explanations throughout the process so we understood exactly what they were doing and why. Our cat had to stay a few nights, and during that time we received texts and phone calls with updates on his progress, which gave us a lot of peace of mind. The estimate was definitely on the higher side, but all I can say is thank goodness for pet insurance. They also offered several financing options that we were able to choose from, which definitely came in handy. Special thanks to Dr.Herzhoff, Dr. Brooks, Chris and the girls up front ❤️ And to the amazing CVT who played power puff girls while our cat was in observation ❤️!
