VEG in Costa Mesa is such an exceptional pet hospital. Each time I've called to assess if we should bring our dog in, I spoke to the on-call doctor within 5 minutes. The staff is so great and kind and really treats your pet like family. My dog was hospitalized overnight and I could call at any time to check on him, received text messages with updates throughout the night, and when I came in the next day, a tech was sitting in the kennel with him because he was so anxious. Triage was super easy. The open concept of the hospital was really cool because you never had to leave your pet's side and can always see the techs and vet and ask questions. Dr. Nikki Smith was so amazing! She sat with us and explained everything that was happening, and she answered every single one of my questions. Adrianna was fantastic with Kaisen. When we went in for his recheck, he immediately recognized her and got so excited. We were able to be with him the whole time and never had to leave his side if we didn't want to. Very happy with the service. It is a bit pricey, but you receive exceptional care so it's a give and take.

I truly cannot say enough amazing things about VEG ER for Pets. We rushed our dog Rue there after noticing she was suddenly breathing very strangely, and within hours we found out she had pneumonia. It was one of the scariest nights of our lives, but the team at VEG made us feel supported, informed, and cared for every step of the way. Our regular vet told us that Rue needed a higher level of care and specifically recommended VEG because of the resources and monitoring they could provide, and I’m so grateful they did. From the moment we walked in, the staff treated Rue with so much love, urgency, and compassion. The night team especially was absolutely incredible. They were patient, inclusive, comforting, and constantly kept us updated on how she was doing. Even though they were clearly busy, they never once made us feel rushed or unimportant. What stood out most was how genuinely caring everyone was. You can tell the people there truly love animals and care deeply about the families walking through their doors. They made an incredibly emotional and stressful experience feel so much more manageable, and that meant everything to us. Thankfully, Rue responded really well to treatment and is now back home recovering comfortably in her own bed. We are beyond grateful for the level of care, attention, and kindness VEG gave both Rue and our family during such a difficult moment. Thank you again for taking such amazing care of our girl. 💕

this place was super awesome and i’m so glad i took my bunny here when she had an injured leg. immediately i felt welcomed, and i knew my bunny was going to be in good hands. the entire building was organized, clean, and the exam rooms were very private and comfortable. much more comfortable than a human doctors office that’s for sure! the veterinarians and the techs were so incredibly friendly, helpful, and kind. as a nervous bunny-mom, they eased my anxiety and treated my baby with such gentle care and respect. they were informative and supportive, and gave me plenty of tools to care for my bunny’s needs. i would recommend this place in a heartbeat.
