Services
We can help with just about anything pet parenthood asks of you, including primary care, preventive care, dentistry, soft tissue surgery, and more.

We provide the full spectrum of day-to-day veterinary care your pet needs to stay healthy and well. This includes wellness exams, vaccines, nutrition support, parasite prevention, and treatment for common issues like allergies, ear infections, and chronic conditions. We’re here for every stage of your pet’s life.
Urgent Care
For health issues that should be addressed sooner than a routine visit allows, but are not emergencies, we offer same-day and next-day appointments. This includes things like minor injuries, sudden changes in appetite or behavior, or signs of illness.
24/7 Virtual Care
Chat with a licensed veterinary professional anytime, day or night. Our team can help with general questions, triage concerns, and guidance on whether your pet needs to be seen in person.

We provide core and lifestyle-based vaccines to protect your pet against preventable diseases. Your care team will tailor a vaccine plan based on your pet’s age, breed, environment, and health history.

Reviews
We had an amazing first visit with our puppy Grace at Modern Animal - Costa Mesa! The facilities were spotless and modern, and the staff was incredibly attentive and friendly. The digital record-keeping via the integrated app is super convenient and makes managing Grace's care so easy. Grace even got a thoughtful goody bag for her first visit, which was such a nice touch. Overall, we’re thrilled with our experience and so glad we chose Modern Animal as our vet. Highly recommend!

The doctor and staff are absolutely amazing. I felt heard and I felt like everyone genuinely care about my pets. The app and transparency in pricing make it so much easier to manage my dog’s treatment plan and work with my budget. I cannot recommend this place more!

The clinic itself is always SPOTLESS when I'm there and the staff have always been so helpful and excited to see my dog.
Shadow (my golden) absolutely loves Dr. Jen Lassler! I have never seen a happier dog to be at the vet. She makes me feel so safe with my dog in her care and I feel like she just absolutely loves her job and it shows! I drive all the way up from San Diego to go here because it's worth it!

Could not be happier with the service and care Dr. Lassler and the staff put into Phoebe's spay. It made me feel so much better and more at ease leaving my baby. I was given updates every step of the way and given clear instructions for her after care. Thank you for taking care of my girl.

Whether you have a dog that eats a lot of socks or a cat that just pops by once a year, we’ve got you covered.
Common Questions
Routine veterinary care gives us time to check for parasites, assess coat condition, and look for early signs of pain or inflammation. We also discuss changes in appetite, thirst, or bathroom habits that can signal internal changes. These visits help us address concerns before they progress.
The team at our Costa Mesa clinic supports new puppy and kitten parents with early exams, nutrition, and vaccine timing. Essential and All Access members can chat with 24/7 Virtual Care anytime for things like help with appetite changes, soft stools, itching, teething, and deciding if a visit is needed.
We are not an emergency hospital, but the team at our Costa Mesa clinic provides full-service primary and urgent care during regular daytime hours. In the event of an urgent situation, Essential and All Access members can connect with 24/7 Virtual Care through the app for immediate advice and next-step recommendations.
The Costa Mesa clinic provides routine, preventive, and urgent care for cats and dogs of all sizes and breeds. We do not treat exotic species like rabbits, reptiles, or birds.
You can easily book a visit at our Costa Mesa clinic online or in the Modern Animal app. If you have questions, you can call 866-505-8755 between 6am and 6pm PST.
Our Costa Mesa clinic does not offer its own pet insurance plans, but we think having insurance is important because it can help make veterinary expenses more predictable over time. Pet insurance works through reimbursement, so you’ll pay for your visit and then submit a claim directly. We work with providers such as Trupanion, Pumpkin, and Healthy Paws, and more, and we’ll provide the documentation needed to file claims.
