Count On us to help your sick or injured pet


Welcome. Take comfort knowing we are here to care for your ill or injured pet with a trusted and respected team of highly experienced and compassionate internal medicine and urgent care veterinary professionals.

Internal Medicine

We specialize in diagnosing and treating complex, chronic, and concurrent conditions that your dog or cat may experience.

Internal medicine consultations are available by appointment Monday – Friday – no referral needed. Please call 949-653-9300 to schedule your pet’s visit.

Urgent Care

Urgent care is for pets that need to be seen by a veterinarian for an emergency condition and your primary care veterinarian’s practice is closed or at capacity.

Urgent care visits do NOT need an appointment. If possible, please call 949-653-9300 ahead so we can prepare for your arrival and update you on an approximate wait time.

We are proud to serve Southern California pets and their people. AVSG Internal Medicine and Urgent Care is part of a family of practices, all under the same ownership and roof. Working alongside our team is Veterinary Surgical Specialists of Orange County, the largest and most experienced group of board-certified veterinary surgeons in the region.

Both AVSG and VSSOC are members of Veritas Veterinary Partners, a group of some of the finest emergency and specialty practices in the country.

Specialists in cardiology (heart and lungs), oncology (cancer care) and dermatology (allergy and skin) are also available right here in our medical complex.

What Our PET PARENTS are saying

“I came to this facility on two occasions with two different dogs. I cannot say enough good things about this facility. The entire staff, along with the veterinarians, far exceeded my expectations when it came to service, compassion, and pricing. Thank you for helping me with Rosie and your help with Buddy.”

My puppy had an ear infection and our vet was unable to get us in for a few days so we found this urgent care. The staff was incredibly welcoming, professional and attentive, both on the phone and as I waited in the tented area out front. When the vet came out to talk to me, he was warm and completely unrushed, explaining to me the treatment as well as possible causes and an inexpensive preventative measure I was completely unaware of. It did end up taking about an hour and a half but it was overall a better experience than my highly recommended vet – and $20 cheaper for the same problem. Highly recommend!

“Absolutely had a very good visit addressing Charlie’s issues. Dr. Welsh was extremely detailed and took the time to explain options/recommendations for diagnosing the issues. The medication, treatment and routine prescribed by Dr. Welsh has made 100% difference. It’s been almost 2 months, and we have been having fun beach days with great results. Definitely would recommend Dr. Welsh and the team at AVSG. Thank you for taking care of our best friend. AVSG staff were friendly and extremely caring.”
