24/7 Piece of Mind

Formerly known as Animal Emergency of McHenry County and renamed in 2013, Companion Animal Specialty & Emergency Hospital (CASE) has proudly provided exceptional medical care and personalized service to companion animals since 1997.  We remain the only 24/7 specialty, referral, and emergency hospital in the greater McHenry County region dedicated to caring for your pet in a warm, friendly, and responsive environment.

In addition to our long-trusted and established emergency care, our surgical and internal medicine team is ready to work closely with your family veterinary to help your pet with complex, chronic, and difficult cases. We also have uniquely qualified integrative medicine practitioners who offer complementary services such as physical rehabilitation, hydrotherapy, and acupuncture to name a few.

We know that the bond you have with your pet is irreplaceable and highly treasured. You rightly expect the peace of mind that your pet is receiving the best care that veterinary science affords. Our priority is to provide that to you by ensuring that your pet is treated as if they are our own.
