50+ years of service and experience combined with innovative medicine and compassionate care

Oradell Animal Hospital is a unique facility in that it not only has a general practice, but also specialty practices under the same roof.   Just as in human medicine, veterinary medicine includes many different types of specialties. Specialists bring a specific understanding to the areas of internal medicine, cardiology, oncology, surgery, neurology, radiology, dermatology,ophthalmology, and nutrition.  They possess a greater knowledge of the unusual, the uncommon, or rare in both large and small animals.   To see a complete list of recognized specialist organizations, go to the web page

For major, complicated problems, pet owners are often referred to a board-certified veterinary specialist.  Veterinary specialists complete undergraduate training, four years of veterinary school, an internship and three to four years of residency training in their  field.  In addition to this extensive training, a board-certified veterinary specialist must pass rigorous examinations and fulfill the specific requirements for certification set by each specialty college. 

Our internal medicine department at the Oradell Animal Hospital consists of four veterinarians trained in the specialty of internal medicine who delve into the complex medical management of disorders in dogs and cats seven days a week along with a specialized technical support staff.  Some of the main areas of focus include immune-mediated, hematologic, kidney/urinary, hormonal/endocrine, respiratory, liver and gastrointestinal diseases.  Some of the common presenting complaints of pet owners include poorly managed diabetes mellitus, anemia, chronic coughing, inappropriate urination, and unexplained weight loss.  

The internist will perform a complete and thorough physical examination of your pet, and based on these initial findings, additional tests will be discussed.  Diagnostics available include: radiology, ultrasonography, aspiration/biopsy, bronchoscopy, endoscopy, rhinoscopy, colonoscopy, cystoscopy, and nutritional support such as feeding tube placement.  Any diagnostic and therapeutic decisions will be discussed at the time of your appointment with the individual specialist , who will be in consultation with your family veterinarian.  The specialist, technical staff, and your family veterinarian will all work together to ensure the very best care for your pet.
