Internal Medicine

Internal medicine services at AVES cover a variety of health concerns for your pet. Veterinarians at AVES see patients on a referral basis from general practitioners. Our veterinarians work hard to manage your pet’s health concerns while communicating with you and your family veterinarian. The team approach found at AVES helps ensure that your pet gets the best possible care.

The AVES internal medicine department treats unusual, difficult to manage conditions and their complications. These conditions may include but are not limited to:


Diagnosing and treating a variety of hormonal conditions such as Addison’s disease, Cushing’s disease, calcium disorders, diabetes mellitus, electrolyte disorders, and thyroid-related disorders.


Diagnosing and treating conditions related to the gastrointestinal tract, including the stomach, intestines, liver, and pancreas.

Hepatobiliary disease

Evaluating and treating diseases of the liver and biliary system, which includes hepatitis and other hepatopathies. This also includes diseases of the gallbladder.

Respiratory disease

Diagnosing and treating respiratory diseases, including upper airway diseases such as tracheal collapse and lower airway disease such as asthma, bronchitis, or pneumonia.

Cardiovascular disease

Evaluation and treatment of cardiovascular diseases, including heart disease and hypertension, in conjunction with the cardiology team when appropriate.

Kidney disease and urinary tract disorders

Evaluating and treating kidney failure, kidney disease, proteinuria, and lower urinary tract disease.


Diagnosing and treating blood and bone marrow related diseases (anemia and other disorders of both red and white blood cells).

Infectious diseases

Evaluating and treating a wide variety of tick-borne, bacterial, fungal, protozoal, and other infectious diseases.


Our internal medicine team works in conjunction with a highly skilled team of radiologists to fully understand the patient’s history and clinical findings to allow optimal diagnostic evaluation and therapeutic recommendations based on the whole clinical picture. Collection of tissue samples is facilitated by ultrasound-guided techniques as well as fluid collection from body cavities (abdominocentesis, thoracocentesis and pericardiocentesis).

Endoscopic evaluation including gastroduodenoscopy, colonoscopy, bronchoscopy, and rhinoscopy. Endoscopic evaluation is considered a minimally invasive procedure which allows visualization of the organ of interest via video and facilitates the ability to obtain biopsies and other samples for diagnostic purposes.

Bone marrow aspiration procedures. Bone marrow samples are often needed for evaluation of animals with anemia and other disorders related to red or white blood cells.

Internists work in conjunction with other specialists including surgeons, neurologists, cardiologists and oncologists to best determine the diagnostic procedures needed to obtain a diagnosis in complicated medical cases. This allows full consideration of the patient as a whole. In addition, your internist will devise a treatment plan to best address the health concerns of your pet and will work closely with you and your family veterinarian.

For more information, please speak to your referring veterinarian or call 512-343-2837.

    Basic history:

    Has your pet traveled outside of Texas in the past? If so, where and how recently?

    If you know what kind of food your pet is eating, what brand or flavor is it?

    If you don’t, can you tell us if it is a dry food, a canned food, or a homemade food?

    Is your pet currently getting monthly flea, tick, and heartworm preventive? If so, what is the product?

    To your knowledge, has your pet had any blood transfusions?

    Other than the pet we are seeing here today, how many other pets do you have and what kind of pets are they? (ex: 1 other dog and 2 cats)

    Current Concerns:

    Write the best description of how long your pet’s current signs have been happening. (some examples of clinical signs: coughing, sneezing, vomiting, not eating, being lethargic, etc)

    Options: my pet is acting normally, few days, few weeks, few months, few years

    On a scale of 1-10, please write how severe your pets clinical signs were when they started
    1 = totally normal for your pet
    10 = most severe signs you’ve ever noted

    On a scale of 1-10, please write how severe your pets clinical signs are at the current time
    1 = totally normal for your pet
    10 = most severe signs you’ve ever noted

    If yes, do you remember which treatment or medication you feel helped?

    Based on any previous veterinary treatments (diets, medications, therapies) for the current problems, have you noted any worsening of clinical signs or development of side effects?

    To your knowledge, has your primary veterinarian sent over records for today’s visit?

    Is there any other emergency or veterinary clinic we should contact to get all of your pets information for the current problem?



    Appointment scheduling is available Monday through Saturday during regular business hours by calling 512-343-2837. We recommend speaking to your primary care veterinarian about a referral before making an appointment. We do recommend scheduling as soon as you can as appointments tend to fill up 1-2 weeks in advance.

    We recommend that you bring all medications (or a list of those medications) that you pet has been taking. In general, medications do NOT need to be stopped before your appointment. Also, please bring any records (blood work results, x-rays, etc.) that you have from your veterinarian – even if they already sent them over. It is always best to have copies with you in case the information does not make it here prior to your appointment.

    We know how hard it can be to be away from your pet. If your pet has to stay in our hospital, you can certainly visit. Our visitation hours are between 9 am and 5 pm, Monday through Friday. Please call ahead and we will arrange the best time to visit with your pet.
