Internal medicine focuses on the diagnosis and treatment of diseases and disorders affecting your pet's internal systems. At Westend Veterinary Hospital, our veterinarians have the diagnostic tools and in-house laboratory capabilities needed to diagnose a wide range of medical conditions and develop effective treatment plans.
Our in-house veterinary laboratory allows us to perform a wide range of diagnostic tests on-site, including bloodwork, parasite testing, cytology, and more. For advanced diagnostics, we partner with a specialized veterinary laboratory. Together, these resources help us identify health concerns and begin treatment as quickly as possible.
Our veterinarians manage a variety of medical conditions in areas such as cardiology, dermatology, endocrinology, gastroenterology and more. We are also experienced in caring for pets with multiple health concerns and conditions that require ongoing management.

If your pet is exhibiting symptoms of an internal condition, your veterinarian will conduct a comprehensive physical exam to diagnose the issue and create a treatment plan customized to their needs.
Our veterinarians cover all aspects of internal medicine and can treat a variety of medical conditions in the following areas:
Dogs and cats, like people, can suffer from a range of heart diseases and disorders. With the technology in our in-house vet lab, our veterinarians can examine your pet for signs of heart disease then provide you with a diagnosis of your pet's condition along with treatment recommendations.
Eye conditions can develop quickly and may affect your pet's comfort, vision, and overall quality of life.
If your pet is experiencing redness, discharge, squinting, cloudiness, excessive tearing, or changes in vision, our veterinarians can perform a thorough eye examination to identify the cause.
We offer diagnostic testing and treatment recommendations to help manage eye conditions and protect your pet's ocular health.
Skin conditions can affect pets of all ages and are often caused by allergies, parasites, infections, or underlying health concerns. If your pet is experiencing itching, scratching, hair loss, redness, ear infections, or changes in their skin or coat, our veterinarians can help identify the cause. We offer diagnostic testing and personalized treatment plans to help manage skin conditions and keep your pet comfortable.
The immune system is responsible for detecting foreign invaders or abnormal cells and beginning defensive action to protect the health of your pet. However, the immune system doesn't always work as it should, leading to immune-mediated disorders.
Anemia, arthritis, irritable bowel syndrome, hypothyroidism, allergies, and skin diseases are some of the most common immune-mediated disorders seen in dogs and cats.
Your pet's respiratory system is responsible for delivering oxygen to the body and eliminating waste gases such as carbon dioxide. Since dogs and cats are unable to sweat the way people do, your pet's respiratory system is also essential for regulating their body temperature.
In dogs common pulmonary disorders include chronic obstructive pulmonary disease (COPD), canine distemper virus, pneumonia, and lung tumours.
In cats asthma, bronchitis, parasitic worms, bacterial infections, and viruses are some of the most common pulmonary issues our vets see.
Gastrointestinal (GI) disorders are conditions that affect the pet's stomach and intestines, interfering with the their ability to digest food properly and absorb nutrients.
Pets experiencing GI problems often show symptoms such as blood in stool, constipation, diarrhea, vomiting, gas, abdominal pain, loss of appetite, and weight loss.
Sadly, cancer is a common disease in pets. However, when diagnosed in the earliest stages, many cancers in dogs and cats can be treated with a combination of surgeries, therapies, and other methods.
In dogs, commonly seen cancers include mast cell tumours, melanoma, lymphoma, and bone cancer. In cats, lymphoma, feline leukemia virus (FeLV), mammary cancer, and skin cancer are common.
Urology conditions such as urinary tract infections (UTIs) in dogs and feline lower urinary tract disease (FLUTD) in cats are also covered under the umbrella term internal medicine.
The urinary tract consists of the kidneys, tubes that carry urine to the bladder, the bladder, and the urethra that conducts urine out of the body. Urinary tract disorders in pets are common and can affect any part of this system.
Your pet's endocrine system consists of a number of glands and the essential hormones secreted by those glands. When a dog or cat's endocrine system isn't working correctly, symptoms such as skin problems and poor coat condition can become evident.
Veterinary neurology is a branch of internal medicine covering conditions of the brain and spinal cord as well as neuromuscular dysfunction. Common neurological disorders our vets see in dogs and cats include seizures, IVDD, and tumours.
Your pet's health is our top priority. If your companion requires a procedure or expertise that we do not offer, we will refer you to an experienced veterinary internal medicine specialist.
We are connected with a network of trusted veterinary specialists throughout the GTA and Orangeville areas. For select services, specialists also visit our hospital to perform advanced procedures. We will support you throughout the referral process and continue working closely with your specialist to help ensure your pet receives the best possible care before, during, and after treatment.
Targeted testing, imaging and other diagnostic procedures play a key role in providing pet parents with an accurate diagnosis of their dog or cat's condition.
Our in-house veterinary lab is equipped with a range of diagnostic imaging technologies and other equipment that allows our team of professionals to diagnose your pet's condition as quickly as possible so that treatment can begin right away.
