Dogs + Diagnosis

  • A fecal occult blood test screens for the presence of hemoglobin (a component of red blood cells) in a fecal sample. Many conditions can cause blood to appear in the stool including intestinal ulceration, neoplasia, dental disease, and parasites.

  • Fine needle aspiration is a useful tool to collect samples for cytology and is often used to diagnose abnormal lumps on your pet's body as well as evaluation of fluid samples and tissue surfaces. It is relatively simple and inexpensive but can provide a lot of information. Depending on results, further tests may be indicated to best help your pet.

  • Flow cytometry is a laboratory technique that can be used for counting, examining, and sorting cells. A sample is passed through a light source and as the cells move through the path of the light source, they scatter the light in different ways.

  • Food allergies can be problematic for many dogs, especially after years on the same diet. Clinical signs may manifest as gastrointestinal or skin problems. Some animal proteins are the most common causes and strict avoidance is the best way to treat affected dogs. An eight to twelve-week elimination diet trial on a special veterinary diet is the only definitive method to diagnose a food allergy and, in some cases, the veterinary diet may need to be continued long-term.

  • Gastrointestinal endoscopy uses a flexible tube with a camera or viewing port to inspect the esophagus, stomach, and first part of the small intestine, or the colon. The endoscope cannot reach all areas of the small intestine, so other tests may be needed to diagnose disease in these areas. 12-18 hours fasting and enemas are required prior to endoscopy depending on the area being studied.

  • Genetic (DNA) testing is readily available, whether you are using it for fun to find out what breeds your pet is made up of or if you are looking into possible medical conditions. DNA samples can be collected either from a cheek swab or a blood draw. Knowing which breeds your pet is made up of can help you and your veterinarian prevent or prepare for health issues in the future.

  • A Holter monitor is a portable device used to continuously monitor the electrical activity of the heart and can be an effective and non-invasive way to help your veterinarian evaluate heart conditions, especially when trying to determine the cause of fainting episodes or evaluate treatment. Many dogs are not bothered by it and ignore its presence.

  • Infertility in a female dog is defined as the inability to conceive and deliver viable puppies, even when mated multiple times with a known fertile male surrounding the time of ovulation. This handout outlines the varying causes of infertility in female dogs and how they may be diagnosed and treated.

  • Meningoencephalitis is a term referring to inflammation of the brain and the surrounding fluid and tissues. Meningoencephalitis of unknown origin is a term used to describe those cases of meningoencephalitis in which MRI and cerebrospinal fluid analysis indicate the disease but diagnosis through histopathological analysis is not possible. Treatment typically involves immunosuppressant drugs, sometimes with the addition of antibiotics. The prognosis depends on several factors, which are also explained in this handout.

  • If microalbuminuria is detected, your veterinarian will likely recommend further testing to look for hidden disease. The choice of tests may vary but could include routine blood tests and urinalysis (see handouts “Complete Blood Count”, “Serum Biochemistry”, and “Urinalysis” for more information). If there is no evidence of underlying illness, then regular check-ups every 3-6 months, including microalbuminuria testing, may be recommended to monitor your dog’s health status and to watch for any changes.
