Dogs + Diagnosis

  • Infertility in a male dog is defined as the inability to produce a successful pregnancy in a fertile female, even with multiple breedings near the time of ovulation. The causes of infertility fall under three broad categories: failure to copulate or ejaculate, poor semen quality, and prostatic disease. This handout explains the possible causes in detail, as well as methods to diagnose and treat them.

  • 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.

  • Pets that have been diagnosed with epilepsy are usually prescribed one or more medications to prevent convulsions or seizures. Careful monitoring of epileptic pets is necessary, not only to make sure the dose of the medicine is right, but also to ensure there are no problems related to the long-term use of the medication. The most important thing to do is follow your veterinarian's instructions closely and give the medication regularly and consistently. This will ensure that the value reported on the blood test is reliable.

  • Pancreas-specific lipase is a form of lipase produced only in the pancreas and is highly specific to the pancreas. Blood values increase only when there is pancreatic inflammation. A version of the cPLI test can now be used in-clinic (SNAP fPL© from IDEXX). Ideally, the sample should also be sent to the laboratory to get an actual value of cPLI to help with treatment and monitoring.

  • Pre-surgical testing is the best way to minimize anesthetic risks and ensure good surgical outcomes. Pre-anesthetic testing consists of, at minimum, a full physical examination and may include complete blood count (CBC), serum biochemistry, urinalysis, radiographs, EKG, or more advanced testing. The results of pre-surgical testing are used to formulate the safest anesthetic plan for your pet.

  • Pregnancy in dogs can be diagnosed several different ways including blood tests, radiographs and ultrasound. The benefits and limitations of each test are discussed. Ultrasound is the gold standard for pregnancy detection and assessing viability.

  • Having your pet properly prepared for a blood test helps to ensure that the results are as accurate and reliable as possible. Preparation for these two types of tests is slightly different. Your veterinarian will give you specific instructions before your appointment. It is important that you follow these instructions exactly to ensure accurate test results.

  • The American Animal Hospital Association and American Veterinary Medical Association have established guidelines to standardize preventive health care for dogs, helping them to live longer, healthier lives. This handout provides an overview of the recommendations within these guidelines and why they are so important.

  • X-ray images are produced by directing X-rays through a part of the body towards an absorptive surface such as an X-ray film or electronic sensor. The image is produced by the differing energy absorption of various parts of the body. Bones are the most absorptive and leave a white image on the screen, whereas soft tissue absorbs varying degrees of energy depending on the density, producing shades of gray on the image. Air on an X-ray is black. X-rays are a common diagnostic tool used for many purposes.
