Diagnosis

  • Fever of unknown origin is a term that is generally used to refer to a persistent fever of greater than 39.7 °C (103.5 °F) for which the underlying cause is not readily evident.

  • Heartworm disease is a parasitic disease that typically affects dogs but can occasionally occur in cats. Heartworm is usually diagnosed with a simple blood test. There are two main tests for detecting heartworm infection; one test detects adult worms and the other detects microfilaria.

  • Heartworm disease is caused by a parasite called Dirofilaria immitis, better known as heartworm. Dogs become infected when they are bitten by an infected mosquito that is carrying immature heartworms. Heartworm disease is widespread in the United States and is particularly common along the southeastern and gulf coasts, and through the Mississippi River valley. In Canada, heartworm infection is more restricted and is localized to southern Ontario, southern Manitoba, and southern Quebec, with scattered occurrences elsewhere in the country.

  • The causes of inappropriate urination include diseases (infections, tumors) affecting the kidneys, bladder and genital tract, endocrine diseases such as diabetes mellitus, diabetes insipidus, Cushing's disease and estrogen responsive urinary incontinence, as well as neurological disease and behavioral problems.

  • Increased appetite is completely normal in pets that have high energy requirements, such as growing puppies and kittens, pets that exercise strenuously such as hunting dogs, and pregnant or nursing females. Also, pets eating a poor quality food may eat more to meet their energy requirements.

  • These clinical signs are non-specific and can be caused by many different diseases or conditions. Usually increased production of dilute urine results in a compensatory increase in water consumption, but occasionally the condition is one of increased water intake resulting in the production of large volumes of dilute urine.

  • Jaundice (also called icterus) is a condition characterized by the accumulation of the bile pigment ‘bilirubin’ in the skin, mucous membranes, and sclera (the whites of the eyes), causing these tissues to become yellow in color.

  • The most common cause of lameness is trauma or injury to joints, ligaments, tendons, muscle or bone.

  • Low blood sugar is a very serious situation, and can have a lot of different causes. Testing blood sugar levels is fairly straightforward, but additional tests may be needed to determine the cause.

  • Lyme disease is an infectious disease caused by bacteria called Borrelia. The bacteria are most commonly carried by the deer tick, also called a black-legged tick.
