A biopsy is one of the more common diagnostic procedures performed in dogs. Biopsies provide valuable insight into the type of cells in an abnormal area of skin or a skin growth and whether the growth poses a more serious health threat to your pet. Either the entire mass or a small representative section of skin is removed and submitted to a veterinary pathologist, who will perform a histopathology analysis. The pathologist will attempt to determine the nature of the lesion, identify the type of cells and their relationship to each other, as well as any evidence of malignancy.
The causes of abdominal enlargement include an increase in intra-abdominal fat due to simple overall weight gain because of excess calories or insufficient exercise. A redistribution of fat into the abdominal cavity may occur with Cushing's disease.
Coughing can have many different causes. The search for answers starts with a complete history and physical examination. Additional diagnostic tests may be needed and your veterinarian may recommend doing screening tests. These are a series of simple tests that provide information about the overall health of the pet and may provide further clues about the underlying problem.
Diarrhea can be caused by many different things, some easier to diagnose than others. Simple diarrhea with no other clinical signs may not require diagnostic testing, but if diarrhea is ongoing or your pet is showing other clinical signs then baseline diagnostic testing including complete blood count (CBC), biochemistry profile, urinalysis, and fecal testing may be recommended. Additional diagnostic testing may be required depending on the results of these tests.
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.
