    All of the flowing ARE true causes of urinary inconteincence in dogs, but which is the most common cause in female dogs?

    • Cystitis

    • Psychogenic polydipsia

    • Spinal cord disease

    • Canine cognitive dysfunction

    • Lack of estrogen

    • Ectopic ureter

    Correct Answer
    A. Lack of estrogen
    Explanation
    Lack of estrogen is the most common cause of urinary incontinence in female dogs. Estrogen plays a crucial role in maintaining the tone of the urethral sphincter, which is responsible for controlling the flow of urine. When estrogen levels decrease, the urethral sphincter weakens, leading to urinary incontinence. Other causes such as cystitis, psychogenic polydipsia, spinal cord disease, canine cognitive dysfunction, and ectopic ureter can also contribute to urinary incontinence in dogs, but lack of estrogen is the most prevalent cause in female dogs.

    In cats, almost always caused by FeLV.

    • Fibroscarcoma

    • Epulis

    • Squamous cell carcinoma

    • Lymphosarcoma

    • Basal cell carcinoma

    Correct Answer
    A. Lymphosarcoma
    Explanation
    Lymphosarcoma is a type of cancer that affects the lymphocytes, which are a type of white blood cell. In cats, it is almost always caused by the feline leukemia virus (FeLV). FeLV is a retrovirus that weakens the immune system and makes cats more susceptible to various diseases, including lymphosarcoma. Lymphosarcoma can affect various organs and tissues in the body and can cause symptoms such as weight loss, enlarged lymph nodes, and lethargy. Treatment options for lymphosarcoma in cats may include chemotherapy, radiation therapy, or supportive care to manage symptoms.

    By the time a the dog's owner notices an issue, it has become a generalized condition.

    • Fibroscarcoma

    • Epulis

    • Squamous cell carcinoma

    • Lymphosarcoma

    • Basal cell carcinoma

    Correct Answer
    A. Lymphosarcoma
    Explanation
    Lymphosarcoma is a type of cancer that affects the lymphatic system, which is responsible for fighting infections and diseases in the body. It is often difficult to detect in its early stages because it can be asymptomatic or present with vague symptoms. By the time the dog's owner notices an issue, it suggests that the cancer has already progressed and become a generalized condition.

    Multiple lymph nodes in a regional area

    • Stage I

    • Stage II

    • Stage III

    • Stage IV

    • Stage V

    • Substage a

    • Substage b

    Correct Answer
    A. Stage II
    Explanation
    Stage II refers to the stage of cancer where the tumor has grown larger and may have spread to nearby lymph nodes, but has not yet spread to other parts of the body. In this case, the presence of multiple lymph nodes in a regional area suggests that the cancer has progressed beyond Stage I, where the tumor is confined to its site of origin.

    Grading system based on how well cells are differentiated.

    • Histiocytoma

    • Osteosarcoma

    • Lymphosarcoma

    • Mastocytoma

    Correct Answer
    A. Mastocytoma
    Explanation
    The grading system based on how well cells are differentiated refers to the evaluation of the extent to which cells in a tumor resemble normal cells. Mastocytoma is a type of tumor that arises from mast cells, which are a type of immune cell. In the grading system, mastocytoma may be assigned a higher grade if the cells are poorly differentiated, meaning they do not closely resemble normal mast cells. Therefore, mastocytoma is the correct answer as it aligns with the grading system based on cell differentiation.

    • Histiocytoma

    • Osteosarcoma

    • Lymphosarcoma

    • Mastocytoma

    Correct Answer
    A. Osteosarcoma
    Explanation
    Osteosarcoma is a type of bone cancer that commonly affects dogs. It is known for its poor prognosis, meaning that the outlook for dogs diagnosed with osteosarcoma is usually not favorable. This type of cancer is aggressive and can spread quickly to other parts of the body. It is considered one of the worst types of cancer in dogs due to its high metastatic potential and low survival rates.
