Dog Myelodysplasia is a large selection of disorders found in dogs. They all begin within the bone marrow of the dog, and are the result of unusual characteristics of the stem cells responsible for the creation of other blood cells in the body. They involve the rapid creation but impaired maturation of cells within the dog. These diseases are typically categorized into two forms: acute myeloid leukemia and chronic myeloproliferative disorders.
Acute Myeloid Leukemia
This disorder tends to come up quickly, making it among the most aggressive of all Dog Cancer conditions. This Leukemia involves no maturation of the cells within the dogâ€™s body. The areas of the dog's body that are typically affected by acute myeloid leukemia include the kidneys, spleen, liver, and lymph nodes. The entire central nervous system could also be jeopardized. Infections and hemorrhaging are commonly seen in dogs with this unfortunate condition.
Chronic Myeloproliferative Diseases
This category of disorders tend to progress in a slower manner than any other form. They are often characterized by an overpopulation of cells in the bone marrow. This group can be further broken down into a number of disorders that may be experienced by a dog.
Polycythemia Vera is an example of these chronic disorders, and is known for the overproduction of red blood cells. It does not occur too often in dogs, but when it does, it tends to be found more in middle aged canines. Basophilic leukemia is a similar disease, only it is more commonly known for the rise in white blood cell count that it causes.
Symptoms of Myelodysplasia Disorders in Dogs
The exact signs experienced by a dog affected with Myelodysplasia will depend on the type of condition present which is present. Common symptoms that can be found in a number of these issues include Dog Loss of Appetite, Dog Increased Thirst, Dog Lethargy, Dog Fever, and Dog Weight Loss. These diseases can also cause Dog Vomiting, Dog Difficulty Breathing, Dog Seizures, and improper muscle functions. The cells within the bone marrow can be impaired depending on the certain condition the pet is experiencing.
Diagnosing Myelodysplasia in Dogs
The bone marrow as well as blood will be closely examined to determine a proper diagnosis of the many types of myelodysplasia disorders in dogs. Blast cells may be found around the bone marrow which can be tested. In the event that these cells are not present, the diagnosis can be shifted to believe that leukemia is the right condition that the dog has. The need for several medical examination techniques will be necessary to study the blood cells. This will allow the veterinarians to rule out other possible causes of the cell abnormalities, including those that are non-cancerous.
The method of treatment will vary greatly based on the type of myelodysplasia present in the dog. Chemotherapy is a common method to treat acute leukemia in dogs. Other courses of action may be used to reduce the overabundance or red or white blood cells. Certain medications can be administered to help keep the situation under control.
