Osteosarcoma in Dogs

Like Human beings, dogs too exposed with many diseases. Among them, few diseases are curable and others could be critical. Typically, Osteosarcoma shortly named as (OSA) is the most common bone tumor disease noticed in dogs and has high metastasis in ability. More than 80% of malignant bone tumor mainly occurs in large breeding dogs such as German shepherd, Boxer, Rottweiler and Dober Pinscher etc. Among all such diseases, osteosarcoma is an aggressive form of cancer, which affects the bones of dog. Moreover, this type of tumor is found around 5% in canines. The most affected part of the dog, according to osteosarcoma disease is the limb, which tremendously affected by cancer. Thereby, this part is completely amputated followed by aggressive chemotherapy. By following proper treatment, we could cure them. It has higher rate of malignancy in dogs.

What are the Common Signs and Symptoms of Osteosarcoma in Dogs?

Initially, the most common early signs of this disease are bone Swelling and inability to bear his weight. Although, if symptoms are not identified earlier, will lead to bone fracture in large breed dogs. Most of the time, the symptoms of osteosarcoma in dog is associated with location of the tumor, where it grows on the extremities on the limb (i.e) below the joints. This tumor is mostly found either inside or near the growth plates. If the signs and symptoms of this disease are not found earlier, that will lead to the tumor cancer and spread to the lungs. However, few symptoms could cause mimic osteosarcoma, nothing but the fungal infections of the bone. If there is more fungal infection, we could cure them.

Veterinarian doctors can look at the bone patterns of dog, by using x-ray technology and could find out either the tumor is growing or not. If situation of symptoms is ordinary, then they would conduct an alternative test to find out osteosarcoma disease and recommend good treatment for dogs.

What are the risk Factors of Osteosarcoma in Dogs?

The ethiopathogenesis of osteosarcoma in dogs cannot be known, but predisposing factors such as sex, body, weight would lead to development in dog’s health. Ultimately, it is found that dogs with body weight more than 40 kgs is found to get predisposed than smaller dogs. Many research studies revealed, that neoplasm affects male often than female dogs.

Therefore, location of a neoplasm tends to increase the hazard of metastasis and their morality. The bone cancer is localized at distal radius corresponds to lower hazard of metastasis. In many situations, there are dogs which breeds have predisposition to osteosarcoma in dogs. This disease can affect all breed of dogs and often found in larger breeds.

How to Diagnose the Osteosarcoma disease in Dogs?

Generally, Diagnosis were performed to find, whether the dog is affected by particular disease or not. Diagnosis is mainly carried out based on physical examination in dogs. Thus, with the help of radiography and by using the fine needle, biopsy is performed to identify type of tumor in Dogs. Mostly veterinarian doctors use X-ray for the treatment in chest of the dogs. For this reason, the chest would be in metastatic risk. Followed by Radiography and X-ray, Blood test, MRI scan are recommended by the doctor for further diagnosis in dog. By diagnosing the dog with TNM system (Tumor, Lymph node, and metastasis) helps in differentiating three stages of disease.

Stage 1 includes Low-grade (G1) without metastasis (MO) occurrence evidence.

Stage 2 includes High-Grade (G2) without evidence of metastasis (MO).

Stage 3 includes lesion with metastasis disease (M1).

Treatment of Osteosarcoma in Dogs

As, everyone familiar about Osteosarcoma disease in dog is very aggressive and requires much intensive treatment. After completion of diagnosis in dog is further followed by treatment. There are many different types of treatment options available depending upon the stages of tumor and financial position of the dog‘s Owner. Initially, the treatment starts with amputation followed by the chemotherapy treatment. The best treatments of successful chemotherapy available in market are Cisplatin and carboplatin. Carboplatin is considered much costlier and still easier to use it. The doctors should offer good treatment to dogs for better recovery.

The doctors often recommend radiation therapy treatment, which helps to reduce the pain and inflammation in joints. In case the dog’s owner does not want surgery, they take radiation therapy treatment in dog. By Treating the disease properly, would prevent the disease from progressing. Thereby, the dogs would be in comfortable position. While providing treatment, the prognosis varies depending on overall health of dog. Studies reveal that the dogs live for many years, after successful treatment.

How can Osteosarcoma disease in Dogs could be prevented?

As, we know that osteosarcoma in dogs is extremely threatening. So we must prevent this disease in earlier stages. If the disease is not found in earlier stages and this disease is very critical and also may often lead to death. Health issues of dog monitored for the disease like osteosarcoma would easily attacked in high breed dogs. By performing proper prevented, we could control this disease.
There are risk factors such as breed, age and gender, which decides the nature of disease and their type.

In this modern world, more medical technologies available to detect this disease early and provided proper medical care to the osteosarcoma disease. If we found any signs and symptoms of cancer, we could directly get appointment schedule to consult the doctor and get proper treatment. We must not idle with the dog’s situation, for the chance of disease to get recovered.

Which among the dog breeds affected by the Osteosarcoma disease?

  • Rottweilers.
  • Labradors.
  • Shepherds.
  • Golden Retrievers.
  • Dobermans.
  • Boxers.
  • Weimeraners.
  • Great Danes.
  • Irish Wolfhounds.
  • New Found lands.
  • Saint Bernard’s.

Nowdays, canine osteosarcoma is much aggressive disease and fearful to high breeding dogs. It is a highly malignant bone tumor with high metastasis ability. Although, we are equipped with modern medical facilities to identify the symptoms and diagnosing them, chemotherapy and radiotherapy seems much effective method in treating this disease. New approaches to osteosarcoma treatment are currently under research.
