Bone Cancer (Chondrosarcoma) in Dogs



This is highly aggressive and life-threatening tumor, which requires prompt treatment. Amputation or limb salvage is usually recommended in cases where there is no metastasis (spreading) of the tumor in the affected limb. For nasal tumors, radiation therapy is normally the treatment of choice. Radiotherapy may also help in prolonging the lifespans in those dogs in which tumors are inoperable.


If the tumor involves the ribs, your veterinarian may decide to remove the affected ribs and nearby lung tissues through a wide excision in order to prevent metastasis. Chemotherapy may also be recommended, but the effectiveness of this therapy has not yet been fully evaluated for CSA. Currently, surgery is the only treatment given for this disease.


Living and Management


You may be advised to revisit your veterinarian every three month for follow-up evaluation. During this time, your veterinarian will evaluate your dog to see if any metastasis has occurred. Routine X-rays will be taken of the affected part and other body areas to check for recurrence and spread of the tumor.


After surgery, you should expect your dog to feel sore. You will need to limit your dog’s activity until it heals, setting aside a quite place for it to rest, away from windows, entryways, common areas, other pets, and active children. If it is difficult to control your dog’s movement, you may consider cage rest, placing your dog’s food dishes close by for its comfort. If possible, slow walks close to home will be best, but if your dog is in too much pain to go outdoors to relieve itself, you will need to consider making a temporary space indoors for the interim, carrying your dog outdoors, or using a catheter. Ask your veterinarian for advice regarding which method would be best for your dog.


In case of leg amputation, most dogs will not have any problems learning to compensate for the lost limb and will go on to live a happy and comfortable life.


Pain management is crucial for the effective treatment of chondrosarcoma; your veterinarian will prescribe the appropriate painkillers. Follow instructions for medications strictly. One of the most avoidable causes of death for domestic pets is overmedication.


Nutrition is very important for a swift recovery and you will need to monitor your dog’s food and water intake while it is recovering, making sure that it is hydrated enough and is getting sufficient amounts of food, but taking care not to overfeed your dog. If your dog cannot take food on its own, your veterinarian will instruct you on the proper use of a feeding tube that can be passed down into the stomach for food administration.
