As of 2015, the 7th of November has been known as National Canine Lymphoma Awareness Day. This day is designated to raise awareness about the disease, which is a type of blood cancer in dogs that affects the lymphatic system. In this article, we discuss some of the clinical signs to look out for and what to do if you suspect your dog has canine lymphoma.
What is canine lymphoma?
Canine lymphoma is a common blood cancer in dogs and can present in several ways. Some of the more common ways include:
Multicentric lymphoma (multiple areas of origin within the body)
Alimentary lymphoma (gastrointestinal)
Mediastinal lymphoma (chest)
The disease often originates in organs involved in the immune system - lymph nodes, bone marrow, or spleen. However, it can also occur in other areas, such as the respiratory system, gastrointestinal tract, or skin.
What are the clinical signs of canine lymphoma?
The disease is more common in older pets and can arise in any breed. Canine lymphoma can affect many organ systems, and therefore, clinical signs can be hugely variable.
Clinical signs can include:
Swollen lymph nodes
Lethargy
Weakness
Fever
Dehydration
Loss of appetite
Vomiting
Diarrhoea
Weight loss
Difficulty breathing
Increased thirst and urination
Swelling of the front legs or face
Raised skin nodules or lesions
Blindness
Seizures
Due to the vast range of presenting signs, it’s important to note that they are not specific to a diagnosis of canine lymphoma.
What to do if you suspect your dog has canine lymphoma
If you have any concerns that your dog might be seriously ill with lymphoma, or any type of cancer, please contact us right away. If any of the clinical signs persist for more than a day or two, it is always best to be overly cautious and book an appointment with a vet so your dog can be fully checked over.
Diagnosing lymphoma in dogs can involve several tests. This includes blood tests, sampling via removal of a small piece of tissue, either via a needle (cytology) or surgically (biopsy), as well as imaging, such as ultrasound or x-ray.
The type of lymphoma diagnosed influences the best course of treatment for your pets and it can include chemotherapy. The most important thing you can do if you suspect canine lymphoma, is act quickly and get your dog booked in for a diagnosis. You will then know for sure if the disease is present and what treatments may be needed.
