Animals – Proactive treatment recommended

Rocky, a four-year-old Labrador, was recently seen in our newly renovated small animal hospital after his owners noticed large lumps under his chin. Following diagnostic testing, it was discovered that these lumps were his lymph nodes and he was diagnosed with multicentric lymphoma.

Canine lymphoma is one of the most common cancers diagnosed in dogs, accounting for approximately 15–20% of all canine malignancies. It develops from lymphocytes, a type of white blood cell essential to the immune system, and can affect lymph nodes, spleen, liver, bone marrow, and other organs.

While the exact cause remains unknown, genetic predisposition and environmental factors are thought to contribute. Clinical signs vary depending on the organs involved but may include lethargy, weight loss, reduced appetite, vomiting, diarrhoea, or increased thirst.

Diagnosis was achieved via fine needle biopsies of enlarged lymph nodes, with further tests and imaging used to determine disease stage and type.

Without treatment, Rocky’s prognosis was grave, so an 8-week chemotherapy protocol was commenced. Each week he visited the clinic for cuddles with the vet nurses and an infusion of his chemotherapy drugs.

Rocky has tolerated his chemotherapy extremely well, continuing to enjoy walks on the farm and family play times throughout his therapy. His case highlights how early diagnosis and proactive treatment can help dogs with lymphoma combat the disease while still maintaining a good quality of life.
