Understanding Cancer in Dogs

Helping you navigate a difficult diagnosis with clarity, compassion, and care

At Allambie Vet, we know first-hand how heartbreaking it can be to hear the word cancer in relation to your beloved dog. Hearing this diagnosis can be confronting, bringing feelings of fear, sadness, and uncertainty. However, it is important to remember that not all cancers are the same, and many are treatable.

Veterinary medicine has advanced significantly, and there are now more treatment options than ever before. As your veterinary team, our role is to support both you and your dog throughout the process, whether we are aiming for cure, control, or comfort.

We are also able to offer oncology appointments and chemotherapy treatments right here at Allambie Vet. This means you and your dog can receive advanced cancer care in the comfort of a familiar, supportive environment, surrounded by a team you already know and trust.

We also understand the emotional rollercoaster that comes with a cancer diagnosis not just as vets, but as pet owners ourselves. Many of us have faced this journey with our own pets, and some of our team are currently going through it. That personal experience drives us to provide not only the highest standard of veterinary care, but also the compassion, understanding, and support you and your pet need every step of the way.

How Common is Cancer in Dogs?

Cancer is sadly common in dogs. Around 1 in 4 dogs will develop some form of cancer in their lifetime, and this increases to 1 in 2 dogs over the age of 10. Some breeds have a higher genetic risk, while age and environmental factors such as exposure to smoke or UV light can also contribute.

While a diagnosis can be confronting, many cancers can be managed effectively, particularly when detected early.

Signs and Symptoms to Look For

Not all cancers present with obvious signs, which is why regular check-ups and close observation at home are so valuable. Things to look out for include:

• Lumps or bumps that are growing, changing, or newly appearing

• Persistent lameness or difficulty moving

• Unexplained weight loss or reduced appetite

• Behavioural changes or decreased energy

• Changes in toileting habits, including urination or bowel movements

• Bleeding, bad breath, or wounds that do not heal

While these signs are not always due to cancer, they are worth investigating if they persist.

The Diagnostic Process

If there is concern about cancer, we may recommend some combination of the following diagnostic tests:

• Blood tests – to evaluate general health and organ function

• Imaging – such as X-rays, ultrasound, or CT scans. More advanced imaging such as MRI and PET scans are also becoming available in the veterinary industry

• Tissue sampling – using a fine needle aspirate (FNA) or biopsy to collect cells for analysis

These tests help us determine what type of cancer may be present, whether it has spread, and what treatment options are available.

If you are coming to us for a second opinion, we may still recommend additional testing. Even if some diagnostics have already been performed, repeating or adding specific tests can give us the most accurate and up-to-date information before deciding on the best course of treatment.

As part of the diagnostic process, we may also perform what is known as “staging”. Staging assesses the extent of the cancer how large it is, and whether it has spread (metastasised) to other parts of the body. This step is essential in planning treatment, as it helps determine the most effective options, estimate prognosis, and ensure that the treatment goals match your pet’s individual needs.

Treatment Options at Allambie Vet

Every dog and every cancer is different, so we create tailored treatment plans that prioritise both longevity and quality of life.

Our in-house cancer care includes:

• Oncology Appointments – We compile all relevant information about your pet’s diagnosis and submit the case to a trusted veterinary oncologist. The oncologist provides an up-to-date written report outlining the diagnosis, recommended treatment options, and a personalised plan. We then sit down with you to discuss these options, answer your questions, and work together to create a plan that is in the best interests of both your pet and your family. 

• Chemotherapy Treatments – We can provide chemotherapy at Allambie Vet, allowing your dog to remain in a familiar and comfortable environment. Most dogs tolerate chemotherapy very well, with only mild and temporary side effects, and many continue to eat, play, and enjoy their daily routines during treatment.

• Supportive and Palliative Care – When cure is not possible, we focus on comfort, pain management, appetite support, and ensuring the best possible quality of life.

Other common treatment options may include:

• Surgery – often the first step for tumours that can be removed completely, and sometimes curative if detected early

• Radiation Therapy – for cancers in difficult-to-reach areas; we may refer your dog to a specialist hospital for advanced treatments such as stereotactic radiation therapy (SRT)

• Immunotherapy and Cancer Vaccines – an exciting and evolving treatment area for certain cancer types

Quality of Life and Supportive Care

When making treatment decisions, we always prioritise your dog’s comfort and well-being. Our goal is not just to extend life, but to ensure that time is spent happily and comfortably.

At Allambie Vet, we are committed to supporting you throughout the entire process, helping you make informed choices and providing guidance with compassion and clarity.

Final Thoughts from Dr Alex

“A cancer diagnosis can feel overwhelming; however, it is not always the end of the road. With early intervention, appropriate treatment, and thoughtful care, many dogs continue to enjoy life with their families. If you notice any changes in your dog’s health or behaviour, please contact us as soon as possible. Early investigation gives us the best chance to help.

We are here to support you and your pet at every stage of the journey.”
