Are certain dog breeds more prone to the disease?

The answer to this is yes – in fact Golden Retrievers, Boxer dogs, Bernese Mountain dogs and Greyhounds are predisposed to developing the condition.

What is cancer and how can I spot the symptoms in my dog

Just like in humans the disease is caused by abnormal cell growth. Normal cells in humans and in dogs will grow, divide and then die (this is normal). However cancer cells will grow, divide and continue producing abnormal cells.

Cancer in dogs will also develop due to problems associated with the DNA within your dog – this might be because your dog has inherited damaged DNA or because something else has caused damage to the DNA i.e. foreign pesticides, smoke or something else.

This disease comes in two forms – benign (this is when it is slow growing and can be surgically removed) and malignant (this is when the disease is aggressive and will spread quickly throughout your dogs body). The mailigant form of the disease will normally start in one place (so if it started in the Liver it would be called Liver Cancer regardless of where it spreads).

Your dog might develop cancerous tumors that start to affect normal tissue – these growths will possibly start to affect other parts of the body too – when normal tissue is replaced by a cancerous tumor it is referred to as metastasis. Non-cancerous can also develop (benign tumours) but these will affect one area and will not spread – this is referred to as metastasize.

What are the symptoms of cancer in dogs

The symptoms of the disease will vary depending on the type of cancer that your dog develops. However some of the symptoms that you might notice in your dog can include…

  1. Watch out for any unusual lumps and bumps that appear – you should always get any lump checked out by your vet to get an accurate diagnosis. You should watch out for any changes to a lump that your dog already has.
  2. Your dog might lose his appetite and appear lethargic with little energy.
  3. Your dog might struggle to poop – if he does defecate the stools might be long and thin.
  4. A runny nose (especially if blood is present) can be a symptom of cancer in dogs.
  5. Take a look at your dog’s mouth (inside), look out for any teeth that are loose or appear to have moved. Your dog’s breath might also be particularly unpleasant. Your dog might also drool excessively.
  6. Diarrhea and vomiting can also be a symptom of cancer in dogs (and a symptom of other problems).
  7. Your dog might need to drink more water and urinate more often. Another symptom of cancer in dogs is a difficulty when your dog try’s to urinate – there might also be blood in the urine.
  8. Your dog might also have fluid draining from the ears. The ears might also smell particularly bad.
  9. Your dog might also have difficulty when walking or appear to limp.
  10. Watch out for behavior changes – you know your dog best so if you have any concerns about your dog’s health take him or her to the vet.

  3. Herbicides (also known as weed killer can not only damage weeds it can possibly lead to cancer). Pesticides and insecticides can also cause the disease.
