Cancer in dogs, the warning signs Cancer is a heart-breaking condition that affects too many people around the world. Unfortunately, it also impacts our beloved canine companions. As a dog owner, it’s very important to be aware of some of the signs of cancer in dogs – just as it’s essential to take heart from the fact that treatments for this disease are improving all the time. Let’s take a closer look… Cancer in dogs Unfortunately, cancer is one of the most common illnesses in dogs. 50% of all dogs over the age of 10 are expected to be diagnosed with some form of cancer. This means that recognizing the warning signs is even more important when you have an aging hound on your hands. By being vigilant, and providing age-appropriate exercise, a nutritious diet, and mental stimulation, you’re giving your dog the best shot at a long, active, and healthy life. The most common types of dog cancer Dogs and humans can actually develop the same forms of cancer. This list isn’t exhaustive, but it should give you a rough idea of the types of cancer that often affect our canine companions: Skin cancer Blood cancer Bone cancer Cancers of the immune system – such as lymphoma Abdominal cancers Cancer of the uterus Mammary (breast) cancer – mainly found in female dogs Testicular cancer Anal cancer The causes of canine cancer The causes of cancer are complex, and that applies to both humans and dogs. For this reason, there isn’t one definite cause. Cancer can be triggered by genetics, age, nutrition, and environmental factors. Fortunately, animal experts agree that canine cancer isn’t caused by things like bumps and scrapes. Here’s a look at some of the common causes of canine cancer: 1. Genetics As with humans, genes that cause cancer can be inherited. This means if your dog’s parents developed cancer, your dog is at higher risk. Certain dog breeds are also more generically prone to certain illnesses, including cancer. Golden Retrievers, Boxers, and Rottweilers are considered at higher risk of developing cancer (and specific types of cancer) than other breeds, 2. Carcinogens Carcinogens are harmful substances or features of the environment that can cause cancer. They include second-hand smoke, insecticides used in agriculture, certain viruses, air pollution, and UV rays from the sun. Researchers have found that sun exposure is a significant factor in developing squamous cell carcinoma, a cancerous tumor that can be seen in almost every single domesticated pet breed. Animals with white fur or markings are more likely to develop this form of cancer. 3. Age Sadly, cancer is one of the leading causes of death in dogs over the age of 10, with 50% of older dogs developing the disease and approximately one in four dogs passing from it. However, the reasons for this are largely speculated. 4. The environment In humans, most cancers are related to environmental factors. This can include their diet, their exposure to UV light and various chemicals, and more. The same is likely true for canine cancer, too. Reducing your dog’s exposure to environmental hazards – like smoke – is important in reducing their risk of developing cancer. What could help prevent your dog from getting cancer? One thing you could consider is spaying and neutering. Spaying or neutering your dog could prevent ovarian and testicular cancers from developing. Studies have also shown that spaying a female dog before her first or second heat may also help to reduce the risk of breast cancer developing. You should talk to your veterinarian about the best time for your dog to be spayed or neutered, according to their breed. Keeping your dog’s mouth clean and healthy may also reduce the risk of oral cancer. As well as trying to reduce your dog’s risk of cancer, you should educate yourself on the warning signs, so your veterinarian can catch and treat it early.
