Signs of Dogs Having Cancer

If your dog has cancer, it will likely show a few signs related to the disease. However, because of the stoic nature of canines, your dog will likely try to hide any indication that it doesn't feel well. Dogs often experience the same symptoms of cancer that humans do and knowing what to look for could potentially save your four-legged friend's life.

  1. Tumors

    • Just like in humans, tumor are often a sign a dog has cancer, according to the Pet Place website. If you notice a lump anywhere on the dog, have a veterinarian evaluate it. Not all lumps are cancerous; however, it is always better to have a vet examine it and test it for cancer than assume it is benign. Lumps in the testicles, mammary area or abdomen could be a cause for concern, as are sores that don't heal and lumps that increase in size. In addition, swellings or lameness in bones could be signs of tumors.

    Changes in Behavior

    • Dogs with cancer often do not feel well; therefore, if you notice your pet is acting abnormally, take it to a veterinarian for a physical examination, suggests the WebMD website. Cancer doesn't always show significant signs early on, so it is important to bring any concern to the vet's attention as soon as it occurs. Dogs with cancer will commonly stop eating or refuse to participate in activities they normally enjoy. In addition, the dog may act depressed or seem more lethargic than usual.

    Physical Abnormalities

    • According to the Pet Place website, dogs with cancer will commonly develop physical abnormalities. For instance, a dog with cancer may experience unexplained bleeding from openings in its body. The dog could also have issues urinating or defecating or develop changes in its bowel or bladder habits. The dog may have difficulty breathing or have a foul odor coming from its body. Problems eating or swallowing could also be symptoms of cancer in a dog, as are persistent limping, fevers and loss of stamina, suggests the Animal Hospitals USA website. Because many of these symptoms could pertain to a variety of illnesses, it is essential to have your dog evaluated by a veterinarian to look for cancer.
