- LumpsNot all lumps and bumps are cancerous in dogs. There are sebaceous cysts, lipomas, and warts all of which are benign but if you detect a growth on your dog it’s important to have it checked out by a veterinarian and if warranted, aspirated and biopsied.
- LesionsScratches and abscesses are not uncommon for the normal, active dog but the sores that don’t heal can be of concern.
- LamenessBone cancer is typically found in larger breed dogs like Great Danes, Bernese Mountain dogs, Rottweilers, Boxers, Newfoundlands, Saint Bernards, and Great Pyrenees and the primary early indication is prolonged limping or favoring a limb or side. Other types of cancers can also cause persistent lameness.
- Appetite LossIf your dog shows no interest in eating or their daily consumption has declined for several days, take them to a vet.
- LethargyTiring out easily, unwillingness to exercise and loss of interest in normal daily activities can be an early sign of cancer.
- Weight LossNot to be confused with loss of appetite. Cachexia, or emaciation, is often associated with cancer and can occur even if your dog is still eating normally. So if your dog is inexplicably losing weight, consult a veterinarian.
- Loud OdorA very strong and offensive smell can sometimes be a byproduct of tumors in the mouth and nasal cavity.
- Loss of Normal Body FunctionsDogs having difficulty voiding or defecation or unusual urine or feces should be looked at.
- Bleeding or Bloody DischargeBlood present in vomit, stool, and nasal discharge are cause for serious concern and although not always telltale signs of cancer, your dog should be examined as soon as possible.
- Labored BreathingAbnormal respiration or respiratory distress can be a symptom of cancers in dogs.
