Spleen Cancer In Dogs Symptoms: What Are The Warning Signs?

Spleen cancer in dogs is a malignant tumor that develops in the spleen. This type of tumor can develop slowly and some dogs may display non-specific (general) symptoms or none at all during the early stages.

Specific Spleen Cancer in Dogs Symptoms

When there is blood loss, dogs may show the following symptoms:

  • distended abdomen
  • weakness
  • pale gums
  • difficulty breathing
  • anemia
  • collapse

As a pet owner, you should be aware of the above canine spleen cancer symptoms or any changes in your dog’s health and behaviour. If the tumor is detected early, the spleen can be removed before the tumor ruptures and bleeds.

Canine spleen cancer, especially splenic hemangiosarcoma, is highly aggressive and tends to spread quickly to other organs. Early detection and treatment with surgery and chemotherapy may prolong survival times.
