10 Biggest Early Warning Signs of Cancer in Dogs

7. Non-Healing Wounds: A Sign of Something More

Wounds or sores that do not heal within a reasonable timeframe can be a sign of cancer. The body's inability to repair itself may indicate an underlying issue, such as a tumor interfering with the healing process. Non-healing wounds can be associated with skin cancers or other malignancies that affect tissue repair. Regularly inspecting your dog's skin for wounds and monitoring their healing progress is important. If a wound does not show signs of improvement, veterinary evaluation is necessary. A biopsy may be required to determine if cancer is present and to establish an effective treatment plan.
