“Every lump, bump or skin change should be checked,” says Dr. Zaidel. “It could be benign or cancerous, but it’s always easier to treat the earlier it’s caught.” Feel for bumps, lumps or swelling as you pet your pooch. If you notice something iffy, don’t delay – there’s no way to distinguish between a lump that’s benign or malignant without taking a sample. Also, pay attention to any sores that won’t heal or lesions that seem itchy or painful.
