The lump or tumour that is not causing any pain or discomfort to your pet could be simple lipomas to benign tumours. If you notice this lump growing in size or inflamed with pain or discoloured skin, etc requires immediate attention. Problems like lipoma may not cause any harm while abscess or cyst, panniculitis or cancer require medical attention. It is best to seek your vets advice ASAP.
