My dog has several yellow bumps on his chest
Expert Answer
If a dog develops several yellow bumps on the chest, possible causes include: 1. Nipples—every dog has a few pairs of symmetrical nipples on the chest and belly that look like small beans; this is normal anatomy.
2. Seborrheic dermatitis—a common skin disease marked by yellow or yellowish-brown oily scales and papules, often tied to overactive oil glands and possibly follicle blockage and bacterial infection. Yellow bumps can be a symptom.
3. Pustular skin disease—a skin infection with yellow pustules, usually from bacteria, causing inflammation and pus. 4. Lipoma—a common, usually benign subcutaneous lump that is yellow or tan, soft, and movable under the skin.
Because your description is limited, take the dog to a vet for a professional exam and diagnosis; the vet can determine the cause through observation, physical exam, and necessary tests, then plan treatment.
