Dog mastitis home treatment: what to know

Mastitis is inflammation in breast tissue, often during breastfeeding when milk is not draining well or bacteria enter through irritated skin. The breast may feel tender, warm, swollen, or firm, and the skin can look red. Chills, fever, feeling unusually unwell, or pus-like discharge suggest that inflammation may be becoming an infection. A breast lump or focal area of firmness can have several causes, so do not squeeze it or assume it is mastitis without an examination.

For context, breast pain can occur with mastitis but also has other explanations. You can read more about [Breast Pain](/symptoms/breast-pain/) and [Painful Breastfeeding](/symptoms/painful-breastfeeding/).

Rest, drink to thirst, and continue gentle breastfeeding or milk expression if it is comfortable; abrupt stopping can increase milk stasis. Feed responsively and check that the baby is positioned and attached well. A cool pack wrapped in cloth may reduce swelling for short periods. Wear a supportive bra that does not compress one area, and avoid deep massage, vigorous pumping, tight clothing, and topical products that irritate broken skin.

These measures are supportive rather than a substitute for diagnosis. A clinician may recommend pain relief that fits breastfeeding and may prescribe antibiotics when bacterial infection is suspected. A lactation consultation can help identify latch, positioning, or milk-removal problems.

Arrange prompt medical advice if redness, pain, swelling, or a firm area is worsening, or if symptoms are not settling with supportive care. Seek urgent help for a high fever, shaking chills, faintness, confusion, rapid deterioration, or feeling severely ill. A soft, very painful swelling may indicate an abscess and should not be opened at home. Contact a clinician if a lump remains after inflammation improves, because persistent breast changes need direct assessment.

Ask: Could this be mastitis, a blocked duct, or an abscess? Is an examination or imaging needed? Which pain medicines are compatible with breastfeeding? Should I change feeding or expressing, and how can I protect milk supply while recovering? If antibiotics are prescribed, ask when improvement should begin and what to do if it does not.
