How long does it take for a dog’s mastitis to heal?

A dog’s mastitis generally heals in about two weeks. Mastitis is usually accompanied by symptoms such as breast swelling, heat, increased nipple discharge, and red nipples, and requires antibiotic treatment.

If the condition is mild, keeping the breasts clean with local compresses and warm packs may let the dog recover on its own. If it is more serious, medication must be given promptly, and during recovery the breasts should be kept clean with strict diet management.
