Possible causes:
* Normal postpartum changes: After giving birth, a dog's nipples may become swollen, red, and slightly crusty as they adjust to nursing. This is usually temporary and will clear up on its own.
* Milk leakage: If a dog has excessive milk production, it can leak and dry around the nipples, creating a crust.
* Infection: In some cases, crusting may be a sign of mastitis (inflammation of the mammary glands). Mastitis can be painful for the dog and requires veterinary treatment.
* Yeast infection: Yeast infections can also cause crusting around the nipples.
When to be concerned:
* Severe crusting: If the crusting is thick, hard, or covers a large area, it could be a sign of infection.
* Redness and swelling: These are also signs of infection or inflammation.
* Discharge: Any discharge from the nipples, especially if it's thick, yellow, or bloody, should be checked by a vet.
* Pain: If your dog seems uncomfortable or avoids being touched around her nipples, she may be in pain.
* Loss of appetite, lethargy, or fever: These are signs of a more serious health issue.
What to do:
* Monitor: If the crusting is mild and there are no other symptoms, you can monitor the situation for a few days.
* Keep it clean: Gently clean the area with warm water and a mild soap.
* Consult your vet: If you're concerned about the crusting, or if your dog shows any of the symptoms listed above, contact your veterinarian immediately.
Important note: Never try to treat mastitis or other infections at home. Only a veterinarian can diagnose the cause and recommend the appropriate treatment.
