Why is my dog's nipple suddenly swollen and feels hard?

This morning I noticed that one of my dog's nipples is suddenly swollen and feels quite hard to the touch. She hasn't seemed to act differently or be in any discomfort, but I'm concerned about what could be causing this change. Could this be an infection, or is there something else I should look out for?

Answer

Your dog's swollen nipple may be concerning, but there are several potential causes. It's important to observe any changes and assess whether a vet visit is necessary.

  • Monitor for signs of infection such as redness or discharge
  • Observe any changes in behavior or appetite
  • Consider hormonal changes, especially if your dog is intact

A swollen nipple in dogs can be due to various reasons, including hormonal changes, mastitis (an infection of the mammary glands), or even blocked milk ducts if your dog is a female who recently had puppies. Sometimes, the change might be benign, such as fatty tissue buildup or a benign tumor. Since many conditions share similar symptoms, tracking any progress while considering a consultation with a professional is crucial.
