Why are my dog’s nipples swollen?

Swollen dog nipples can be caused by many things. First, red and swollen nipples may be a normal pregnancy response. Second, false pregnancy can also cause this, mainly from hormone imbalance, and the dog usually recovers gradually on its own.

In addition, conditions such as mastitis or mammary tumors also cause swollen nipples. In this case, take the dog to a veterinary hospital promptly for examination and targeted treatment based on the results.
