Are you sure she's not pregnant? My first thought was a mammary tumor when you said it was hard (50% are benign and of the other 50% half of those have not spread and can be removed). After I saw your update of the milk, I'm thinking mastitis now. Mastitis can be treated with oral or injectable antibiotics if caught in time and is caused by bacteria entering the milk. Take her temperature, if she has a temp. then I would definitely suspect mastitis. |
