Why does a female springer spaniel leak milk?

A female springer spaniel may leak milk due to hormonal changes associated with pregnancy or lactation. If she is pregnant, her body prepares for nursing, leading to milk production. Additionally, some females may experience milk leakage even when not nursing, especially if they are in heat or have had a recent false pregnancy. If the leakage is excessive or concerning, it’s advisable to consult a veterinarian.
