What could be wrong with my female Labrador Retriever?
To my knowledge, she isn't pregnant - but that's just the problem. She's four years old, five in mid-December. She usually stays inside, backyard is fenced in, male schnoodle was fixed when we got him. Hasn't been in-heat in about two months. Some one in my family squeezed one of her nipples, and said blood came out. We squeezed some more, a little blood came out of some, a little milk (or some other white liquid) came out of the others (some seemed to be a mixture). Should I be concerned? What could be wrong with her? Give me as much info as you can, please. I don't have the money for a vet (so that is a last resort).
