My 7 year old female cocker has not been spayed. She has gone through heat quite a few times and now her nipples are hanging down as if she has had a litter of puppies and is breast feeding. She also gets these round hard nodules in her nipples right after she goes into heat and then they go away after a while or they leak with a brownish puss. Is this normal or should we be concerned? One vet at one point said that sometimes dogs that go through heat without ever having puppies sometimes have a false pregnancy and produce milk. Is this true and could that be why she is sagging and producing pussy substance?
This is not normal, she could develope mastitis or even worse a pymometra. I recommend spaying her at this point since she is too old to breed. vetcare P.S. every time she goes into heat it increases her chances of mammary cancer.
