I'm very sorry Karma has mammary tumors! The running eyes can be signs of an eye infection, and the vomiting can be a sign that the cancer has progressed. The vomiting can also be due to a GI illness, liver failure, kidney failure, pancreatitis, or eating something rotten among other causes. When a dog has vomited as many times as Karma has in such a short period of time, it's recommend to have the dog seen by a vet right away. In addition, any eye problems is also considered an emergency because the eye is such a delicate and important structure. My advice is to have her seen by a vet right away.
