Yes, I would be worried about Loca. In a senior dog, a large lump could potentially be a malignant tumor. Bloody nipples are also not normal, and she could have hurt herself or may have mammary tumors causing the bloody nipples. Best thing to do is have her seen by a vet in the morning. The vet can diagnose what is causing the lump and bloody nipples, and can discuss treatment options with you. Good luck, I hope this helps!
