Ruby has cancer,​ Hemangiosarcoma.​ You can google it better than I can explain it. There is probably a tumor internal that will eventually burst and she will bleed to death.​
No cure, no idea how long she will last.​ She appears fine right now but a have noticed a few smaller spots on her belly.​ I am taking her to have stitches out next week so I may know more. She is not in pain.
I am devastated.

Here is a pic of her. Not sure if it will work or not.
