My dog was diagnosed with a mass on the spleen. I went for a second opinion to a different veterinarian next thing I know the veterinarian is calling me to tell my dog collapsed and is intubated.I don’t understand what happened I walked him in the morning and had an appetite next thing I know my dog is dying.Is this possible how my dog died so sudden.

I'm sorry you are going through this with Snowflake now. This is possible if the mass on his spleen ruptured and caused severe internal bleeding. Without more information, it is difficult to say exactly what is happening, but splenic tumors can go very wrong very fast. Hopefully, Snowflake is getting the care he needs to bring him through this situation.
