Sorry to hear this. My heart goes out to you. Hope he pulls through ok.Bear is at the vet. I came out of the fish room where I was busy this morning and petted him and he was really sick.
So we went to the vet.
Splenic tumor that has ruptured (maybe, hard to tell on ultrasound) with blood in the abdomen. They are going to remove his spleen. Surgery after the animal on the table now is finished and they clean up.
That's where we are now anyway. I told them to fix what they can but no heroic measures when asked. I am not sure what that even means with a 110 pound dog.
I may start drinking heavily. Or something.
