My dog is desperately ill and I'm going to lose her soon

I took her in to have her teeth cleaned at 8 this morning. I got a call and the pre-op blood work showed anemia (28 when normal is 35-50) and repeat a few hours later showed it down to 14. I rushed her to the local ER and they suspect immune mediated hemolytic anemia. Basically, her immune system is destroying her red blood cells. She's staying over night and getting a blood transfusion and prednisone to suppress the immune system. I spoke with the ER vet and we agreed on DNR. Then I called back and asked that if she's dying to please let me come be with her at the end. I've been reading about IMHA and the prognosis is bleak; most dogs (26-70%) die within 6 months of diagnosis from pulmonary thrombosis or failure of medications to control the immune response.

This wasn't supposed to happen. She was supposed to come home with clean teeth and be a little dopey and we'd go to the off leash park tomorrow. She's only 5 years old! I cannot understand how a beautiful amazing pup like her is dying so freaking young!! She was supposed to be with me at least another 8 or 9 nine years!

I look around at my empty house and her toys and dishes and crate and cot and just can't stop crying. My 2 cats are old af and both have CKD and they're still hanging in at 17 years old. I love them to pieces but my pup was my go everywhere buddy.

I hope she can be made well enough to come home at least one more time. Even if I have to have her put to sleep in a few days or a few weeks, I want to be there with her at the end. I have always been there with my pets at the end. It's part of being a good pet owner and a decent human being.

Why does the universe hate me having a dog? My previous dog, a Lab-Rottie mix, got hemangiosarcoma when she was 11 so we had a lot of very good years together. This time I got a purebred with all manner of health testing and still this happens!
