Diagnosed last week need help

My Cookie has been diagnosed with this dreadful disease. She’s a 6 yr old terrier mix, spayed and up on all vaccinations. Her last ‘normal’ day was this past Monday, Tuesday she wouldn’t fetch and had a little loose poop and no appetite. Wednesday I went home on my lunch hour and let her out to potty, she did something she never does, she squatted right in front of me and I saw the heavy tint of blood in her urine. We went to the vet immediately. He did the CBC (RBC was 23) and other tests for parasites (neg) her tongue and gums were very pale, her heart was beating crazy and she has a murmur. He told me that Cookie had an auto immune problem. He knew she was in serious trouble so he kept her overnight to administer meds and check her blood again in the am just in case she needed a transfusion. Thursday am her RBC was 27, a small improvement but we were hopeful she was on the mend. They sent us home with prednisone 30mg and doxicycline 300mg both 2xs daily. The vet was going to be out of town until Monday so he made sure to give me all the notes and test results in case we had to take her to an emergency clinic. Friday there was no improvement, she was just existing. I was hand feeding her and getting more worried by the minute.
I live in a very small town in N. Florida and my vet is just 3-4 years out of college so I’m not sure he had ever had a patient with the disease. It’s probably good fortune he was out of town a few days because on Friday we decided to take her to an emergency hospital an hour away in a much larger city. I just wanted peace of mind that she was improving. I called the hospital and talked with the doctor. They call our vet and had them fax all the information on Cookie to them. At the clinic the doctor explained the details of this AWFUL disease. Her test showed RBC at 34 and very good baby RB production. She prescribed and a complete treatment plan that included Sucralfate dissolved, 10mg Pepcid 2x day and an RX for cyclosporine 60 mg 2x day. She gave the RX but said it was just in case she needed it so we didn’t fill it.
Monday 9/25/17 Cookie was not getting better we went back to our local vet RBC at 17, So we start the cyclosporine. Wednesday RBC at 20, improvement but Cookie is still very sick, has spurts of perkiness then bottoms out.
Her appetite has not been good since she got sick but no vomiting until this morning. I started the GI protection at 6 and she was hungry so I made her wait about 15 minutes. I know I’m suppose to wait an hour but she’s so weak I don’t want to miss an opportunity when she’s hungry. I gave her all other meds at 7:15, Pred and Doxy are pills, Cyclo is liquid. At 10am she vomited all her food from this morning. So now I’m worried that the Pred and Cyclo didn’t absorb but my vet said it probalby did in that amount of time.
We go back tomorrow for RBC count.
I’m going to upload her records. Will you please look at them and tell me what you think? My Cookie is so sick and she is usually the happiest, energetic little pup. My husband likes to tell people how she can jump up and knock his shade off his nose. I’m really worried. Thank you for what you do.
