This is gonna be a long one. But certain things need to be re-stated at this point and I want to answer Johnny's questions as best *I* can. I'm not a vet, but I love a dog who is an IMHA survivor.

I'm not OVERLY sure where the red blood cells are being destroyed. I can only assume that it is in the blood (not sure what you mean about adult cells). I'm still learning about this disease (new stuff everyday it seems). I say the blood because she is regenerating and the tests show reticulocytes and mixed RBC sizes.
Much depends on who has been overseeing the dog's care -- and usually at a university their "job #1" is to find out WHERE the blood is being destroyed. i.e., in the bloodstream or in the bone marrow. They do that by monitoring whether they *ever* see reticulocytes (baby red blood cells) in the blood or do they only see adults. Sounds like they're seeing baby red blood cells IN the blood from what you're saying.
Do you know what her average 'crit was before the disease?
(for those just joining us let me explain a bit: red blood cells aren't all identical. There are different sized ones which often equates to how old they are. Red blood cells are "born" in the bone marrow (and when they are babies is when they are termed "reticulocytes";) and then come out into the blood stream later.
a "hemoatocrit is a machine done test on the blood to see how many red blood cells there are per unit. Literally it's all done BY machine.
a PCV or "packed cell volume" is done by hand. They take a sample of the blood and it's put in a cetrifuge in a wee tiny tube and the blood will 'separate' into its components and they then measure the red portion of the blood against a chart and arrive at a "packed cell volume". IT IS THE SAME THING AS A HEMATACRIT -- except a PCV is done by human hand.
More chance of error? yes
HOWEVER -- a hematacrit will change depending on the machine used so there is always a "margin of error" for both.
from there the blood is also categorized into the various different types Johnny mentioned.
As far as the reduction in meds - it is all a great big huge puzzle, and yeah all sorts of things are "norm". Mostly because this is just NOT a disease where classic medicine really performs well. You just can't do a 'study' and say "well, 65% of those studied do well on X mg of ABC drug given bid."
Why? Because the other 35% may be dead ... or any one or 'few' of that 65% may walk across the room and throw an embolism and die before they walk out of the vet's office.
In this particular disease vets have to watch each individual animal SO carefully -- they look at the liver and kidney numbers in the blood work and try to guess which drug is likely to damage THIS dog the least and when is it safe to reduce a drug. And you GOTTA reduce them sometime because prolonged use of any of these drugs carries huge huge mega side effects -- many of which are life-threatening.
Ok -- so that being said ... what next?
First off, if you have Jean Dodds working on your dog, you have upped your odds right there. The lady KNOWS her stuff and blood is her life's work. And she's jumped into IMHA and the other auto-immune blood-related diseases (including cytopenia of all it's various forms) and has done incredibly helpful stuff. http://www.hemopet.com if anyone wants to look at her website.

I still wonder if 200mg/day is too much for a 36 pound dog.
It's a lot, particularly given that the dog is also on azathiaprene AND pred.
Johnny&Tessy
Tessy's HCT climbs really well until it gets to the high 20's. The first month of her treatment it climbed as high as 29 and stayed there for a few weeks till she had a relapse. (her HCT fell back down to 20...so I don't know for sure if this is considered a relapse or not)
Yeah, non-professionally speaking I'd say it was a mild relapse, but count your blessings because with THIS disease most animals that relapse, do it hard, fast and usually fatally. But often that relapse occurs after people have stopped the daily worry and have stopped getting the 'crit read at all frequently.
My husband and I developed our own set of "criteria" for how to read how Billy felt. for ME it was 999 "normal" behaviors and whether or not he continued them. For my husband (and later for me as well) it was simple. How hard is he wagging/aka "vibrating" that non-existent nubbin of a tail of his? THAT usually told the whole store in one easy to see "Hmm, he's not happy -- you feeling ok, buddy?" And we'd go racing to the e-vet or all the way up to Gainesville.
However -- that leads me to another discussion.
Relapse. Go back to a calendar and look HARD at it. What happened that day or a few days before? Had the dog been outside in public? To a dogpark or exposed to other dogs? (anything that could have caused the body to have to 'respond' to any sort of immune challenge).
How about emotional challenges? Some unexpected schedule change? any family upset? (someone got mad or upset, someone went away on vacation or back to school or ANY CHANGE in the emotional tenor of your home at all?? were YOU stressed at work?)
No, I'm not crazy -- my holistic vet was telling me the other day about a dog who came in with IMHA and the "change" was that it was a home of a single mom (dog was a shih tzu) and BOTH daughters went away to college at the same time. The one had taken a year off to earn money and they both went to college at the same time so they could room together. The dog literally was shattered at losing both girls at the same time. The dog began to RECOVER when the girls came home for a couple of weekends and gave the dog some attention!!
Next and probably most importantly -- toxins. Make a list. Check the calendar. Wreck your brain but think back to that week and just prior and think of what "chemicals" or unusual scents the dog may have come into contact with.
This could be as simple as a dose of heartworm preventive or Frontline. (no, it does NOT matter that the dog may have had ti umpteen times before -- they CAN become suddenly sensitive). It can be far more difficult to pin down -- things like:
was the dog recently groomed or boarded? (you have to consider pesticides used THERE as well)
Any sort of chemical pesticide -- like Frontline, Advantage, Advantix, ProMeris, ProHeart 6, 12 or whatever, Revolution, BioSpot, Interceptor, Sentinel, HeartGuard, anything with ivermectin, milbemycin or any known paraciticide.
Any sort of vaccine of ANY kind (bordatella, rabies, combo, individual)
Any sort of antibiotics or surgery. (there are some antibiotics that are far more apt to 'trigger' auto-immune diseases than others. AND these dogs who are already receiving treatment may also be breaking out with inflammation or diseases ***because*** they are taking immune suppressors -- my notes in the last thirty ... what, we're up to 36 now?? pages -- tells a lot about how nasty and awful Billy's skin was during the entire course of taking the steroids and steroild-like drugs. He was a sitting duck for infection of ANY sort and his middle-name was inflamed. You can't LET them be inflamed because inflammation of any sort **can and will** trigger a relapse. But you're darned if you do and darned if you don't because a major antibiotic change can ALSO trigger auto-immune. So you treat carefully and with nerves of steel every time. You use herbs where you possibly can (and even regular vets are learning the wisdom of this).
your yard being fertilized or pesticide being put out
you **neighbors** yard being fertilized or pesticide put out
your city/town, etc. being sprayed by air
did you change what you cleaned the floor with? new air freshener? new bathroom cleaner? new furniture?
Ok why the third degree? Because -- if you can nail down the cause or the "trigger" that started the disease (or the relapse) you can then have a FAR better chance of avoiding the problem in the future and of them getting off the drugs fully and being able to have a normal life.
True example (near as we can reconstruct) -- Billy got bitten by a tick. Yes, a darned tick. I found it on a Sunday morning ... it was embedded but didn't look like it had started to "swell". But it WAS embedded which means that's when tick disease is communicated. so I was watching for "tick disease". (In Florida ehrlichiosis and babesiosis are the two baddies here and I bet I screwed up the spelling on both of those).
BECAUSE I was watching for tick disease, I didn't hesitate to take him to the vet 6 weeks later when he was acting just a wee tiny bit "off". He wasn't jumping up on the water bed like normal -- almost like he was a bit "nauseated". We caught it EARLY. His pcv was 20. The vet was astonished because he was completely 'asymptomatic' (showing no symptoms). We had done a blood panel JUST BECAUSE I suggested it. It was 3 years ago the 3rd week of May. .
The vet started him on prednisone (that was Saturday) and we did another blood test about 10 days later and his PCV was 29. Great. But the vet decided to do a tick test with that because we didn't want IMHA and it COULD be tick disease and still be responding just to the prednisone... tick disease would be easier to treat and less dangerous. So it was sent it off Wednesday. The vet called me on Thursday and said "we've got a VERY faint positive ... like 'positive' on that tick test is 16 [to about 35] and Billy's is ... 16. So it's a light case if that's what it is."
At that point I would have done ANYTHING to have it NOT be IMHA. Sandra Slayton (and you'll see her posts on here) has been a friend of mine for YEARS ... long before we both gravitated to Dog dot com's board here. I knew her when she had Hunter. I knew what she went thru when she lost Hunter or IMHA/AIHA. I knew how bad this disease could be and how ***fast*** it could hit. I did NOT want it to be IMHA.
So we grabbed at the "positive" tick test and the vet called doxycycline in to Walgreens for me (he's 45 minutes away) which is the typical protocol for tick disease. Remember this is Thursday evening. I started him on the doxy at suppertime.
Friday night when David got home from work at 8, Billy went to go greet David and STAGGERED. We looked at each other and grabbed leash and purse and went to the emergency vet. The PCV taken Tuesday late in the day had been 29. Friday night it was EIGHT. Single digit. My dog was nearly dead. His "PCV" had fallen twenty-one points in just those 2 days.
That started our merry-go-round. In Billy's case he had SIX transfusions (5 up at the U of FL at Gainesville where he stayed in ICU the most of the next month - home on and off). As long as Billy was on the doxycycline he kept crashing over and over. He'd get a transfusion, feel better and come home in a few days, then it would bobble around 24-26 and then a few days later the tail would stop wagging and he'd be crashing and back to Gainesville we'd go.
During that time they determined Billy's body was killing the red blood cells in the bone marrow (he had a bone marrow aspirate) and it was killing ALL the reticulocytes before they got TO the bloodstream and it was continuing to kill adult red blood cells.
Along the way they did an entire complete tick 'panel' (it's several hundred dollars and it took nearly THREE WEEKS to come back). Billy did NOT have tick disease. He had apparently been 'recently exposed' and his body had formed anti-bodies and it was likely THAT was what triggered the IMHA.
His body saw the disease cells from the tick and formed antibodies to them to kill them/deal with them **as it should have**. BUT ... then for some reason Billy's body saw the antibodies **IT HAD FORMED** and decided that they, too, were invaders. Once all the antibodies had been killed the body further generalized and just kept killing other red blood cells.
The loosely held theory in Billy's case was the doxycycline - which is **often used** in veterinary medicine to BOOST a dog's immune system, simply threw his body into a frenzy to get rid of blood cells. ALL of them. It's entirely possible it was the doxy that actually threw him into full-blown IMHA. Because he was responding to the prednisone initially -- his PCV had gone from 20 to 29 in about 10 days. That's pretty darned good. It's possible his body literally went crazy with the immune "boosting' effect of the doxy and attacked the blood harder and faster. The guess is that the whole 21 points his blood fell happened in that one day on doxy.
But doxy is TYPICAL to give when you suspect tick disease when you have a dog who is anemic. My vets did NOTHING wrong. I must stress that.
*****BUT FOR BILLY -- DOXYCYCLINE WAS A TOXIC TRIGGER***** The tick bite was the initial problem ... what actually caused the body to react against that tick bite we'll never know other than the fact he was a mega allergy dog and it was HIGH allergy season. But it was the doxy, in Billy's case, that triggered his 'relapse'.
Most regular or "allopathic" vets never EVER look for a trigger beyond vaccines (and they've been slow to even acknowledge vax as auto-immune triggers).
Most vets don't bring it up -- in my own opinion much of that is because they just haven't been trained to think that way, and most of them don't even want to contemplate that something they gave they dog or sold could have caused a problem. Vets today have been taught to diagnose and treat disease, or fix a problem surgically. They have not been taught to think about "toxicity". It's just not something that regular vet school prepares them for.
Johnny, given that your dog has relapsed I would tell you to think until your brain comes loose to try to figure out WHAT may possibly have triggered both the initial onset AND the relapse.
A friend of mine on this board is fond of saying "Idiopathic" is simply that they don't know what causes it and it's a way of "avoiding saying". That's pretty darned true -- they really don't WANT to say what may or may not cause them.

I think I'm going to put her on it really soon. Her diet may be of concern a little. She eats chicken and green beens as a large part of her diet. She also gets white potatoe, liver, roast beef, fish sometimes, few teaspoons of pumpkin and a teaspoon of icecream 3 times a day to put her meds in. I give her a multi-vitamin with her dinner everyday also.
‘A couple of cautions here:
Chicken is SUPER **low** in iron – you can do much better with beef, lamb, particularly beef heart, liver, or whitefish (which is pretty high in iron actually). Chicken also – to quote the Chinese TCVM stuff tends to increase inflammation … not that it’s an “allergen” it simply tends to steer the body to inflammation. I hardly ever feed it at all. We tend to be hardwired as humans to think “chicken” because beef is higher in cholesterol. Dogs do NOT have cholesterol problems but there is so much more nutrition in beef, lamb, duck, whitefish than there is in chicken. Even turkey is better than chicken.
Vary the veggies – turnip greens, spinach, beet greens, kale and romaine – those are high in iron. The pumpkin is good – but so is sweet potato and squashes generally.
Ice cream – BE CAREFUL (and not for the reason you may think!!). dairy tends to make the body not absorb the cyclosoporine and you’re already concerned about the dose. You likely will be able to reduce it if the cyclosporine levels raise in the body and ice cream is going to work against you there.
What to use? Try braunschweiger (it’s in the cold meat section of the meat aisle). It’s “liver sausage” – already cooked. You just cut off a slice, and I slice those wheels into 1/6ths and then press the pill into the braunschweiger – the dog will LOVE it and it’s liver and *high in iron*.
Meat baby food also works (and you can use lamb, beef, veal – all high in iron). No ham – too salty and too full of nitrates.
