Just adding that she was on 3 full days of fluids at the ER after her crisis
I just wanted to chime in on my experience and what is working. Tony is correct about the phosphorus. My dog had an Addisonian crisis and acute kidney failure mid Nov 2016. 3 full days at the ER and all numbers were normal except an elevated BUN. It only took about a week before she started acting tired and became finicky eating. Back to the vet's, and all her numbers were elevated including her phosphorus...8.8. They actually put her on 3 more days of IV fluids....so that's another option. The fluids brought her numbers back to normal, except the BUN. I was sent home with lactated ringers, K/d diet, and aluminum hydroxide (phosphorus binder). I know it's expensive, but can you ask to have your dog put back on IV fluids?
Hello. Welcome to our group of friends, although I'm sorry there's a need for you to be here.
A few questions ...
Has Lucy had any IV Fluids? While SubQ fluid is a good primary treatment, helping get creatinine down, it take much longer than IVs and isn't quite as effective. So, if you stay with SubQs, it could take quite a while to see any great improvement. Also what type of fluid is being given? The ideal would be lactated ringer.
While talking about fluids, what weight is your dog? The dosage is crucial and it depends on the weight of your dog as to how much can and should be given.
Mirtazipine is a favorite medicine of mine that I recommend often, and I do believe it helps a huge amount. Cerenia is good alongside it to help with anti-nausea. I haven't heard of Damestron? Can you check the name again. Do you know what it is being given for?
TUMS are okay, but do be careful of adding too much calcium - they are beneficial, as long as calcium blood levels don't climb high. The calcium will also help keep phosphorous under control - which is a crucial thing - but if both calcium and/or phosphorous blood levels start climbing, it would be better to add an alternative phosphate binder to the medicine regime. If this happens, please ask me about it. Monthly blood checks are important at this stage of management, so you and the vet knows what's changing and when.
You didn't actually list phosphorous levels in the bloods. Can you let me know if it has been recently tested and what the level is.
Helpful supplements you might consider include pure organic salmon oil (rich in omega-3 fatty acids), rhemania-8, CoQ10 - these can be given in rotation, so salmon oil (with a Vitamin E canine capsule, as salmon oil depletes this vitamin in the canine body) on day one, then rehamania-8 on day 2; then CoQ10 day three. These help boost the kidneys, improve the immune system and reduce inflammation. All quite helpful.
In terms of eating, I'm hoping the Mirtazipine helps encourage Lucy's independent eating over the next week or so - it would also be helpful to increase the frequency of "meals", so up to about 6 meals a day, with 2hrs or so between meals. This reduces stress on the kidneys (dealing with smaller volumes of food being processed) and reduces the volume of toxins released into the bloodstream caused by metabolization.
Hope this helps.
Get back when you can.
Tony
So sorry that you are going through this :/ I don't have a lot of advice, as I'm pretty new on this kidney disease journey myself, but just wanted to let you know that you're not alone. My dog Spirit was diagnosed in October, though she seems to be crisscrossing between Stage 2 and Stage 3. Tony will probably chime in soon, though, and he has a lot of advice.
