My pal LL knows a lot about kidney problems in animals as her cat suffered … she provides additional information in the post below for those with elderly cats and dogs. I hope she doesn’t mind me posting her response verbatim but her knowledge may be helpful to others with geriatric pets. So far my attempts to change e-dogs diet to what is recommended have not been successful but I can supplement her diet with iron/B vitamin elixir that LL notes!
from LL:
I was just checking out your blog, which I do from time to time, and I saw your entry about poor old Ella. I was interested to see your kidney research. Emma (LL’s cat) had kidney disease, and ended up dying from complications due to kidney failure. I treated it for two years, though, with all the things your research listed. It seems all old animals end up getting kidney failure. A heavy-handed way to deal with it is to administer subcutaneous fluids (saline solution through an IV bag, but administered just under the skin between the shoulder blades) to keep the animal well hydrated. This flushes the kidneys and brings the BUN (blood urea nitrogen) and creatinine down, making animal feel better because the toxins aren’t building up in their blood. (I did this every other day for two years with Emma, because she was young and otherwise healthy and happy.) You can and should give them extra Vitamin B and a low protein diet. Kidney function affects the production of the hormone that makes the body produce red blood cells, so animals with kidney failure are often anemic or borderline anemic. You can help by giving iron and B12 vitamins. There’s a good animal iron-and-B vitamin supplement called Pet Tinic. It was easy and effective. If things are dire and the animal is severely anemic, you can give them Epogen, which is a hormone made from a human blood product. It’s a bit risky with animals, and it’s a last-resort treatment, way on down the line. (Yes, I tried it. It also costs about $100 per needle.)
I’m not sure whether you’re considering treating Ella’s (likely) kidney failure, but there are a few things you can do to mitigate it a bit: low-protein food; encouraging her to drink more water; B vitamins; iron if her blood is anemic. If you know for sure her BUN, creatinine and phosphorus levels are high, you can put "phosphorus binders" in her food, so the phosphorus from the food doesn’t get absorbed by her body. Phosphorus binders are cheap, and are sold under brand names Renalgel and a couple others (liquid and powder), for people on dialysis. High phosphorus will make the animal feel more nauseated and will worsen kidney failure, so it’s important to keep it under control. Animals with kidney failure also often have LOW potassium. Again, you need the blood test to be sure, but you can treat it with Tumil-K, a potassium supplement that goes in food. Symptoms of low blood potassium include weakness in the back legs and hind end. (THIS IS VERY HELPFUL AS THIS IS WHAT E-DOG APPEARS TO HAVE - RATHER THAN DYSPLASIA WHICH IS PAINFUL).
I found that all of the food/vitamin supplements really helped Emma, and they were fairly easy to administer.
I went the full route with treatment for kidney failure, so if you ever want to talk about palliative care for animals….. Our other cats, Thumper and White Nose, also ended up having failing kidneys when they were very old. I did not go the full treatment route with them, but I gave them some food supplements.
Oy vey. I don’t envy you having a geriatric dog. It’s hard to see them go downhill. I have a houseful of young cats again (except Martha, who is about 9), and they are full of beans. Little Gamina got her cone off finally, and is completely healed from her spaying. I discovered the other day that she loves to eat cantaloupe. She goes wild for it. Weird.
Anyhow, I wish you the best of luck with Ella. You may be able to help her a bit in the short term with some easy diet changes and supplements. You’re right about the vet visits, though: once you go, you get on the medical rollercoaster of blood tests and more blood tests, possible Xrays and ultrasounds, etc. (unless your vet is sensible enough to see that you need palliative care, not a stressful treatment regimen.) I did all that only because Emma was 10 when her kidneys failed, when she should have lived to be about 18.
Me: As E-dog is geriatric (at 15.6, at least, in human years), I only want to make her comfortable. I am in denial, and comfortably so, most days. She has a bunch of lumps - I prefer to think of them as fat deposits - but as soon as she goes to the vet., biopsies will be recommended. And then there is the pressure of not following recommendations in terms of possible treatment. I know LL did much research on this issue and I am fortunate to benefit from her experience. I will try to implement the dietary measures that might help old e-dog. Despite the indications of kidney weakness, some days she is really perky. At other times, she appears to be off in her own e-world, which could be called dog dementia! But thanks a bunch LL! I have no problem with trying to supplement her diet and you provide lots of valuable information that would take me eons to research and as I am in denial … would I?
