I came here looking for information for similar reasons. We have a puppy (an old English Sheepdog now 54lbs) named Hannah. She was born with Bilateral ectopic ureter and Bilateral kidney Dysplasia. She is also a picky eater. Her creatinine values were as high as 2.9 (she is eight months old) and average around 2.4. She has also experienced some significant GI issues, which now appear to be under control. We have since had a procedure done at UoP to (PENN Vet Hospital) to address the Bilateral ectopic ureter; between the procedure and Proin, that issue seems to be under control, and we reduced the dose of the Proin.
Now we have the picky eater and the Kidney issue to work with. This week, we started a new food that Penn suggested we try. Justfoodfordogs.com (I came here today to see if there was any other information). They have a specific Renal offering and will also create a custom food. Hannah has eaten with no coaxing, toppers, or peanut butter (dog version) at all.
Today, if successful, will be day three, and we just ordered two weeks’ worth and are hopeful we found something she likes.
Additionally, we began giving Hannah a medication called Azodyl. We used this with an aging girl several years ago, and it reversed her kidney disease; I shared the information with friends, and it worked for them. This is not something Penn has endorsed or has any reports on. My wife is a Dialysis nurse, and a friend in the field recommended it. this is the product: https://www.vetoquinolusa.com/products/azodyl. you can get it from 1800petmeds or other places. We will have Hannah checked in a month to see how well we are doing. I came here looking for some advice, and hopefully, I have given you something to consider for your family member.
Best Wishes
