So sorry your boy has been diagnosed with this horrible disease. I, sadly, have some experience with it. I've lost 2 dogs, a Dachshund and Yorkie to it and now my 14 year old Yorkie, Haley, was diagnosed with it a few months ago. It sounds like you're already seeking a second opinion so that's good. I work in a vet clinic and I can tell you with numbers as high as what your boy's are, the vets I work with would definitely recommend putting him on IV fluids to do a kidney flush. After the kidney values come down, they put them on sub q fluids at home. Keeping them hydrated is really important. Luckily with Haley, I caught hers early so I'm giving her fluids twice a week at home and so far she's doing well. As far as supplements, ask your vet about Azodyl. I had my last Yorkie on it and sub q fluids and he lived for a little over a year after being diagnosed. He also had severe arthritis and the medicine I had to keep him on to keep him comfortable for that was hard on his kidneys, so it's possible he would've lived even longer if not for that. The Azodyl has went up quite a bit in the last year so I'm trying something different with Haley. It's called Aventi KS powder and I just mix it in her food twice daily. I can get you the companies with cheapest prices if you're interested. I'm going to have her bloodwork repeated soon to see if it seems to be doing anything for her. She is also on Science Diet k/d food which is lower in protein and specifically for kidney disease. I hope this helps some. Good luck!
