k9kidney@yahoogroups.com you will learn alot from that group. My friends yorkie has had 25% use of his kidney for 5 years and is going strong so it is not a death sentence.
I am assuming the creatinine was high as that is indicative of kidney disease not the bun bun is dehydration alone but if BOTH are high or creatinine is high that is more indicative of this so post the numbers - my demi had high bun on blood work but it was due to dehydration as her creatinine was fine
Did they do urinalysis as well as i would have urine checked as that is also more telling than blood work of what is going on
Low protein K/D diet is what they usually put them on - Getting them to drink alot of water is important as well and wet food is better than dry with dogs with kidney issues as it adds more moisture to their diet. My friend goes to a specialist in New York for her dog with Kidney disease and she believes dogs should eat more wet food than dry and kidney disease is big in cats and why cats who do not drink as much water as dogs should be on wet food as well. I have a friend who had a cat that died of kidney disease as well as dh brother's cat died of kidney disease so this is what vet relayed to them as well. Dh bro had to put water bowls in every room to entice cat to drink more water. I recommend changing water 3-4 times a day and use spring bottled water as it tastes better to them than tap - I know as my demi who had high bun is so picky she only drinks fresh water when we put it down otherwise she will not touch it so we have to change often and everytime we do she runs to the bowl and drinks a ton it is wild and yes she is very spoiled.
Hope this helps a little

I know another dog on one of our yahoo groups who is 15 and has lived with kidney disease for 9 years on a home cooked diet with a nutritionist so do not be too discouraged

and someone on here was real stressed about kidney issue when it was just the bun high not the creatinine and fyi when demi had high bun they freaked me out too and then i sent to jean dodds and she said she was just dehydrated and demi had a little protein in her free catch urine and she is fine so make sure it is creatinine and not bun as sometimes they can scare us for no reason

so hopefully this was the issue as it was with my demi
