kalina82, I do believe that diet, lifestyle, age, breed, etc. can mean different "normal" ranges for different dogs. Dr. Dodds has extensive experience in this, and you could probably contact her for a consultation. You can send bloodwork directly to her for her to analyze, etc.
Or you could probably send her an email with questions. She's usually pretty good about answering them.
However, I have seen repeatedly the negative effects that meat proteins cause for
truly liver compromised dogs. I've seen it over and over again myself....
Dr. Center even explains how encephalogenic these proteins are for dogs with liver problems. They produce high amounts of ammonia that are not filtered in a liver that's not working properly and the ammonia enters the bloodstream and causes everything from inappetance to lethargy to seizures...This amount of ammonia causes unnecessary and hard work on the liver leading to damage.
Meat is not good for these kinds of dogs...It is not at all easy for their bodies to process when they have compromised livers. Also, compromised livers usually lead to compromised immune systems...
Dr. Center has done extensive research on nutritional management of dogs with liver disease. There are several articles by her that can be found online.
I'm not talking about your baby here...I'm just putting the info out there...
Hopefully some other raw feeders that have had bloodwork done on their dogs can post their results for you
