Unfortunately, the kidneys were also failing (based upon the levels at most US labs but I don't have a reference for this lab). The only conditions that could cause a temporary condition are some sort of poisoning/leptospirosis infection and even then, the damage could be permanent. In an older pet, things like cancer become more of a concern but without being able to examine the pets and know the clinical history, it's hard to say. This could also be multi-organ failure which can result from many many causes. Based upon the physical exam, this poor pup sounds very very sick. Once the body temperature drops below normal, it's generally a poor prognosis. I hope this helps to answer your questions and please feel free to post any additional questions.
