Re: Lost a great dog on Christmas Eve....am stumped
First I'm very sorry for your loss. I'm not a vet but do work with them on occasion doing natural therapies on animals so I get to see a lot of stuff, and I doubt you'll get a definitive answer on this one. However it does sound neurological/brain with his muscles and sensations shutting down etc.There are multiple possibilities whether it was a genetic defect, brain inflammation, brain tumor, aneurysm, virus and so forth. The excess salivation can go along with convulsive disorders like seizures. The brain stem also controls temperature regulation/fever. However the fever could have been his immune system ramping up in response to something. You didn't let him suffer which was the hardest and best thing to do under the circumstances if there was no chance for recovery. Sounds like you gave him a good life short as it was.
