Sorry to hear about your Husky. It is hard to watch on of our fur babies ill and feel that what we are doing is not helping.
(I've not posted at the coconut oil forum before though I've been reading for awhile)
Did your vet say whether your dog was checked for Giardia or Coccidia when they did the fecal? Reason that I am asking is that the symptoms you list sounds like one of those parasites.
It is sometimes very difficult to see signs of these two parasites when looking at the fecal slide under the scope. I was a vet tech for awhile and had to look for these!
If you can get another stool sample to your vet to check (fresh is best!) then perhaps they could concentrate on this (that is if they know for certain your Husky is free from Giardia and Coccidia).
I was reading here earlier and read that coconut oil does help in killing of Giardia.
I am on humaworm's parasite cleanse right now. I wormed my dogs and cats at the same time. One of my cats got out and had the same symptoms as what your dog has. After giving her the pet wormer I purchased at humaworm her symptoms cleared up and she is much better. Her appetite came back, stools are normal, she is gaining weight (she lost from 5lbs to almost 3lbs). Humaworm does work at killing these parasites...
