Hello, this is Dr. Jess. I am so sorry to hear about your dog. How horrible to lose her so quickly and unexpectedly. When I read your description, the first thing it made me think of was a severe case of pancreatitis. Oftentimes we don' t know what incites a case of pancreatitis. Occasionally we can see it after a pet eats something very high in fat, but not always. The most common symptoms are vomiting and abdominal pain (which can cause panting). In severe cases of pancreatitis we can see very high fever, low blood sugar, severe weakness, and a condition called DIC, where we can see bleeding as well as clotting develop throughout the body. Here is an article on this disease: http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=2214
I have seen cases that present very similar to your dog. A dog that had severe vomiting, came in to the clinic very weak, with low blood sugar and fever, who ended up dying shortly after presentation.
