first he is gorgeous!
Could he have ingested something? having a pancreatitis episode?
Hope they can figure out what's going on..
Masi had somewhat an episode like this a few months ago, ran every test under the sun, all coming back negative..after consulting with a specialist, we believe she ingested 'something' in the dirt (she's a dirt eater), slugged down some standing water that may have had bacteria or whatever in it..she was also vomiting, trying to vomit, and blood was pouring out of her butt
Stabilized her, whatever it was, went from her GI thru her blood stream into her lungs, causing pockets of "black" something or other..after 3 weeks of various treatments, she turned around.
Vets believe because it was 'spring', all these "things" were coming to life in ground/water, so could have been from something she ate.
He's gorgeous I hope they can figure out or atleast get under control what he's got going on.
