That doesn't make sense! Fresh fish has to smell, maybe if it really doesn't smell then rotten fish smell is what I relate with all fish when thinking in smelling terms. Anyways, it's still gross!
My dog had worms before, it was really gross because they (like 10 at a time) would be moving around while he was trying to poop them out... they'd still be moving for awhile after they hit the ground, too. Careful what you wish for!
