GRAPHIC but should be helpful -- If you think about what goes on, then the progression makes even more sense. When there is any sort of an obstruction, at first there's no reaction (unless it causes pain -- rarely). But -- depending on where the obstruction is -- that means that food can't move thru. So the poop that is already in the intestines will exit the body but nothing more. Food processed by the stomach will move INTO the intestines but can only go as far AS the obstruction.
So the dog may poop pretty soon after an obstruction but then stop. However, anything eaten post-obstruction will move from the stomach into the intestinal tract but that "fills up" (because nothing can exist).
USUSALLY about 6 - 36 hours after the obstruction occurred food will back up INTO the stomach. THEN you get the fiercest symptoms. Because the intestinal tract is 'full' to that point, food can no longer exit the stomach so ANYTHING eaten just sits in the gut with stomach acid pouring in. This quickly causes nausea and most anything put IN the stomach will be vomited and there is real stomach distress and the dog now feels horrible.
Blockages can be stellarly difficult to diagnose depending on what the material was that caused the blockage. Some things (like bits of fiber, natural things, etc.) don't show up on an x-ray -- and all you may see is the empty intestines but finding WHERE it is can be tricky. And if the blockage is near the stomach it can be really tough to locate it.
People tend not to think about the time factor -- and they expect the non-pooping to completely coincide with the nausea -- and that may not be the case.
Also -- be cautious trying to give any sort of oil or something to 'grease' the obstruction -- an obstruction can look very very like pancreatitis -- and pancreatitis can look like an obstruction. Many years ago my dog had what both my vet and I *thot* was a bone obstruction/injury (the dog was throwing up bloody ugly puke and having bloody diarreha). Earlier in the day the dog had injested some chicken bones (she found a KFC box on a walk and while my friend and I were trying to get a chicken bone out of HER dog's mouth, MY dog found what had previously been in the rest of the box but had been just thrown on the ground).
We thot it was an injury and a stuck chicken bone -- the vet told me to give her mineral oil as a 'first aid' type of gesture because he was so far from the vet clinic. Unwittingly I gave her the mineral oil -- except it was NOT a blockage at all!! It was pancreatitis (probably brought on by the greasy chicken skin) But the mineral oil made it WORSE.
Huskymom just watch for a couple of days. Frankly, I'd walk her on leash - it's a pain but you'll know what she passes. And make sure you know how much the dog has eaten. (GIGO -- what goes in has gotta come out)
