Hello. I'm sorry for the long wait.
It sounds like it's probably an obstruction. If it had the look of cloth, then it may be a sock or underwear or part of a toy. Those are the more common foreign bodies that we remove from dog's intestines.
For right now, I would just have some water out in case he wants to drink. I would not try to give any food, as that may induce more vomiting and pressure on the obstructed intestine.
In the morning, they'll re-shoot x-rays. If the cloth looking thing is still in the same place in the intestine, then it's off to surgery. I don't see a need for ultrasound at this point. At surgery, we can usually just make an incision into the intestine and remove the foreign body. We then close it up and keep them for 1-2 days to monitor and keep on IV fluids. Once eating, they go home.
I hope this helps, let me know if you have any other questions.
I would actually go with x-rays of ultrasound. Ultrasound is not very sensitive for picking up foreign bodies. If the x-ray pattern on the 2nd films is not much different than the 1st, then I would just go to surgery. Ultrasound is more sensitive for picking up masses in the kidneys, liver and spleen. It's also good for picking up intestinal wall thickness. I find it pretty difficult to find foreign bodies with ultrasound.
Yes, the 2nd x-ray is to see if the intestinal loops are moving or if they're getting more dilated with gas or fluid. If they're not moving and they're just getting more dilated, then that is evidence of an obstruction. Remember, an x-ray is just a snapshot picture in time. Having 2 x-rays a few hours apart tells us much more about whether or not those intestines are moving or obstructed.
