Yes, X-rays (radiographs) can show signs of intestinal blockage in dogs, revealing gas/fluid buildup or visible objects like bone/metal, but soft items (fabric, plastic) might be missed, requiring ultrasound or contrast studies for definitive diagnosis, though surgery might be needed even with suspicion. Veterinarians look for dilated intestines and compare views, but sometimes repeat imaging or surgery is necessary to confirm a blockage, as X-rays aren't always conclusive for all materials, say Cornell University College of Veterinary Medicine, Rural Animal Clinic, and Petco.

What is the 3 6 9 rule for intestinal obstruction?

The 3-6-9 rule is a mnemonic for identifying bowel dilation on imaging (X-ray/CT) in suspected intestinal obstruction, stating normal bowel diameters are typically <3 cm for the small bowel, <6 cm for the colon, and <9 cm for the cecum, with values exceeding these suggesting obstruction or ileus. A related rule notes high rupture risk at >6cm (small bowel) and >9cm (colon), with the cecum >12cm being critical. This rule helps radiologists spot dilated loops and differentiate obstruction from paralytic ileus, often seeing more colon gas in ileus and more small bowel gas in obstruction, plus late signs like no rectal air.
 

What are the four cardinal signs of small bowel obstruction?
