What half a tube means for a 7 kg dog
This quantity is catastrophic at this body weight. Polyurethane glue expands 3-4 times its original volume—half a tube could create a mass larger than your dog's stomach capacity. Unlike gradual poisonings, the physical blockage from this much glue will cause acute distress within the hour as digestive functions halt.
The glue is already reacting with stomach fluids as you read this. At 20 minutes post-ingestion, some expansion has occurred but the mass may still be retrievable via endoscopy if you act now. Every additional minute decreases that possibility and increases surgical likelihood. Transport your dog carefully—sudden movements could displace the forming mass dangerously.
Why vomiting is dangerously ineffective here
Standard first aid for toxins fails catastrophically with expanding glues. Induced vomiting risks the glue foam blocking the esophagus or trachea during expulsion—a life-threatening airway emergency. Even if partially expelled, remaining glue continues expanding inside, now with added irritation from retching.
Similarly, don't offer water or food in hopes of 'diluting' the glue—this accelerates the chemical reaction. Your vet team will manage hydration intravenously once the glue is addressed. Focus solely on safe, rapid transport to the nearest surgical-capable clinic with your dog's head elevated to slow the glue's descent.
The progression from ingestion to obstruction
Between 30-90 minutes post-consumption, the glue transforms from liquid to spongy foam, then hardens into a rigid mass. At half-tube volume, this will likely fill the stomach entirely, blocking both entry and exit points. Pressure builds as digestive secretions accumulate behind the blockage, risking stomach rupture.
Early signs include sudden lethargy as blood flow redirects to the distressed digestive system. You might hear hollow sounds from the abdomen as normal gut movements stop. These aren't just warning signs—they're evidence the obstruction is already developing. Immediate imaging confirms the mass size and location.
Surgical versus endoscopic intervention options
Your dog's best chance depends on arrival time. Within the first hour, vets may attempt endoscopic removal using special retrieval tools—but only if the glue hasn't fully expanded. After that window, laparotomy (abdominal surgery) becomes necessary to physically extract the hardened mass and assess any tissue damage.
Bring the glue tube's packaging—knowing the exact formulation helps surgeons predict expansion completion time. Post-op care typically includes IV fluids, gut protectants, and monitoring for secondary complications like peritonitis. Survival rates drop significantly after 2 hours, making your current timeframe critical.
