Is Expanding Polyurethane Glue (Gorilla Glue) Safe for Dogs?
Why it’s a problem
These glues contain diisocyanates that react with moisture and warmth, exactly what the stomach provides, so the foam expands many times its volume and hardens into a solid plug. Dogs are the classic victims because the glue smells sweet and a chewed bottle delivers a large dose. The resulting mass obstructs the stomach and does not dissolve or pass on its own.
How to keep your pet safe
Store glue bottles in closed cabinets or locked toolboxes, never loose in a backpack or on a garage shelf. Wipe up leaked puddles before a dog explores, and discard bloated old bottles safely.
Warning signs to watch for
Vomiting or repeated retching, swollen or hard belly, drooling, loss of appetite, lethargy, abdominal pain.
When to call the vet
Go to a veterinarian immediately and name the product so imaging happens fast. Do not induce vomiting and do not give food or water, because the swelling continues inside the stomach and endoscopy or surgery is often needed.
Common questions
My dog ate some Gorilla Glue two days ago and seems fine, is it over?
Not necessarily. The mass can take time to fully obstruct, and dogs sometimes stay quiet until the blockage is severe, so call a vet or pet poison hotline now; even late treatment matters.
How much Gorilla Glue is dangerous for a dog?
A surprisingly small amount can expand enough to block a stomach, so treat any swallowed quantity as an emergency. Do not wait to see whether symptoms develop.
