Beware of canine Gorilla Glue ingestions.

Household adhesive ingestions are considered relatively non-toxic. Gorilla Glue is a household glue containing a urethane polymer and a polymeric isocyanate liquid compound available in container sizes of 2 to 36 oz, and when applied will expand to 3-4 times its original volume. We report the ingestion of Gorilla Glue by 2 dogs that caused obstructive masses requiring surgical intervention. Dogs with a history of Gorilla Glue ingestion should be monitored closely by their owners and a veterinary referral made if signs of gastrointestinal distress develop.
