Subject: GORILLA GLUE A HUGE DANGER FOR DOGS!
Date: Sat, 14 Apr 2007 09:03:18 -0700

THIS IS SOMETHING I THINK ALL DOGGY PEOPLE NEED TO KNOW ----

Yesterday, my 35 pound Terrier mix had a HUGE mass of Gorilla Glue
removed from his stomach. It took a 12" incision to get the job done
and he's going to take a long time to recover, if indeed he makes it.

Gorilla Glue has 2 very dangerous properties:

1. its smell & taste are attractive to at least dogs

2. when ingested, it oxidizes, just as it does when exposed to air,
and expands greatly in volume. Internally, a very small amount will
expand many times over and continues to harden.

My dog sought out the container (a 4 oz size), having to essentially
climb up on a table to reach it. Hours later, I found the chewed
container & figured it was too late to have his stomach pumped, so
just kept close watch on him. It didn't appear that he had eaten very
much, or any, of it.

Now, I know better! Had I known that the stuff would continue to
expand and harden, he would have been at the vet's immediately, even
if it were an after-hours call.

Seems like any dog who gets a hold of this stuff should have a stomach
pump asap, or emergency surgery if pumping won't do the job.

SINCE THE CONTAINER GIVES NO INFORMATION ABOUT EITHER THE
ATTRACTIVENESS TO DOGS OR THE EXPANSION FACTOR, TREAT THIS STUFF AS
THOUGH IT WILL KILL YOUR DOG (or goat or horse or sheep or bunny or
cow or ....) IF IT GETS A HOLD OF IT!

A company representative, when contacted by my vet, seemed unconcerned
about any responsibility on the part of the company. Of course, they
could no doubt change the formulation to make it repugnant to dogs.
If that's impossible, prominent labeling of its properties & the
danger to animals is then mandatory.

Pass this on to others you know who have pets, especially dogs. Had I
known what could happen, this stuff would have been out of my dogs'
reach! There are some other stories on the Web........

Since this product is popular, and increasingly so, I think letters to
the company might get them to make changes in formulation &/or
labeling. Of course, a lawsuit would really get their attention!

Meantime, treat this stuff the way you would poisoned rodent bait!

On their website it DOES state that it's dangerous for children and pets.  I would presume it's on the label as well which, was pointed out to me on the other site I posted this information on.

Here's a article from the ASPCA regarding these types of glue.

An Expanding Problem: Pets Ingesting Polyurethane Glue is on the Rise

309% Increase in Expanding Glue Cases Since 2002

ASPCA Media Contacts

FOR IMMEDIATE RELEASE

Urbana, Ill., September 5, 2006—Imagine this scenario: a young Boxer puppy chews open a tube of polyurethane glue, accidentally left out by his owners who were using it to do repairs on their home, and swallows some of its contents.  The next morning to his owners’ surprise, the Boxer refuses his breakfast, and begins vomiting.  The puppy’s abdomen appears swollen and seems tender to the touch.  The bewildered owners take their pet to the local animal hospital, where they discover a large mass in the puppy’s stomach, and rush him into surgery to remove it.  After the successful procedure, the shocked owners are told the mass was a softball-sized lump of expanded and solidified polyurethane glue.
 
Unfortunately, this scenario has played out many times all across the country.  Since 2005, the ASPCA Animal Poison Control Center (APCC) has managed more than 135 cases involving exposures to expanding adhesives containing diphenylmethane diisocyanate.  More astounding is that this number represents an increase of more than 309% in expanding glue cases since 2002. 

“Any number of factors could be contributing to the increase, including the growing popularity of do-it-yourself projects or the increased use of this type of adhesive,” states Dr. Steven Hansen, Senior Vice-President and board-certified veterinary toxicologist for the ASPCA APCC.  “Whatever the reason, due to the rising number of cases, the importance of alerting companion animal owners to the dangers of expanding polyurethane glue products is clear.”

As diphenylmethane diisocyanate may not always be listed on the label, pet owners should consider any expanding adhesive product a potential hazard, and should be especially careful in keeping such products out of the reach of their pets. 

“A dog consuming even small amounts of adhesive containing diphenylmethane diisocyanate can experience serious problems as the product expands in the warm, moist environment of the stomach, forming a porous mass of glue,” says Dr. Hansen.  “This mass can block the gastrointestinal tract and cause a life-threatening surgical emergency.” 

And as with any potentially harmful substance, should an accidental exposure occur, it is important to contact a local veterinarian or the ASPCA Animal Poison Control Center for immediate assistance.

Note: Due to a statistical calculation error, the percent increase in cases from 2002 to 2005 was found to be incorrect. The actual increase in cases from 2002 to 2005 is 309%. We regret the error, and any unintentional misrepresentation of information it may have caused.
