Flea-control product glues dog to inside of crate

From Edie Lau and the VIN News Service, this odd report:


A veterinarian presented with a peculiar case of a poodle stuck in its crate last week traced the problem to the pet’s spot-on flea treatment.

Residue from the product Advantage, which was applied between the poodle’s shoulders, somehow came in contact with the plastic base of the animal’s crate, dissolving the plastic and causing it to adhere to the dog’s belly.

When the dog wouldn’t come out of its crate the next morning, its concerned owner brought the dog, crate and all, to Dr. Tej Dhaliwal of North Town Veterinary Hospital in Ontario, Canada. Following two hours of sleuthing, Dhaliwal concluded that benzyl alcohol, an inactive ingredient in Advantage, was to blame.

Bayer Animal Health, maker of Advantage, acknowledged that the flea treatment was the likely culprit and offered to pay the owner’s veterinary bill, compensate him for loss of salary and replace the crate, Dhaliwal said.

Bob Walker, a spokesman for Bayer in the United States, confirmed that Advantage contains benzyl alcohol, which reacts with certain plastics. He said he consulted with colleagues in veterinary services and was told, “We know it can happen, but we’ve never seen it.”

Walker said a lead veterinarian in the department thought that most of the veterinary community was aware of the potential for the product to react with plastic. Walker said that he personally had not heard of such a thing before. He added, “My counsel would be, if you’re not aware, you need to be aware.”
