LONDON, Ontario (AP) - A dog trapped with other pets in a truck for several days alerted police in Canada by honking the horn.
Police said Friday that the muzzled dog _ along with two other dogs and two cats _ had been left in deplorable conditions without proper care in the parked truck.
Police say the discovery came a week after someone complained to the London Humane Society in Ontario about three dogs exposed to unsanitary conditions in a home.
The police statement says the residents left with the dogs, likely to avoid Humane Society officers.
Donna Hebert and Allan Folkins-Wyre were charged Thursday with several counts of cruelty to animals.
The animals have been taken in by the Humane Society.
