All grounds were inspected for safety. Cast and crew members were instructed on the animals’ proper handling before filming began. Whenever dogs were to be near each other or near actors, they were introduced to each other before filming began and given time to become comfortable and familiar with each other. Whenever a dog is seen performing such mild action as sitting, lying down, walking (on- or off-leash), or jumping a short distance, trainers placed the animal on its mark and stood off-camera, using hand signals and verbal commands to cue the actions, which the trained canines were accustomed to. When a dog runs by itself, the streets were closed to the public — only cars that were part of film were nearby and they moved slowly and at a safe distance from the animals. Trainers either doubled as actors whenever possible or stood just off-camera to direct the dog where to run or walk. They allowed the dogs to set their pace and stop along the way if they wanted. All food the dogs ate was deemed safe for consumption, and takes were limited to prevent overeating. All animal clothing was custom-made, and each animal was accustomed to wearing it. Anytime Georgia the dog is shown carrying things in her mouth, they were lightweight props that she was comfortable with and well-rehearsed to carry. Whenever the bulldog, Cooper, is seen chewing on something, the items were safe for chewing and this was the dog’s natural behavior. Whenever dogs are shown knocking items over, such as dinner plates, the items were plastic props that posed no harm to the animals. To get Romeo (a Chinese crested dog) and Juliet (a poodle) to kiss in two scenes, a thin piece of plastic smeared with baby food was held between the two dogs, who were cued to lick it, making it appear as if they are kissing. The rain that Friday runs through in the alley was created with a special effects machine, and it did not faze the dog. The scene in which Bernie (Don Cheadle) calls roll for the dogs in the hotel was filmed in several separate shots using about six dogs at a time and then edited together to make it appear as if all the dogs were there at the same time. The dogs seen on treadmills were placed on real treadmills, which were turned to a slow setting depending on the size and speed of each dog, while trainers stood nearby. All barking and howling was a cued behavior.
