In Canada you can find dogs, cats, horses etc, in almost every family. These are their pets. People love these pets and pets are their good friends. Before they keep them at their houses, they take them to animal hospitals to give them needles(针) so that they won't carry disease(疾病). They have special animal food shops, though they can get animal food in almost every shop. Some people spend about two hundred Canadian dollars a month on animal food.
