     The mothers met while walking their beloved dogs in the local park, the Donald Mcdonald Reserve,

several years ago and developed a friendship that began with small talk about their pets. This quickly turned

to afternoon get-together, where kids, dogs and grown-ups formed firm friendships.

     Now the pair and their pets meet several times a week on the grass near Sandringham College, a place

for a huge network of dog owners who have formed all kinds of friendships and a good old-fashioned sense

of community. Dogs, it seem, are good for social life.

     The combination (结合) of excited kids and dogs could be a recipe (处方) for disaster and Miller says it

is surprisingly harmonious (和谐的). "There are some other people who don't have kids but have started to

meet us quite regularly," she says. "the other day, there were seven dogs, five adults and six children all

walking around the park together."

     Friendships formed through pets seem to cross cultural and age barriers (阻碍) and often include helping

when someone is sick or needs help to care for a bet. A woman says she's answered several SOS calls from

elderly people who have become ill suddenly and need a help. "The friendships are such that you see these

people every day and you get to know them and they trust you with their pets and know they can call you at

the last minute," she says.

     One dog owner says that, even as a child, she noticed how dogs could act as conversational ice-breakers

for adults. Like people, dogs are also social creatures. "Dogs need to meet others," she says, "they are pack

animals."
