hmmm, a poodle doesn't sound like an outside dog, do you mean outside all the time, day and night? I hope they realize that all dogs will require time and attention, especially at first.

When I think of a farm dog I think of a border collie - the herding dogs. They are extremely smart but have a lot of energy - which is why a farm would be good for them if the dog was allowed to run.

However it sounds more like they want a dog that just kind of hangs around the outside of the house to greet visitors - I would suggest they find an older dog at a shelter that fits the personality and size they want. From the conditions you have stated it sounds like a puppy would be a bad idea.
