In this game, animals will play a crucial role. Without them, your farm may not experience much in the ways of success. Back to Nature makes sure to provide you with a variety of animals, and so you can acquire on your farm a dog, a horse, sheep, cows, and chickens.
The first day you get your farm, you shall receive the dog. Before you begin your work on the farm you are given the option of naming him. The dog starts out as a puppy, and takes about three months to grow up.
The dog requires a certain amount of care in order to be of use to you. Pick him up every day (stand next to him an press the X button), and his affection for you will increase. After you buy the ball from Won, you can also play fetch with him–The more you play with the dog, the better he'll do in the Dog Race. Fortunately, your furry companion does not require feeding.
If you take good care of him, he can also help in chasing away stray dogs that might come to terrorize your animals.
Sometime in Spring of the first year, you can visit the Yodel Farm and they will give you a horse.
The horse is useful, convenient, and easy to take care of. He has his own stable, which is separate from the barn. The horse, when first received, is still but a pony, and so cannot be used to ride anywhere. You will have to brush him (buy the brush from Saibara, the blacksmith) and talk to him every day in order to increase his affection towards you. A year later, when he's grown, you will be able to ride him, though you will not be able to talk to him anymore. Like the dog, you don't need to feed your horse. Taking good care of him has its own rewards, as with proper handling your horse shall compete well in the Horse Races.
The horse's saddle also has two pouches in it, which can be used as mobile shipping bins. Simply put any type of crop into the pouches and they'll automatically be sold, which is identical to the shipping bin's function.
Chickens are easy to take care of, and they'll probably be the first animals purchased on your farm. The chickens can be bought at the Poultry Farm, and they are convenient in that you only ever need to buy one: your chicken shall lay an egg a day, and this egg can be hatched to produce yet another chicken. When the chicken is first bought, it will have to be fed for three days before it will start laying eggs
You buy chicken feed from the Poultry Farm, or you can take corn and throw it into your windmill and produce your own feed (one piece of corn makes 10 units of feed). However, you can also put your chickens outside and plant some seeds to make them a pasture. They will automatically eat from this, and it will save you from feeding them yourself. Remember to use lumber to make a fence around the area in which you would like your chickens to remain; otherwise, they will get lost,–or even worse, they will be terrorized by stray dogs. The chickens should also be brought inside whenever it rains. If you neglect to feed your chicken for one day, it will not produce eggs for three
Cows are probably the most profitable animal you can buy. When you purchase your first cow, it will take approximately 15 days until it starts to make milk, after which time it will produce milk every day (so long as you continue taking care of it). Given that they are the most profitable animals, cows are also the most expensive to buy; you can find them on sale at the Yodel Farm.
Make sure to brush and talk to your cows every day. Like the chickens, you can also put your cows outside. Make a fence with lumber, plant grass, wait until it grows, and the cows will eat that instead of fodder. You can also chop the grass with your sickle to convert it to fodder, and it will automatically be put into your silo. When it rains, you should bring your cows inside, or they will get sick. The bell, bought from Barley for 500G, can be used for this. The bell makes all of the cows and sheep gather around you, which makes the task of pushing them into the barn by hand much easier.
Sheep are very profitable animals, bested only by the cows, with whom they share the barn.
Sheep are cared for in a way that is identical to the handling of the cows: brush and talk to them once a day, and the more they love you, the more wool they will produce. Each sheep costs 4000G. As soon as you buy a sheep, you can shear it right away, although the wool will not be worth much, since it doesn't have a lot of affection for you yet. Once shorn, wool takes seven days to grow back.
Again, like cows, you can put the sheep outside. Build a fence with lumber, plant grass, and they will eat it once it grows. You can also use the bell to herd sheep back into the barn when it rains; it will draw them close to you, and you need only push them into the barn.
