About the sheep -- they also have the thickest wool at the end of the winter and in the spring.

To shear sheep in the spring is a good time because it allows them to be relieved of their winter wool before the summer season arrives. Sheep have thick woolly coats, and if not sheared, they can get overheated in the summer months. Shearing their wool in the spring ensures that they stay cool and comfortable during hotter weather.

A sheep dog is specifically trained to work with sheep and assist in herding them. When sheep need to be moved from one location to another, sheep dogs are used to gather and guide them. They instinctively understand how to control the sheep by using their body language and barks. Sheep dogs are invaluable in assisting farmers in managing large flocks, ensuring that the sheep move in the desired direction and stay together as a group. Additionally, sheep dogs can also help in separating sick or injured sheep from the rest of the flock.

Milk is heated before it is put into containers mainly to kill any harmful germs or bacteria present in the milk. This process is called pasteurization. By heating the milk to a specific temperature and holding it there for a certain period of time, it helps reduce the risk of illness caused by consuming contaminated milk. Pasteurization is an important step in ensuring the safety and quality of milk products before they are distributed to consumers.
