One of the most important stages in developing a dog's personality, according to Diers, is the socialization stage, which lasts between 3-12 weeks of age.
Puppies should be taken out every hour, as well as shortly after meals, play and naps. All puppies should go out first thing in the morning, last thing at night.
Most puppies do well eating 4 meals of puppy food a day (maybe 5 for the tiniest of pups). By 12 to 16 weeks of age, puppies can usually eat three times a day.
Once your puppy is 6 - 8 weeks old, they can have their first vaccinations – usually called the primary course. This consists of two or three injections, given.
