Caring for a one-month-old German Shepherd puppy requires feeding them more than four times a day. It's crucial to control portion sizes to prevent overfeeding. Keep their living area clean, and let them enjoy sunshine regularly, as UV rays can help disinfect.

1. Due to their small stomachs, German Shepherd puppies should be fed small meals frequently. In the initial period after weaning, they should be fed more than four times daily. Around six months old, they should be fed three times a day. As they grow older, reduce the feeding to twice daily.
2. It's essential to control portion sizes and avoid overfeeding. Refrain from feeding them human food. Puppies have simple dietary needs and tend to eat anything offered. If they get used to human food, they may develop a dependence on it.
Human food has a different nutritional composition than what puppies require, leading to an unbalanced nutrient intake and impacting their development.
3. In addition to diet, you should also pay attention to the puppy's environment. When the weather is nice, let the puppy play in the yard, but avoid taking them out before they have received all their vaccinations.
When is a German Shepherd Considered an Adult?
Typically, a German Shepherd is considered a fully grown adult at 12 months old. At this stage, they will start to go into heat and seek mates, and their appetite will increase. Additionally, adult male German Shepherds typically have a shoulder height of about 60-65cm, and females around 55-60cm. Only a few German Shepherds may fall outside of this range.
