40天德牧一般吃多少狗粮

A 40-day-old German Shepherd puppy will typically eat around 3-4 cups of puppy food per day, divided into 3-4 meals. This can vary depending on the puppy's size, activity level, and overall health. It's important to consult with a veterinarian to determine the specific needs of your puppy and to monitor their growth and development.
