A miniature dachshund feeding chart by age, amount is determined by age, weight, and activity level. Generally, a miniature dachshund puppy (below 12 months) needs around ½ to 1 cup of good-quality puppy food per day, divided into 3–4 meals, while the grown-up miniature dachshunds, aged between 1–7 years, need ¾ to 1 cup per day, divided into two meals; se-niors, 7 years and above, need ½ to ¾ cup every day because of slow metabolism.
