At a younger age, puppies will expend much more energy than their adult counterparts. This should translate and most likely will result in 3-4 meals per day up until 4-6 months. You should reduce their meals down to 2-3 around that time. Around 9-12 months, two meals separated in the morning and during evening is recommended.
Try giving your Boston Terrier 1-1.5 cups of top-rated dry kibble a day. To keep their compact body vibrant and healthy, you should feed them quality protein like Chicken or Lamb. Most quality manufacturers will top out at 20 to 27 percent proteins levels. Avoid corn and other grain food substances.
As always, you should have fresh and clean drinking water available to your Boston Terrier. Reward them with healthy treats like biscuits and bones to promote better teeth.
