Factors Affecting Growth and Development
Genetics
Parental size strongly influences a Boston Terrier's adult size. Puppies from larger parents typically grow into larger adults, while those from smaller parents tend to remain more compact.
Nutrition
Proper nutrition during growth phases is crucial. High-quality puppy food formulated for small breeds helps ensure healthy development and appropriate weight gain.
Exercise and Activity
Regular, moderate exercise supports proper muscle development and helps maintain a healthy weight. However, avoid excessive exercise during rapid growth phases to prevent joint stress.
