Smaller dogs obviously have a different timeline for adulthood since they usually have less growing to do and therefore require less time to do it.

However, you will find that your Miniature Bull Terrier will take a bit longer than other small breeds to reach their full size. This is usually achieved in 11 to 12 months of age, while other breeds only take 6-8 months.

Standard Bull Terriers are seen as full-sized adults when they have reached the period of 1 year to 14 months old. That said, you may find that they would continue to add muscle until they are 2 years of age.
