Akitas generally take a bit longer to develop into their full adult size. This is typical for large breed dogs that need more time to grow than smaller-sized dogs do.

Most Akitas will reach close to their full size by the time they are approximately 10 months old. However, until they reach the age of two, they will continually gain weight. 

The size of your Akita really depends on their age and their lifestyle. The foods they eat and level of physical activity, play a major role in their weight and health at any given time.

Another way to check your Akita’s development is to look at their paws. If their paws still look too big next to the legs and body, then they most likely have a lot more growing to do as this is a characteristic of a puppy. Looking at an Akita growth chart should give you a good idea about your dog’s expected weight.
