How Big Is A Fully Grown Bichon Frise?

Bichon Frise puppies are like tiny fluff balls when they are born. As they grow, they become bigger and start to look like adult Bichons. Usually, Bichon Frise stop growing in height when they are around 8 to 12 months old. That means they reach their full size and don’t get taller after that. Imagine them as little adults! However, even though they stop growing in height, they continue to fill out and develop more muscles until they are about 18 months old.

So, it’s like they’re finishing their growing journey. You might notice that when your Bichon is a puppy, they have lots of energy and play a lot. As they grow up, they may become a bit calmer. It’s part of becoming a mature dog. Also, their coat, that beautiful fluffy fur, continues to grow and might change a bit in color or texture as they get older. It’s important to take good care of your Bichon during this growing time.
