Dogue de Bordeaux Fully Grown

The answer to this question is not as easy as you may think because dogs have different growth rates which are determined by a myriad of factors.

Dogue de Bordeauxs are considered fully grown when they are approximately 19 months old. This age is the same for both males and females.

After they are fully grown, it does not mean that they will stop gaining weight.

You can expect your Dogue de Bordeaux to weigh about 120 to 140 lb when they are adults. Note that this is an average range since some dogs may weigh more or less than this depending on their lifestyle.

They usually attain a height of 23 to 27 inches. Even though males are slightly larger, there is little variation. 

Even though Dogue de Bordeauxs are sturdy, they don’t need an endless amount of space the way other dogs do. They are an easy-going breed so as long as they are comfortable and able to move around freely they will be happy.

They are not as energetic as other breeds so outdoor space is not that important to them, but they still require physical activity in the form of a walk or playtime.

Furthermore, they should not be kept inside an apartment room all day.

The food must be properly prepared to the right consistency so that it is palatable to your puppy.
