When Do French Bulldogs Heads Get Bigger?

French Bulldogs, also known as Frenchies, have become one of the most popular breeds of dogs in recent years.

With their adorable flat faces and bat-like ears, it’s no wonder why they are so beloved.

But when do French Bulldogs’ heads get bigger? In this article, we’ll explore the genetics, diet, and age at which French Bulldog heads reach their full size.

Physical Characteristics of French Bulldogs

French Bulldogs are small dogs that typically weigh between 16 and 28 pounds.

They have a short muzzle, a broad head, and large, round eyes.

Their ears stand erect, and their tails curl up over their backs.

They usually have a short coat that can be any color or pattern.

Genetics of Frenchie Head Size

The size of a Frenchie’s head is largely determined by genetics.

Breeders can select for larger heads when breeding dogs, but the size will still be limited by the genetics of both parents.

It is important to note that larger heads can lead to health problems such as difficulty breathing or birthing puppies, so breeders should be careful when selecting for this trait.

The Impact of Diet on Head Size

A Frenchie’s diet can also play an important role in its head size.

A balanced diet with all the necessary nutrients will ensure proper growth and development of the head and other body parts.

Overfeeding or underfeeding can lead to an abnormal growth rate, which could affect the size of the head at maturity.

Frenchies typically reach their full head size at around 12 months old.

However, depending on their genetics and diet, some people may take longer or shorter.

It is important to remember that even if two Frenchies are from the same litter, they may not reach their full head size at the same time due to differences in diet and genetics.

Health Implications of Head Size

As mentioned earlier, larger heads in French Bulldogs can lead to health problems such as difficulty breathing or birthing puppies due to overcrowding in smaller spaces such as birth canals or airways.

It is important to monitor your Frenchie’s growth rate closely and consult your veterinarian if you notice any issues related to its head size or development rate.
