When a French Bulldog is bred with another, smaller breed dog, to achieve the smaller size Frenchie.

The appearance of a mixed French Bulldog will depend on the dog breed they were mated with.

The crossbred Frenchie can take on the appearance of both breeds, look more like the second breed or look like a scale down version of the standard size French Bulldog.


Another way of breeding for a small size Frenchie is when a breeder purposely introduces the dwarfism gene found in a purebred dog. The result of this type of dwarfism is called Chondrodysplasia.

The bones in dogs with Chondrodysplasia don’t reach their full-size potential resulting in dwarfism.

It’s important to understand that Chondrodysplasia may cause various health issues including bowed limbs, distorted joints, lameness, and severe impairment in growth.

Shorter legs are a characteristic of Chondrodysplasia.


The breeding of runts of a litter to other runts from another litter will increase the likelihood of producing a runt, or smaller, size dog.
