4 Keys of the Long Hair Gene of the French Bulldog

Can you imagine a french bulldog with long hair? They are not frequently seen but really exist even though they are not easy to see on the street, but in social media we have found more than one and they have left us speechless. They are like our frenchies but with very long hair for the breed. It is about a genetic problem due to the combination of the hair genes of the parents.

Dougie and Ohhiburney are two beautiful frenchies which we follow on Instagram that do not leave us indifferent to their originality, so we decided to investigate a little more and I share it with you because it’s adorable.

The Long Hair Gene in the French Bulldog

#1 What is the long hair gene in dogs

The long hair gene is a gene that produces a layer with higher capillary length in numerous breeds. It poses no threat to health, however in some races it is considered absent or genetic alteration of the breed and many criticize them but the dogs are healthy and they do not have to have any problems.

The long hair gene is an autosomal recessive disease, meaning, no genetic dominance phenomenon but for this heritable trait to be transmitted it is necessary that the offspring receives the gene from both parents.

#3 Why does this “anomaly” occur

The dog, in this case the french bulldog has long hair because the breeder probably crossed a female and a male with the gene although they have short hair being carriers thereof and therefore their puppies are born with long hair like some frenchies and other races. A dog with two copies of the recessive gene variant are affected, will express the phenotype and pass a copy of the variant gene to their offspring 100% of the time. A dog with a copy of the variant gene is a recessive carrier, that do not express the phenotype themselves, however, They are for the variant gene to their offspring 50% of the time. A dog that does not have any copies of the recessive gene variant is clear, and will never produce offspring affected.

#4 How to detect this gene

There are DNA tests that allow to detect the gene, if they both carry it probably the puppies will be born with long hair, and if only one of them carries it probabilities are halved. It is important that breeders of race do this type of testing to avoid unwanted litters being born that in some cases will not easily find a home since who is looking for a french bulldog of race does that under the standard.

Is Important to Understand the Genes of your French Bulldog
