Natural bobtail
Encyclopedia
A natural bobtail is an animal's tail which due to a mutated gene
grows unusually short or is missing completely. The genes for the shortened tail may be dominant or recessive.
Due to legislation restricting or preventing docking, natural bobtails are growing in importance in the hobby of dog fancy
ing for some traditionally docked breeds. For example, one Boxer
breeder and geneticist in England has successfully petitioned the Kennel Club
for permission to cross Corgi
s into his lines and then backcross to Boxers, introducing the gene into his lines. This would have been unheard of in decades past. A number of these bobtail Boxers have been successfully exported to various countries around the world.
