What breeds of dogs are born without tails? - briefly
Certainly! Breeds such as the Australian Shepherd and the Braque du Bourbonnais are often born without tails, a characteristic known as anury or brachyury. Additionally, some individuals of the English Bulldog and Boston Terrier breeds may also be born tailless, although this is less common.
What breeds of dogs are born without tails? - in detail
Several dog breeds are naturally born without tails, or with extremely short ones that may appear absent at first glance. This trait is often due to specific genetic mutations that have been selectively bred over generations. Here are some of the most notable breeds:
-
Australian Shepherd: While not all Australian Shepherds are born without tails, many are naturally bobtailed or have very short tails due to a genetic mutation. This trait is often associated with working ability and agility in the breed.
-
Boston Terrier: Boston Terriers are typically born with short tails that may appear non-existent. The natural bobtail is a defining characteristic of the breed, contributing to their distinctive appearance.
-
Brittany Spaniel: Brittanys often have naturally short tails or are sometimes born without tails at all. This trait is genetically inherited and does not affect the breed's overall health or performance as a hunting dog.
-
Pembroke Welsh Corgi: Unlike their cousin, the Cardigan Welsh Corgi, Pembrokes are usually born without tails due to a genetic mutation that has been selectively bred into the line. This natural bobtail is a distinctive feature of the breed.
-
Pharaoh Hound: This ancient breed from Malta is often born with very short tails or no tail at all. The Pharaoh Hound's natural bobtail is another example of genetic selection over centuries.
-
Old English Sheepdog: While not all Old English Sheepdogs are born without tails, many do exhibit this trait due to a recessive gene. This natural bobtail does not impact the breed's working abilities or overall health.
It is important to note that some dog owners may choose to have their dogs' tails docked for various reasons, such as preventing injuries during work or conforming to breed standards. However, this practice is increasingly regulated and often discouraged due to ethical concerns and potential health risks associated with the procedure. Natural bobtails in these breeds are a result of selective breeding over generations, leading to genetic traits that do not require surgical intervention.
