Which Dog Breeds Have Curly Tails?
Some dogs have long straight tails, some have very short tails, and some have curly tails. Each breed is unique in shape and size, and some have curlier tails than others.
Curly tails can be just barely curved, c shaped, or corkscrew shaped. Curly tails in dogs are caused by genetics, for the most part. Specific breeds inherit the gene for a curly tail from both parents. In this case, it would be almost impossible for a dog of that breed to be born with a straight tail.
Other dogs have developed the gene for a curly tail over time, due to environment, climate, or purpose of the tail. Siberian Huskies, for example, have a long tail that is not naturally curly. However, as a result of needing to curl the tail around the body in order to keep the face and nose warm, husky tails developed a curve. Now, most Siberian Huskies will have a sickle shaped tail that hangs in warm weather but curls when they are sleeping or in cold weather.
Some dogs, like pugs, have very curly tails. This is a result of selective mating by breeders to produce puppies with double curl or spiral tails. This tightly wound tail has become the breed standard, and pugs with looser curls in their tails are considered substandard.
What Causes Curly Tails?
The tail of your canine pal is an extension of his spinal column, an additional series of vertebrae that extend past the hip ones. Normal spinal vertebrae are somewhat rounded and thick, like biscuits. In curly tail dogs, these spinal vertebrae are misshapen. They are flatter on one side than the other, making them fit together like slices of a cake. As these wedge shaped vertebrae stack on top of one another, a curl is produced.
In some breeds, there is just a slight irregularity in the shape of the lumbar vertebrae, giving the dog a slightly curved tail. In other breeds, the vertebrae are distinctly v shaped and cause a much more curved tail section.
Is a Curly Tail Harmful to a Dog?
If the dog has inherited the tail curl genetically, meaning one or both parents have a curly tail, then it is standard for that breed. In this case, the absence of a curly tail would be cause for concern. For example, a Pomeranian born with a straight, downward hanging tail would likely be suffering from some type of spinal trauma.
Likewise, in normally straight tailed dogs, like labs, a truly curled tail would be a birth defect and could signal spine or hip problems in that dog. If your normally straight tailed dog suddenly wakes up with a curled tail that won’t relax, consult your vet.
Other Causes for Tail Curling
In some cases, a curl in the tail can occur because the dog is trying to tell you something. In border collies, the tail normally hangs behind the dog in a slight arc. If the dog suddenly begins barking and curls the tail up over his back, he is sensing danger.
In small breeds like spitz or chihuahua, a curly tail can be used to help provide balance or stability when moving through tricky places or along the back of furniture or on window ledges.
Another common reason a dog might curl his tail is overstimulation or excitement. This can happen during a playdate at the dog park, or when a female in heat meets an unneutered male.
