4 Injuries That Can Take the Wag Out of Your Canberra Pet's Tail

How the Tail Works
The tail is an extension of the spine, but it’s more mobile and flexible. A wedgelike bone at the base of the spine known as the sacrum anchors the tail. The subsequent tailbones (coccygeal, or caudal, vertebrae) get smaller and smaller along the length of the tail. Cushioning each tailbone are tiny joints and disc pads. Muscles put the wag in the tail and play a role in faecal control. Blood vessels and nerves are also part of the tail’s anatomy.
When the tail is injured, the damage can be as simple as the “Ouch!” from getting the tip caught in a doorway or as serious as heavy bleeding or severe nerve damage. The tail is prone to injury because it’s unprotected and frequently in motion.
Here are four ways that things can go wrong at the tail end of your pet.
Common Tail Traumas
Abrasions: Sometimes an accident causes scrapes, hair loss and bleeding. This can happen with cats, for instance, whose tails get caught in a car engine. Not a winter goes by that most vets in places where it gets cold don't have a cat come in with a fractured or injured tail from getting it caught in the fan belt of a car.
Clean minor scrapes, but take your pet to the veterinarian right away if the tail is bleeding or has serious skin or hair loss. A tail wrap can protect the skin while it heals. When skin damage is severe or extensive, healing can take a long time, and it can be painful. Sometimes shortening the tail is a better way to resolve the problem. The good news is that your pet won’t miss the piece that’s gone.
Happy tail: This type of injury occurs when a dog with an outgoing personality and a long tail repeatedly thwacks the tail against a hard surface such as a crate or wall. Really happy dogs — think Golden Retrievers or Cavaliers — or dogs with thin, delicate skin, such as Greyhounds, wag so hard and fast that a bleeding ulcer can develop on the tip of the tail. In chronic cases, the only solution is to amputate the end of the tail. Despite the name, there's nothing happy about this injury.
Fractures: Most commonly, tail traumas occur when a dog or cat is hit by a car, but the tail can also break when it gets on the wrong side of a closing door, is stepped on or hits the floor wrong when the pet falls off the lounge or bed. A simple fracture that occurs toward the end of the tail usually heals just fine on its own. Your pet won’t have to wear a cast or have surgery. The only clue that there was ever a problem might be a kink or bump in the tail, which develops because there’s no way to hold the tail still while it heals.
Nerve damage: There’s a good reason we teach kids not to pull a dog or cat’s tail. Damage caused by pulling — known as an avulsion injury — can affect the nerves and muscles that move the tail as well as the nerves that control urination and defecation. Avulsion injuries usually occur when the pet is hit by a car or the tail is yanked hard some other way. The nerves that serve the tail can be disrupted or badly stretched. Depending on the extent of the damage, the injury can cause the tail to hang limply, unable to move, or even affect the animal’s ability to urinate or defecate on his own. Nerve function may return in time, sometimes a month or more.
Which pets are most prone to tail injuries? Outdoor cats or dogs allowed to roam are at high risk, but any pet can suffer a tail slammed in a door or land wrong if they fall off the sofa or bed.
Take your dog or cat to the veterinarian if he’s unable to move the tail, has severe skin damage or hair loss, or is unable to urinate or defecate.
