If your dog has recently been involved in a traumatic event, such as being hit by a car, being unable to move may be explained by that trauma. However, there are many reasons why canine paralysis can occur that are not as easy to distinguish. A few of these causes are tick bites, intervertebral disk disease (IVDD), bacterial infections like rabies or tetanus, and tumors. Any of these underlying issues may cause your dog to become unable to walk, have trouble moving around normally, experience constipation, and more.
Tick Bites
These nasty little bugs can be found virtually everywhere, especially in heavily wooded areas, and have a rather unfortunate bite. If your dog is bitten by a tick that contains this toxin, the toxin can be passed into the bloodstream of the dog and may lead to paralysis. In most cases, the toxin causes symptoms such as vomiting and slow movement. But, in a rare event, immediate paralysis can occur. If you notice that your dog has been bitten by a tick and is showing signs of paralysis, get him to the vet immediately as this paralysis can be fatal.
Intervertebral Disk Disease (IVDD)
This disease is most commonly found in dogs with long bodies such as the Dachshund. In older dogs, or dogs that experience spinal trauma or some kind, IVDD can result in the paralysis of the hind legs. When the dog’s spine experiences ruptured cushioning disks (located between each of the vertebrae) the disks press against the spinal nerves, causing pain and possible paralysis. IVDD has the possibility of being treated with medications provided by your veterinarian that can help your dog to overcome the injury and continue living a comfortable life, but some situations require surgery.
Viral or bacterial infections
Infections such as tetanus or rabies can be a factor when it comes to a dog being unable to move. As these infections are often fatal, treatment by your veterinarian is recommended.
Tumors
If a tumor develops on your dog’s spine paralysis might occur. A tumor causing paralysis may occur slowly. It is of the utmost importance to get your dog medical help when a tumor is the issue.
All of these causes are extremely dangerous, and while some may cause paralysis slowly and can be reversed, each one can be deadly. See a vet immediately if you notice your dog showing any signs of loss of mobility.
