My dog suddenly can't walk, no wounds or swelling. What's wrong?

Difficulty walking is a situation that always warrants a visit to your veterinarian. We could have a musculoskeletal injury or a neurological issue, such as a herniated/slipped disk in the spine compressing the spinal cord. Your vet can do an examination to see if there are neurological deficits and may also recommend an x-ray to help determine the cause of the trouble walking, and if it is related to the swelling of the tail. Limber tail doesn't normally cause a swelling of the tail, but can cause the tail to be carried strangles, where it will stick out for an inch or two and then hang down limply. If the tail is truly swollen I would be more worried about an injury and x-ray may be needed.

Not being able to walk all of a sudden is an emergency and you need to take Paris to your vet now. If this is caused by a prolapsed disc, then time is of the essence, ie treatment with NSAIDs, pain medication and strict cage rest as early as possible increases the chance of recuperation. There can be other reasons for not being able to walk, and only a hands-on exam will facilitate a diagnosis. Your vet will want to do radiographs, possibly blood tests and do a thorough orthopedic and neurological exam.

I would be worried about Spike. Things that come to mind are a disc that has ruptured into the spinal canal, a fibers clot, a blood clot, a tumor or somehow acquiring an injury. I would recommend to take him into the veterinarian's asap to get him checked out. The doctor may want to do an x-ray or may recommend referral to a neurologist based on what they find. Best of luck with Spike!

Given your description, I would suspect intervertebral disc disease. It is similar to a slipped disc in humans, and can cause extreme pain and paralysis. These types of injuries are time sensitive, and prognosis goes down substantially after 48 hours. I am not trying to scare you, but you should bring him in right away to have him evaluated. Other possibilities include a torn ligament in his knee although the "dragging" does not fit. If he does have disc disease, paralysis and severe pain are good indications for surgery. If he has some function, and pain can be managed, then medical management with anti-inflammatories and pain medications is possible.

At his age I would worry there is a injury affected his back or hips that is causing him to be weak and unsteady. If he is overactive and jumps frequently, he may have damaged part of his spine to cause swelling and compression on the nerves. The best thing to do in confine him so he does not continue to injury himself until you can get him to the vet for an evaluation and radiographs

Oh no, that's not good! Jessie could have suffered an injury to his spine or hips causing him to suddenly be unable to use his back legs. It's quite serious that he can't use them, and I would have him seen by a vet tonight for a physical exam and x-rays to diagnose what is causing his symptoms. Once a cause is found, the vet can treat him. Please bring Jessie into an ER vet or find a vet on call to see him now.

It sounds like your dog is uncomfortable or painful from some reason. He may have a back injury, a disc problem, or hip problem, or even abdominal pain. Your pet needs to be seen by your vet for an exam, bloodwork, and possibly x-rays to determine the cause for your pet's symptoms and get him stated on treatment.
