My dog suddenly can't move his back legs and back end. What's wrong?

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.

Oh dear! This is a very serious problem - I'm afraid she really has to see a vet right away. She may have a herniated disc in her back causing the paralysis, or some other neurologic problem affecting her spinal cord. She may be in pain, or she may have no feeling at all in her rear legs - it's impossible to say without an exam. She needs immediate treatment to have a reasonable chance of regaining function in her rear legs, I'm afraid there's nothing you can do at home that will help her. If costs are a concern, you can see if there is a low-cost SPCA clinic in your area that could help. You could also apply online for Care Credit, which is a payment plan accepted by most vet clinics: www.carecredit.com

It sounds like Jack has severe diarrhea, and he's likely dehydrated from it, causing him to be weak. This is a medical emergency, and he has to see a vet now. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

Poor Turbena! I'm afraid this is very concerning. Loss of function in the rear legs is most often due to a "slipped" or herniated disc in the spine, but could also be due to some other neurologic problem or illness. This problem needs immediate treatment for the best chance of recovery, so I would recommend taking Turbena to the vet now. He/she can do a complete neurologic exam as well as x-rays or other testing if needed to help diagnose the problem and get her started on appropriate treatment right away.

Poor pup! This sounds like a potentially serious problem, so I would recommend taking him to an emergency clinic today to be seen. He may have a neurologic problem of some kind, may have injured himself somehow, or may have ingested something toxic. The ER veterinarian can do a completely neurologic exam and may recommend blood work, x-rays, or other testing if needed to help figure out what's wrong. If you're not sure where to go, try calling your regular vet's office - their voicemail message should have contact information for your nearest ER or an on-call doctor for emergencies.

Charlie needs to see the veterinarian today. Losing the usage of the hind legs is serious and can indicate many conditions like compression of the spinal cord, cancer or a blood clot. This can effect the ability to voluntarily urinate long term and needs to be addressed asap otherwise there can be permenant damage. The damage can occur in as little as 24 hours. Best of luck and please feel free to post any additional questions.
