Why did my old dog suddenly cross hind legs and struggle to jump?

I'm sorry to hear that Angel has been having so many problems with her hind legs. Arthritis alone does not typically cause the hind legs to cross over. Instead, this type of issue typically occurs more from neurologic disorders or severe cases of hip dysplasia. Consider giving good quality fish oil supplements ( http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=19121 ) and glucosamine and chondroitin supplements ( http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=34368 ) to help with inflammation and cartilage protection. I also recommend taking Angel to her vet to have her gait and hind legs assessed to try to get to the bottom of this situation. I hope that all goes well!

This indicates that she has some degree of damage to the spinal nerves or peripheral nerves that control that leg. This can happen when they are hit hard by something, or (more likely) when they have a lower-spine disease. Old dogs tend to be more susceptible to various spinal cord problems that develop with age. These can be treatable though, so it's best to take Trixie for a vet evaluation sometime soon. The vet will be able to narrow-down the cause of this problem and provide pain relief (these conditions are usually very painful). For now, it's best to restrict her activity, as this can worsen her condition. Do not allow her to run, jump, or go on long walks until advised otherwise by your veterinarian. I hope that helps and Trixie gets better soon.

Thank you for submitting your question regarding Ben. He sounds painful with his struggling to move and crying. He could have arthritis, back pain or a muscle strain. If he was particularly playful yesterday or this morning, he may have over done it and be sore now. Back pain is more common in small breed dogs. It is demonstrated by a reluctance to do stairs, jump on furniture or even the inability to properly use a limb. Arthritis tends to be more common in larger dogs. It is usually a gradual slowing down or stiffness, but can be exeracerbated by hard play. Ben will need to see his veterinarian to determine the source of his pain. In the meantime, keep him quiet and do not give any over-the-counter pain medications. I hope this information helps!

It sounds like Bonbon may have hurt himself, and yes I would be worried since this is not normal behavior. It could also be that he is suffering from arthritis, which can be common in senior dogs. I'd give his vet a call in the morning to have him examined. If he is suffering from arthritis, the vet can prescribe pain medications for him. Please do not give him any human pain medications, as many are toxic to dogs and can be fatal if given. Best of luck, I hope this helps!

Lucas's back legs may not be working properly due to age related changes such as arthritis, or due to reduce nerve sensation to his hind legs, which can be caused by problems with his spine or brain. I would have Lucas seen by a vet for this. The vet can diagnose what is causing the problems with his hind limbs, and can discuss treatment options with you.

He likely already had arthritis in his hips and back and getting trapped in a bag caused him to panic. He most likely kicked and panicked and hurt his back and legs This can cause weakness and swelling around the spinal cord and back muscles which make to worse. He should see a vet as there is medication to help with pain for him to regain his strength

Your dog may just be feeling worse after having to get out and about at the vet. Trips like these can be very stressful and hard on older dogs. Your vet probably also did an orthopedic exam, flexing and extending his joints, which could make him more sore. It is possible, although less likely, that your dog is dragging his legs because of spinal damage. If you pinch his toes and he can feel it then this is probably not the issue. Let you dog rest comfortably for now and continue giving the medication as prescribed. If he is not improving within about 24 hours you may want to consider going in for a recheck or asking your vet for additional pain medication. Best of luck.
