Hello,
This is a hard question to answer for a few reasons. One we hardly ever get a confirmatory diagnosis on this disease. To do that you would need an mri or ct and an csf tap. Without them we guess that it is IVDD which is the most common cause of acute paralysis or weakness. So trying to understand what is or isn’t normal when we aren’t sure of the diagnosis is difficult.
If it is IVDD then yes it is not uncommon for them to get worse as we try to get them better. The worsening can occur because more of the disc is slipping into the spinal cord area or because another disc is also slipping. Or because the damage to the spinal cord is progressing. Please call your vet with any questions or concerns or changes to your pet. They can help. Best of luck.

I haven’t used it, nor had clients who have. But I’ve seen them at the trade shows. I don’t think there is any hard evidence or studies to support their use. But I also don’t think they do any harm. If you use it and like it will you let me know.?

Hello,
I suppose I would ask why do you think he is walking? I’d be bored? Felling better? Stressed? What do you think? In my experience they start walking when the pain dissipates so I am all for walking and maintaining muscle mass. But, it doesn’t displace the need for physical therapy to regain lost nerve function and muscle mass. Ie you still want to encourage them to use the weak legs and not just the sting and functional legs. As long as it is safe (no stairs or access to danger) and they are not causing abrasions on the feet they can’t use normally, AND you can keep doing your pt then I am ok with it.
