My dog's back legs are weak, swaying, and in a frog pose. Why?

Hi there and thank you for using Pet Coach to address your concerns. This could very well be related to arthritis of the back legs. The more arthritis develops, the more painful it becomes for dogs to walk. If there is hip dysplasia and this worsens over time, some dogs can appear to walk as if they are drunk with wobbly legs. I would recommend having Athena looked at by a veterinarian so that the appropriate treatment can be recommended. I typically recommend a multi-modal approach and use anti-inflammatory drugs such as Carprofen, pain medications such as Tramadol, Methadone or Gabapentin. Supplements that I would recommend would include Dasuquin with MSM, Adequan injections and Welactin omega 3 fish oil. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns.

It sounds like what you are describing is weakness. Did your pup have a neurologic exam? What we look for is evidence of pain (although this can sometimes be inconsistent in pets), loss of sensation to the feet (does he fail to flip his foot back over when the top of his foot is placed down?), and presence or absence of reflexes. The results of these tests can help to determine if it's neurologic in origin and what portion of the spinal cord may be affected. Although, it can sometimes be hard to differentiate orthopedic from neurologic disease. Plain xrays of the spine are helpful to rule out any bony abnormalities, and sometimes we can see evidence of narrow disc spaces, but ultimately we cannot see the spinal cord, nerves leaving the spinal cord, or the soft tissues. If a neurologic problem is suspected an MRI is often needed. But, there are also some other conditions that can cause weakness that are metabolic in origin (has your guy had any senior lab work recently?) or related to loss of signaling to the muscles (for example a disease called myasthenia gravis) or related to a degenerative process such as degenerative myelopathy. If there is a component of pain detected on exam then anti-inflammatory pain medication may help. If you feel like things are getting worse it would be a good time to have a re-evaluation with your family vet. Another option as well, if a neurologic process is suspected, would be to have a consult with a veterinary neurologist.

Thanks for using Petco Pet Education Center, formerly Petcoach! This may be due to a neurologic condition such as a herniated disc. I recommend that you have him evaluated by a veterinarian for further assessment and treatment. They would be able to check for this and treat him accordingly. Best of luck!

Pozzy may be having trouble with his back. Intervertebral disc disease may look like this. I would advise to get some radiographs done to see how the vertebra looks. If there is no obvious cause, a consult with a neurologist may be indicated. There may also be physical therapy exercises that may help as well. He would be young but degenerative myelopathy could also be a factor. The doctor should be able to get a better idea based on a physical exam.

Have Hopper examined by your veterinarian. Spinal x-rays may reveal arthritic changes that could cause low back pain and home end weakness. Pain management, physical therapy, swim therapy and/or cold laser therapy may all be options depending on the diagnosis.

Your dog could have arthritis which makes him unstable. He could also suffer from hip dysplasia (which can lead to arthritis) or have some compression of the spinal cord which can affect the hind leg movement. A vet exam is recommended to check for these issues. Some may improve with anti-inflammatory medication available from your vet. In the meantime, using small throw rugs on the floor (that have grip on the back so they don't move) may help your pup get around on the floor.

Thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry to hear Mitch is having hindlimb weakness. Weakness in the hindlegs in older dogs can be due to a variety of reasons, including arthritis, back discomfort, or an underlying neurologic issue, among others. Anti-inflammatories, pain medications, and supportive care (such as hydrotherapy and acupuncture) may all be beneficial options. I would recommend discussing what the best overall treatment plan for Mitch would be with your regular veterinarian, or seek a second opinion if you want further advice. Good luck!
