Dogs back legs have become weak in the last couple of days.

Dogs back legs have become weak in the last couple of days. He's a springer spaniel, 4.5 years old.

Aloha! You're speaking to Dr. Michael Salkin
Would you describe Tonto as ataxic - "drunken sailor" - on his hind legs? Are they crossing underneath him? Is he dragging his paws/nails? A simple soft tissue injury is always possible but when both hind legs are involved, a myelopathy (spinal cord disorder) is considered. The most common of the myelopathies is intervertebral disk disease - a "slipped disk" which can be quite painful and account inappetence.

Tonto's vet will want to carefully palpate (feel) Tonto's spine/back to see areas of hyperpathia (increased sensitivity) exist. Tonto's conscious proprioception (knowing where one's legs are in space) and nociception (deep pain perception) should be assessed as well as they give us a prognosis . In most cases, a simple disk will remiss within 3 weeks. An emergency situation exists if peracute (sudden) paresis (weakness) or, indeed, paralysis is noted.

Please respond with further questions or concerns if you wish.

No his legs are not crossing, he just has difficulty getting from a lying to a standing position, and can't jump onto the couch, he can only manage to get his front paws up on the couch. He also looks as if he has difficulty going into a sitting position.
Thank you. When those symptoms are seen, I also need to consider hip dysplasia - osteoarthritis of his hips - and the cauda equina syndrome - an osteoarthritis involving the very last few segments of his spinal column. These conditions are diagnosed with X-rays. A slipped disk may also show up in X-rays but if my physical exam of my patient is suspicious enough disk, I'll waive X-rays and proceed to prescribe a nonsteroidal antiiflammatory drug (NSAID), and perhaps a narcotic analgesic and skeletal muscle relaxer.
