IVDD Stages in Dogs

A plain-English overview

Veterinarians may describe IVDD severity in stages or grades. The exact system and treatment recommendation can vary, so use this page only as owner education and confirm your dog's status with a veterinarian.

• Milder cases may involve back or neck pain without obvious walking problems.
• Moderate cases may involve wobbliness, weakness, crossing legs, dragging toes, or trouble standing.
• Severe cases may involve inability to walk, paralysis, or changes in deep pain sensation.
• Loss of bladder or bowel control, sudden paralysis, severe pain, or rapid worsening should be treated as urgent.

Why stage tracking should be cautious

Owner observations are useful, but they are not the same as a neurologic exam. A dog that looks better or worse at home still needs the treating veterinarian's guidance for medication, crate rest duration, surgery decisions, and physical therapy.

IVDD Companion lets you record what you see without trying to replace the clinician's diagnosis.
