6. Sleep Fragmentation & Frequent Pacing (Can’t Settle Down)
A comfortable dog curls up and enters deep REM sleep within minutes. A dog suffering from silent orthopaedic, spinal, or visceral pain experiences severe sleep fragmentation. They may stand up, circle five or six times, lie down for thirty seconds, and immediately get back up to pace across the room.
This inability to get comfortable happens because the physical pressure of their body weight against the floor exacerbates inflamed joints, tender internal organs, or compressed vertebrae. If your dog wanders aimlessly at night or continuously changes sleeping spots on hardwood floors, an orthopedic evaluation is essential.
7. Sudden Aggression or Snapping When Touched (Hyperesthesia)
Has your previously sweet, gentle dog suddenly growled, flinched, or snapped when you pet their lower back, touch their collar area, or brush their hips? Owners frequently misinterpret this as a behavioral defiance or “bad attitude.”
In veterinary medicine, this defensive reaction is known as hyperesthesia—an exaggerated pain response triggered by touching inflamed nerves or tender muscular trigger points. The dog is not being mean; they are acting purely in self-defense to prevent excruciating physical pain from being touched.
