Behavioral changes are often medically related. Important information here.
Tethered cord syndrome is a neurological condition where the spinal cord is abnormally attached to surrounding tissues inside the spinal column. Instead of moving freely as the dog bends and stretches, the spinal cord is pulled tight. This can cause nerve pain, mobility issues, and bladder or bowel problems. Be aware that a normal MRI does not always rule out the condition. Occult Tethered Cord may only be confirmed at surgery.
Dogs with tethered or occult tethered cord may show:
- Unusual tail base or sacrum appearance: sacral dimples, indentations, or hair pattern changes (raised, wavy, or flicked coat over the spine).
- Lameness or hind limb issues: intermittent limping, skipping steps, or kicking out with the hind legs as if reacting to nerve pain.
- Weakness or imbalance: swaying hips, reluctance to jump or climb, difficulty lying down or getting comfortable.
- Bladder problems: urinary incontinence (especially after exertion or travel), frequent urinary tract infections, or straining to urinate.
- Bowel issues: constipation, incomplete emptying, or general digestive sensitivity.
- Changes postures: reluctance to sit or lie in flexion, preferring to stand or stay extended.
Behavioural Symptoms
Because chronic pain and neurological discomfort affect how dogs feel and respond, behavioural changes are often one of the first signs:
Inability to settle
Touch sensitivity
Aggression or reactivity
Noise or movement sensitivity
Extreme behaviours: compulsive chasing (tail, shadows, or movement), excessive barking, or destructive chewing.
Over arousal
Without intervention, nerve damage may become permanent. Dogs living with undiagnosed tethered cord are often labelled “difficult” when in fact they are in chronic pain.
Keep a diary of symptoms (physical and behavioural).
Note any changes in toileting, gait, or reactions to handling.
Take photos or videos of unusual movements, postures, or behaviours.
Discuss your observations with your vet.
