It is tempting to attribute slowing down or unusual behavior in a senior dog to age. But a new head tilt, repeated falls, seizures or one-sided weakness should not be written off as normal aging. Pain, orthopedic problems, inner-ear disease, brain conditions and metabolic illness may overlap in appearance.
Useful observations
Note whether weakness is sudden or gradual, whether your dog can stand and walk, whether awareness has changed, and whether eating, drinking and bathroom habits remain normal. Record the time of episodes and changes in current medications. Videos can be helpful if they can be captured safely.
Tests depend on the pattern
A veterinarian may examine gait, reflexes, balance, ears and eyes and recommend blood work to evaluate systemic causes. Imaging or a veterinary neurology referral is sometimes appropriate. Hearing loss or cognitive changes can contribute to behavior differences, but they do not explain every fall or collapse.
Make the home environment safer
Until an assessment, provide nonslip paths, block unsafe stairs and assist with walking if directed. Do not give human painkillers or sedatives, which can be dangerous or worsen instability. A dog with a possible spinal injury should not be pushed to exercise.
Know the emergency signs
Prolonged or repeated seizures, collapse, inability to stand, sudden paralysis or difficulty breathing requires emergency care. For additional details see neurologic warning signs and treatment options.
