Vestibular disease. A very common cause behind a dog losing their balance is vestibular disease. Vestibular disease is a problem deep in the ear (inner ear) – an older dog is more likely to develop vestibular disease than a young dog.
Brain. The brain controls most of our body, if it develops a problems such as an infection, inflammation, an injury, a bleed, a blood clot, seizures or a brain tumour, your dog is likely to develop many symptoms, including loss of balance. Some puppies are born wobbly because of a problem with the balance centre in their brain (called the cerebellum).
Spine. Spinal fractures, infections around the spine, inflammation of the spine and slipped disks can cause paralysis – which, depending on how severe it is, can look a bit like loss of balance.
Other. Weakness in the legs, eating something poisonous or having a reaction to a medicine (some antibiotics) can all cause symptoms that look like loss of balance.
