If you notice your pet banging into objects and becoming disoriented on walks it may be going blind. Many owners find this very upsetting but your pet will have learnt to adapt to its diminished vision. In fact many owners only find out their pet is blind when they move house or take it in holiday! If the lens of the eye becomes cloudy it could be getting cataracts so take it to the vet for an eye check. Cataract surgery is now readily available although it can be costly. However most blind dogs lead very happy lives as have a very acute sense of smell. They also don't have to watch TV or read the newspaper like we do!
