A helpful article on living with a blind dog from PetPlace.com.
andBecause the senses of smell and hearing are amazingly well developed in dogs, they are much less dependent on vision than you would expect. For this reason, their behavior may return to almost normal once they adjust to their blindness.
Among other things, blind pets strongly rely on their memory to help them navigate through your home. The most important thing you can do for your dog is to keep things in the same place at all times. It is important that you be consistent.
For example, don’t re-arrange your furniture. Pick up after yourself and instruct your children to do the same. Keep his normal path clear and don’t leave things lying around that your pet can “bump” into. A misplaced laundry basket or pair of shoes or a toy can be a problem for your blind pet.
Return things after you move them. This includes chairs moved during dinner or furniture moved for visiting company. Pets can bump into these objects easily, and this can cause injury or disorientation.
Maintain a consistent area for eating and sleeping. Keep your pet's bed and his eating bowls in the same place. This is especially true for his drinking water. Do not move these areas.
Place barriers over hot tubs and around pools.
Remove or cover any sharp objects or edges, particularly those at eye level to the animal.
Block your pet’s access to the fireplace, open stairways, balconies, decks and other potentially hazardous areas.
Make sure your pet is well identified. A collar and microchip are critical if your pet becomes separated from you. If lost, a blind pet will probably not be able to find his way home.
Identify your pet as being blind. Place a medical alert tag on your pet’s collar that says that he or she is blind, and include your contact information
