Don’t move the furniture.
Actually, dogs can get around fairly well by sense of smell in familiar surroundings. We have a blind dog and a close to blind cat. As long as food, bedding and furniture stay put they typically can get around the house and the backyard just fine. However, here is a list from a handout on dealing with blind pets:
“Here are some ideas that will help you and your pet adjust to its blindness sooner.
1. Your pet doesn’t need to be put to sleep just because it is blind.
2. Don’t re-arrange your furniture if your pet is mostly indoors. If your pet is an outdoor pet, don’t plan major landscape projects!
3. If you have a hot tub or pool, a cover or barrier is necessary. Your pet could fall into the water, not find the sides and drown.
4. Don’t let your pet play in traffic. If you have an outdoor pet and no fence, please check into an “invisible fence”.
5. If you live in a house or an apartment with a balcony, be sure that your pet cannot walk between the vertical supports and fall to the ground. If necessary, plexiglass should be applied or the vertical supports modified to prevent your pet from getting through.
6. Feed your pet and keep its water dish in exactly the same place each and every day. Also, try to have your pet sleep in the same area on a routine basis. These areas will then become reference sites if your pet becomes disoriented.
7. If your pet gets disoriented, take him/her to its bed or food bowl. This will be a land mark that will re-orient your pet.
8. Put your chair back under the table after meals. Things that are left out will cause your pet to bump and lead to disorientation.
9. Until your pet learns about stairs, you will need to place a barrier to prevent him/her from falling down the stairs. The same is true for stair landings.
10. Most clients remark that going up and down stairs is the most difficult of all things to “re-learn”. Be patient, your pet is trying to do its best.”
