Hello Anna,
Thank You for the question, and more importantly, A BIG GIANT THANK-YOU for fostering a pet. Especially for fostering an older pet. Without people like you many rescues, and many rescued animals would never have a second chance at finding a loving home. It takes a very special person with a very big and generous heart to take a pup in need of so much assistance. I applaud you for not only being courageous enough to foster him, but also for seeking help in understanding how to best care for him.
Because I am a veterinarian I would recommend that you first address and understand all of his medical and health issues. Your veterinarian can help you assess the degree and cause of blindness (sometimes it is due to a treatable disease and therefore the blindness can be corrected), and the ears should be examined also. In an older dog I would check for glaucoma, infection, retinal damage, and any other age related changes like osteoarthritis, joint disease, etc. A thorough examination will help you understand his needs both now and in the future.
Next I would recommend that you think about his world from his perspective. He is likely unsure and a bit afraid of his new environment so it is logical for him to just sit still when he encounters an obstacle. Can you imagine being blind in a new place? I know I would be afraid of falling, and bumping into things. So I would first set him up in a small area of a very safe place. I would make that place a place where you intend him to spend most of his time. Be very careful of any sharp edges, like chair or table legs, and I would spend as much time with him in this place as possible. So that he can build a mental picture of the layout of his new environment with your encouragement, support, and guidance.
Once he is comfortable there I would very calmly, slowly, and gradually open him up to other very small areas of the house. But remember once he is comfortable navigating around one area you can’t change the floor plan. So the furniture should stay in its original location to keep him from getting lost and confused again.
Most blind pets are very quick learners once they are comfortable on their environment. If your dog has been through many households he may just be so confused that he has given up trying to learn his territory. Or maybe he has other impairments that make him reluctant to be adventurous?
My best piece of advice is to be very calm, gentle, and patient.
I wish you the very best of luck!
Sincerely,
Krista
Hello,
I think your dog needs to see your vet ASAP. It could be many many things. Too many to guess. I think that an exam, bloodwork, urinalysis and blood pressure are all indicated. After all of these are addressed y’all aboit cognitive dysfunction assessment.
