My dog was always independent. She loved having the freedom to hang out with us on the couch or get up, and walk to another room. Sometimes she left to go take a nap in a quiet spot or watch the front of the house for the mailman.
When she lost her eyesight from diabetes, we took extra care to guide her around the house hoping to keep her confident in her independence. We didn't move furniture. We kept to a routine hoping to effectively manage her expectations.
But, because we actively changed our own behavior, it was clear that our sweet dog wasn't getting lost in a room because we left an ottoman in her path or moved her food bowl. Her behavior wasn't related to not being able to see, she was dealing with doggy dementia, also known as Canine Cognitive Dysfunction.
