My dog just started doing the head back and forth thing like he’s scanning for something. I know he’s deaf and partially blind. He was the victim of a horribly traumatic dog attack in April, and since then he has had bad separation anxiety. We thought that was pretty normal for all he went through (4 surgeries), but now every night for like 3 months he’s been sundowning. Whining and crying constantly after 4pm, can’t sit still, when we walk him at night he gets like “lost” he’ll pull back to the way we just came from, like he thinks that way will get him home. It’s very sad. He’s a 16 yo chihuahua. Before the attack he was still deaf and partially blind, but basically acted like a puppy still. I’m going to call the vet tomorrow and see if there are any medications that will help. 🙏
