Depending on the size of your dog, the normal ear hats work pretty well.
They did for years.
The largest pet section (perhaps the only pet section) left is at WoD in DTD. I don't know if they have ears, though.
That stinks! We always bring back something for our dogs ! They've gotten the ID tags and food dishes in the past. Does anyone know if you can still get the ID tags? We need new ones with updated information on them!
I actually observed this on my last trip- somebody had put a kids' size ear hat on their service dog (yellow lab, if that helps for size comparisons). It was really cute to see everyone in their group, even the dog, wearing ears.
They had ID tags at MK when we were there in December. They were over at the Fire Station right inside the entrance on the left.
