I have heard of backward sneezing, but thankfully, none of my dogs do it. I think your only answer is to check with your vet, although I'm not sure if there is anything you can do. Good luck!!

Have we seen a picture of your Daisy? If you posted one, I must have missed it. I love those Flat Coat Retrievers.....sort of like a black Golden. We refer to them as "Boldens". I've never seen one in person, but I sure would love to. I'm assuming that personality and size wise, they are similar to a Golden Retriever or a Lab.

Hugs to Daisy!
