Hi! My name is Susan, and I am owned by a 2-year-old Deerhead Chihuahua. Zoe has been coughing and sneezing lately, and I don't know what to do. She saw the Vet 2 days ago, is healthy, no fever, shots up to date. But, my little girl is still not feeling well

Any suggestions? She weighs 9 pounds, and is that rare, floppy-eared Chi
