i would not panic, just treat the dog like a person -
do not pet them if U are coughing + sneezing, cover Ur nose/mouth with a Bent ELBOW not a hand, when U cough or sneeze, wash hands often, and after Every Time U blow Ur nose.

a mask is not very effective with flu-virus, even the fine-particle masks are a bit too coarse to filter the flu. but good handwashing + basic hygiene work well.
cheers,
