I am taking a trip to alabama in mach, I want to take my chiuawua and Im not

[Mrgoodtimes]

sure about her breathing? We had her checked out and X ray'd and they said she def does not have the collapsing esophagus, they said what she does is a reverse sneeze. And believe it or not I taught her how to control it with a sort of meditation. She only does it now under harsh conditions, like if I go on vacation she gets way overly excited when i come home. But i know the air is thicker in alabama and mid march is approaching spring so Im also concerned about polin and stuff.
has anyone here ever taken their Chihuahua to the south? Do they even have Chihuahua's down there?
