Dachshund air travel can be an enjoyable experience, as long as you keep a low profile. Can you see me here at Paris Charles de Gaulle airport?
Probably not, and that's exactly my point. It's best to stay in your carrier, but you can use your judgment and stretch your legs in low biped density areas.
Be sure to avail yourself of complimentary in-flight entertainment options, especially if dogs have prominent roles. (The movie below is "Absolutely Anything".)
And here's me with Mom and Grandpa at the Spokane airport, en route to my Idaho home.
All of this was in late July; I've been in Idaho since then. It's a working vacation because I'm on a mission to evict the resident rodents from the house. My mission requires the adoption of a nocturnal schedule, which is sometimes at odds with Mom's. There's not much I can do about that.
