I have an airline approved kennel. When mine travel in the car, the kennel gets bungie cord fastened down to keep them as safe as possible in case of an accident. Kennels are very important to help in house training. Dachshunds will likely have some kind of back issue over the years and it's very important to get them comfortable being in a kennel because managing a back issue means a lot of crate rest.
When it comes to fashion, we've got a lot of harnesses for all seasons. That's really were mine will shine. lol
