Just wondering if anyone out there knew of any company that carries fun dog print carry on luggage. Like a med sized carry on bag.

Check out the Weathertop Collection....somtimes they have travel bags with a Labrador print.

Funny you should ask: I was just on divine k-9.

In addition to the Spode Lab items,
I noticed the Sydney Love collection.
I have seen it at specialties, and folks seemed to like it, even though it is not high end luggage, just fun!

Have fun!
