On a post somewhere Karlin recommended www.dogjaunt.com for travel tips on in plane carriers. I have been looking through the site and it is fabulous but not just for traveling by plane - there are some great product recommendations, travel by car tips, ideas for successfully taking your dog to friends homes and many other tips. I have really enjoyed this site and thought I would make sure you all knew about it - Chloe the dog they travel with is a Cavalier too!
