We came across this interesting product today, a spill-proof bowl for dog travel. I'm interested in hearing if anyone else has used it and if you've found it to be successful? As you can see from the video below, it looks like it can withstand quite a bit (including a pretty bumpy car ride!). It'd be great if someone could engineer a similar bowl that would attach to crate doors for air travel. The reason this would not really be suitable for pet air travel is because the airlines require bowls to attach to the inside of the crate door, so they can pour water in through the door. However this bowl looks like it could work quite well for ground transportation when shipping pets! Purchase it for $25 USD on FetchDog.com here.
