Great but could be bigger

I travel a minimum of twice a month and both dogs always go with me.  Since most of the trip is spent in the vehicle, I have been trying to find ways to minimize the stuff I take and the room that stuff takes up.
These bowls are perfect for this.  Not only do they take less space when packed, they also fit nicely in the "must be able to access on the road" bag so I can ensure I always have a water bowl easily available during the ride.
I do wish they were a big wider.  My small dog doesn't have any problems regardless of the level of whats in the bowl.  My larger dog isn't as lucky.  For him, I need to make sure the bowl is fairly full to make sure he is easily able to reach the contents.
