Oh man... do we ever! Our three dogs love the kennel (aka "Puppy Prison Camp") but as soon as we leave the quiet in the car is almost always too much for us.
We're leaving for two weeks next month and we're dreading this trip because of our pets... or at least one of them. In October of last year I planned a trip to WDW to propose to my then-girlfriend. The week before the trip our boxer, Charlie, got very ill and had a stroke. He spent two days in the vet ICU and another three days at home hooked up to an IV pump. I slept on the kitchen floor with him so I could keep an eye on him and give him his shots/change his IV bag. We rescued him in Feb. of last year and found out pretty quickly that his poor little heart is in bad shape. The vet gave him six months to live at that point, so the stroke in October was almost six months to the day that news was broken to us.
He's doing well now and, in fact, is healthier than when we rescued him. We've put him in the kennel for long weekends with no problems (lots of guilt though), but this upcoming trip and the anniversary of last year's crisis are looming large.
