The right transport: a small covered carrier
A Khaki Campbell travels to the vet in a small, well-ventilated pet carrier, not in any kind of trailer. This is a light laying breed that startles fast and flaps hard, and a carrier sized so she can stand, sit and turn around is big enough; extra space only gives her room to throw herself against the sides. A light cloth draped over the top keeps the carrier dim, and a dim Khaki Campbell sits down and goes quiet instead of tracking every movement outside the door.
Lining the carrier for duck feet
A Khaki Campbell's feet are built for soft ground and water, not for slick plastic or wire. Line the carrier floor with a folded towel or a layer of clean straw so her webbed feet grip instead of splaying, because a duck that slides at every corner arrives stressed and can strain a leg. Skip loose shavings that puff into the air vents when she flaps. If the trip is long enough that she will soil the lining, pack a spare towel so she is not sitting on wet bedding for the ride home, and never put a water dish in for the journey itself, since even a shallow one ends up tipped across the floor.
Catching and settling a flighty layer
A Khaki Campbell is quick on her feet and quicker to panic in a corner chase. Herd her gently into a small pen or the duck house first, then lift her with one hand over the wings and the other supporting her body, holding her close against you so the wings stay folded. Set her into the carrier facing the back corner, close the door before you loosen your grip, and cover the carrier straight away. Chasing a Khaki Campbell around a full run right before a car ride teaches her that hands mean trouble, and she will remember it at the next catching.
In the car: level, cool and quiet
A Khaki Campbell rides best with the carrier wedged level on the floor behind the front seats, where it cannot tip or slide under braking. Ducks overheat quietly, so keep the car comfortably cool and never leave the carrier in a parked car while you run an errand on the way. Soft radio and calm voices are fine; a dog barking from the back seat is not, so travel pets separately where you can. Two Khaki Campbells that live together can share a slightly larger carrier and usually settle faster side by side than either would alone.
At the clinic and the trip home
A Khaki Campbell should stay in her covered carrier in the waiting room rather than being held, since a busy room full of dogs is exactly the stimulation the cover was blocking. Lift her out only when the vet is ready, supporting her body the same way you did at home, and let the clinic know she is a laying duck so her recent laying pattern can be part of the conversation. Once home, set the carrier inside her run, open the door and let her walk out to water in her own time. Travelling with her laying notes and any past treatments gathered in KinsLe's Pet Passport means the vet can spot a change in her pattern without you reconstructing it from memory.
