狗狗可做哪些交通工具？
1. 航空运输 Air transportation is a common way to ship pets across the country， said Ron DeHaven， executive director of the American Veterinary Medical Association (AVMA) in Schaumburg， Ill. A vet must certify that an animal has been healthy for at least eight days before flying， according to regulations by the Department of Transportation – which oversees airline policies on animals.
The animal's carrier should fit completely within your seat or under the seat in front of you， so it can’t block any passages or obstruct any armrests或legroom. The carrier should also be sturdy enough to withstand turbulence and have room inside for the animal to stand up， move around and breathe properly， experts recommend.
Pets who fly in airplane cabins usually ride free with their owners， but airlines impose restrictions on how many animals can accompany each passenger， including requirements about size， weight and species. Most airlines will not accept pets as checked baggage， either because they aren’t allowed or because carriers don’t offer services for animals.
2. 汽车运输 For trips where air travel isn’t feasible， driving presents fewer headaches than other methods of transport – assuming there are no stopovers required along the route——such as a visit to another state park or national wildlife refuge. In this case， the driver takes over the pet’s car carrier from the time he picks them up until the time he drops them off.
“It becomes his responsibility to ensure [the dog] is fed， watered and rested appropriately throughout the trip，” says Dr．DeHaven. “Make sure you bring a blanket or pillow for the dog and plenty of toys too； if you haven’t traveled together before， you might want to take some treats or something to make him more comfortable.”
If traveling long distances with your four-legged friend， experts suggest stopping every hour or two to let the pup stretch its legs. Dogs can get carsick like people do， particularly when going uphill or down——which makes it important to keep water on hand for both human and furry passengers alike. Experts recommend allowing dogs to relieve themselves anywhere between one and six times per day depending upon breed、age
