Dog Glider
Dog flies a glider, it launches by sliding down hill.
Dogs can ride snow sleds and control skateboards. (see links)
They should be able to fly gliders as well. Basically a snow sled with wings.
I'm also thinking it might be possible for them to get a rolling glider up to speed on a flat surface, jump on it and shift their weight so it aims the wing equipped skateboard up long enough to do a short glide.
No ailerons, too heavy, just the twist wing control surface like the Wright Flyer used.
Now you'd probably need the pooch to launch into a good enough headwind but it would be flying dogs, which is after all, the goal here.

只是想象起来很有趣。
我猜有些品种的狗又小又快，可以自己抬起来，但翅膀可能会阻碍加速，所以，我们可以让翅膀在记录到一定风速时展开，当举重变得消极的。
所以，我正在想象一只狗在达到适当的速度时会自动展开翅膀（可以使用充气活塞轻松完成，这会释放空气以缩回，小型电池和泵可以恢复压力）
Just fun to imagine.
I guess some breeds of dogs are small and fast enough to lift off all on their own, but wings would likely impede the acceleration, so, we could make wings that expand when certain windspeed is registered, and released back to normal when lifting weight becomes negative.
So, I'm imaging a dog that expands the wings automatically, when reached appropriate speed (could be done easily with air-loaded pistons, which would release the air to retract, small battery and a pump could restitute the pressure)
