How to carry an injured dog
Use a pet carrier if possible.
If you have a pet carrier that you can safely place the dog in, do so. This is the best option to protect both you and the dog.
Encourage it to lie down, and support its body with anything soft to minimize movement during transportation. For more significant injuries, or in scenarios where the dog is having trouble breathing or is unconscious, you'll want to move it as little as possible.
