If the dog is injured on a walk, the owner suffers too. But keep calm and look after your pet straight away, then the worst can usually be prevented. This is how it works:

Cut away the fur

Use nail scissors to trim the fur about one centimeter around the wound.

Remove foreign bodies

Carefully remove thorns, splinters or shards etc. with tweezers.

Clean the wound

Dab the wound with sterile gauze or a clean, lint-free cloth that has been soaked in a diluted, lukewarm disinfectant solution. Then dab dry.

Keep clean

Protect the wound with a bandage to prevent secondary bleeding and the ingress of dirt.

Incidentally, you should also consult a vet so that your pet can be given antibiotics if necessary and the bandage can be checked.
