Until you can get the animal to a vet, Please also try these things, that have worked for me in the past :-

Warm salty water or saline solution (Use cotton wool or a small plastic tub)
Wash the wound out with this either by flushing the wound or by soaking (depending on the location of the wound)
This helps to kill the germs and if the wound has maggots in it, the maggots will drop out

Fido Wound Spray (RM10 at Carrefour)
This also works wonders but while the medicine doesn't hurt the animal (the animal doesn't seem to be in any pain when the stuff is sprayed on a wound), the sound of the spray will make them bolt and scratch you in the process. So please be careful!

Good Luck!
