@Averbonus,
Dogs don't like cones, but they do prevent the animal chewing or licking the wound - and that is essential for the healing process to take place. Different dogs react in different ways - the best thing you can do is to try and keep the animal occupied, with chews, toys, and lots of attention. There are soft cones advertised, but I don't know how effective they are - perhaps your vet can advise you about them.
Good luck, I hope your pet makes a quick recovery.
