If a dog attacked you, but did not bite you (you managed to drive it away, for example, with a stick), then you do not even have the opportunity to complain about this attack to its owner: since there is no damage, then there is no crime. If you killed a dog that attacked you before it had time to bite you, it will cost you the same as damage to someone else's property. In addition, you will have to answer for carrying weapons with which you damaged this property. And if a dog bites you to death, the owner will receive a maximum of 2 years (!!!) in prison...
