I don't know what the charges could be,but when a dog came on my property and was biting my dog I was kicking it and hitting it.I did not give a crap about the dog.I threw my bloody dog in the car,and yelled to the owners I would be coming round with a bill.
Me, I would have beat the dog and then present the owner with the bill.
I think you can file a report(get her a ticket) on a loose and dangerous dog. I am sure the dog snapped at you.The one I took on did. Also, present the owner with bills for the dead ones,and the medical costs ofr the roo. I would do all I could not so much because of the dog,but because of the owners reaction.Her response was so lame. The owners of my dog attack paid the medical bills.This lady sounds like she will not want to pay a dime,and will blame you for the incident because you have animals that intinced her large dog.
Oh I just saw the responses,so I am glad you got her to pay.Hope there is no next time. I told the owners of the husky biter I will attack to kill first since I know their dog bites.
