If you can manage to have the mutts caught, prosecute them by legal means. Stay in touch with the prosecutor and let them know that you wish to be heard at sentencing. Let the judge (and jury) know that the vandalism has taken food from your table due to the mutts disrespect for the property of others. Let them know how hard you've worked for what you have.
You'll feel alot better having had your chance to speak, the mutt will be there while you look him in the eye and you can sleep well knowing that the law isn't looking for you because the mutt reported you for assault- and he will.
