Not all agressive animals have rabies, Racoons are aggressive, atleast here in Maine they are. Young coons actually play this way and other ways to become adults. Like your dogs and cats play, dogs growling and cats sidling towards you and hissing. Here in Maine anyways, if something is in the yard, even a larger dog, these guys are learning to make their area free from preditors, any dog is a preditor. Momma could have been around, up a tree or watching sleeping off the evening before and these guys went out on the town like a gang thugs.
With a dog urinating and what not around the place, it isn't a big deal, if you go out around you will find black tarry seedy scat where they marked their territory.
Animals are strange, your boxer could go out and kill a coon and never before done it, and a coon could wipe out your hen house, garden, plant pots and put hand prints on every window because you don't have anything that they fear. Now, you put a coon dog on a run and your never going to see the coons again until you get rid of the dog.
Call AC, probably nothing can be done, call the game and wildlife in your area and question the behavior and what to do. If they say nothing can be done, quietly and appreciatively say thank you and get a trap, shoot and burry the critters. End of fears. Like I wrote earlier, 2 or 3 immediate shots with a .22 at the base of the skull and walk away, wait a few hours before touching, making sure its dead and cooled off, move trap with gloves on, dig a DEEP hole so your own dogs will not dig it up and say no more.
Set another trap the next night and carry on. Tuna fish with liquid in the can with the cover off, close and secure the one end so it has to go into get the can of tuna (if its a 2 end trap, raise up or use a couple bails of hay or fence to prevent your poochies or skunk in the trap.
PS- if you get a skunk, it can still spray in the trap, also Lever 2000 will remove the skunk smell from your body, trust me...I know
