In Michigan if you have any hoofed animal you can legally shoot any dog that comes on your property...I followed a big Shepard type dog that had been on our property several times...didn't know the dog or who it belonged to, but carried a gun when I went to the farthest barn from the house...happened to see him one day when I was sitting on the porch, got into the car and followed the dog home (as he trotted down the middle of the road) He turned into one of the homes about 1/2 mile from my farm.....I pulled into the driveway and tooted the horn for the owner to come out...when she did I asked her (while staying in my car) if that dog was hers, she said yes......
I was so ticked off at the dog and owner I wasn't sweet, just told her the dog had been on my property several times, I have a flock of goats and I can legally shoot that dog if he is on my property again..Rolled up my window and backed out of the drive way.....she got the message and I didn't see the dog running anymore but was usually chained to his dog house, then one day he just disappeared....It wasn't me, but several neighbors had cattle and were equally POed at that dog.....
