I also have dogs that come on to our property 2 labs and other big dogs. i don't know who the onwer's are but every time we see them we scare them off but they come back and i'm wored cause i have 3 cats that are inside and outside cats and since we have dogs ( that are trained to never set a paw off our property and are always keep an eye on) there not scared of other dogs thinking that a dog is a dog. then i get chickens i'm putting eletric fance around both the coop and the run so hopefully nothing will get in!
