From what I heard when we moved here about 3 years ago, they have had several dogs before these shot by neighbors because they are obnoxious pains in the behind. But we live out in BFE and they have about 33 acres so they think they can let them roam at will. We have 3 acres, and the dogs seem to think that my 3 acres is their 3 acres. I know she must have got in trouble last year for them attacking the bikers because she did try an invisible fence but the stupid lab kept going over it and screaming so she took the collar off and tied her up for a while. But then it was back to the same old same. She said she is used to running free and couldn't confine her, it would just break her heart. Really?
I have 6 dogs, but we have a fenced backyard for them. If they are out of the fenced area the Great Pyrenees is on a lead line and the others have the sense to stay with us. But they are never allowed to roam at will, unsupervised. Funny thing is, when we are out front, her dogs come charging over at us, barking and trying to intimidate us. If you yell at them the go home for the most part, but usually not before taking a dump on the property, kinda like a screw you lady from her dogs.
I love dogs, really I do, but on the owners property. Heck, I wouldn't have the amount I do if I hated dogs, but mine do not predate on the neighbors sheep, goats, cattle, etc.
