I've read alot about this topic and as a victim a blind man could see the true problem. Irresponsible pet owners. I know some don't agree, but accountability is the issue. Say you continuely catch your neighbors dogs leaving "gifts" in your yard. This is not a 1 time issue. Dogs relieve themselves in the same place because of habit and marking and lack of a clean yard at home(owner doesn't pick up waste) I have heard every excuse in the book. Bottom line is an excuse is a lazy reason for not doing something right the first time. Aka Laziness. The best excuses are=how do you know it's my dog/dogs? my dog/dogs never run loose/out of their yard, if my neighbors who have NO pets would fence in their yards my dog/dogs wouldn't roam loose, the list goes on and on. we are in the middle of spending OUR money to repair our neighbors fence, (who by the way has NO pets) to keep his next door neighbors dogs out of our yard. Is it fair? Abseloutely not. But this is the only way we can enjoy our property in safety. The dog owners have aggressive dogs. 2 of their dogs chased me in my own frontyard! Witnessed by another neighbor. Call the Humane society you say, we did. as soon as the Humane officer left they were pounding on our door throwing a fit harassing us. Thank you Humane Society for keeping your complaints confidential as to who the complaintant is. Once again the responsible people have to take on the responsibility of those irresponsible. Only in America!
