I have three dogs and up until last year, they were never any problem. Last year, a man moved into the house next door with a very aggressive dog. His dog never showed any aggressive behavior towards people, but when my dogs were out going to the bathroom, his dog acted like he wanted out to kill them. Instead of taking my chances, I quickly contacted a fence contractor and had a part of my yard fenced in for my dogs. I looked through a lot of fencing options to find one that would be able to keep my dogs safe from that other large dog. See what I found out right here on my blog.
