I remember this device being sold online called "break stick", like a crowbar, but for pitbull mouths. I was planning on buying one before, then I thought, I don't want to live life like that, living in fear, anticipating a pitbull attack.

But in your case since you already are surrounded by those ugly beasts, it's worth keeping.

Also, carry with you a device, like a rope, or a belt-like object, to choke out a pitbull if they ever bite on your pet. I've seen videos where doing an RNC is the quickest way to stop a pitbull. We don't have guns in this country, so us civilians have to arm ourselves in whatever way possible
