Attacking dog deterrents

Hey hey. Me, my husband and two small children bike regularly. We were charged by an aggressive dog, thank god we were able to outrun them. I’m looking into what to use as a deterrent and I find this guy on YouTube, big Tex amputee who bikes around the world. After watching several videos of his I would feel very confident using whatever spray he uses to deter attacking dogs. Problem is, I have no idea what he’s using. I’ve read comments and cannot find it. He refers to it in the videos as both bear spray and pepper spray. I’m looking at the Sabre protector dog spray, but have a hard time being sold on one that shoots a thin stream. (Dude in the videos spray is pressurized, and shoots a cloud) I think the sound also scares the dogs as well. I want to feel 100% safe, but I just don’t feel confident in trying to nail a dog directly in the eyes, while one handed on a bike with a thin little stream. Maybe I just don’t have a good experience.. we recently had a dog fight at our house and the dogs were going to kill each other. We pepper sprayed them with regular ole human pepper spray and it did NOTHING. Plz dont reccomend an air horn or pressurized air can. I need the first option to WORK, cause the second option is my .380. And I don’t want to have to use that option. Thoughts?
