<human>: Hey reddit, I need a little help with a situation that is happening in my home between my younger dog and one of the oldest. Here's the deal, I have 5 dogs. the youngest one just turned a year old and is a male, and the oldest of the group is 12 and a female. this is where the problem is, The youngest one keeps attacking the old female for no reason that I can observe. she just walks into a room, any room, and he will immediately Bogart her. He doesn't always attack her, but if he doesn't, he just stands really close to her in a very dominating pose. as I'm writing this, she just walked into my living room, and the younger one immediately growled at her, so she walked the other direction. It's really pissing me off, she's like an old lady! He doesn't do this with any of the other dogs.I know he has some sort of dog logic behind this and isn't just being a little dildo, but idk what it is or how to make it stop, i thought maybe it was a dominance thing, But I don't think she is the alpha? and she's female? I don't know. any advice on how to handle this situation? He doesn't actually bite her or anything, so he's not hurting her, he's just being a dick. I don't know what to do.

Provide a brief overview of the text.
