I'm trying to decide where I should go from here- to a drag line or a tether? Jake has gone back to redirecting his aggression onto dixon if he's upset about something going on outside (like the neighbor's cat baiting them through the front door or a stray dog in the front yard). He also just started doing this when we're all out in the back yard and I'm throwing the ball with Jake. Dixon will just be lying there and on his way back with the ball, Jake seems to think it's necessary to come and growl at Dixon. If I'm standing next to or over dixon, jake won't do a thing, but if I'm not close enough he'll bark or growl at dixon. Dixon will put back his ears and drop down in submission. This has to stop- Dixon shouldn't have to cower. I've started taking them out separately to avoid this.

I assumed the drag-line would be better so I could correct Jake before it escalates. If he's on a tether he never does this. While avoiding the behavior with the tether is good, it isn't fixing the problem... am I correct in going to the drag-line?

Also-- the drag line I fasioned is an inexpensive nylon lead with the handle cut off... how long should this be ideally? I have a tiny house, and the 5'-6' length just seems too long; Jake seems to be stepping on it. Ideally I would be able to step on it if I needed to though, right? So it should at least hit the floor?

Is it correct to attach the drag line to the prong? or to a flat collar? Is clipping the drag to the prong dangerous in the house?

Thanks for any thoughts-
