Exactly. I hired a fence company to come out and build a fence around my in-town property because my elderly neighbor’s son or grandson keeps pits in chicken wire coops or on short tethers on her property. The fence company owner was accompanied by his wife...who showed me the scars she had gotten when being attacked by pits while doing a fence estimate in a more rural area near hear. Her husband came out, wrestled the dog off her and then shot it dead.
We installed a 6 foot chain link fence around our in-town property so there wouldn’t be any issues with out Doberman. Good fences prevent problems.
