Honestly you could put some kind of strong smell on your side of the fence that would stop the dogs from smelling the dogs on the other side of the fence.
On a more funny answer, you could use electricity on the other side of the fence, not anything crazy just enough to deter.
Never thought about a smell thing. I’ll look into it, thanks!
No problem I literally just thought it up. I have no evidence it would work but I know dogs are very sensitive to smells so it would make sense to me anyway.
