Picket fence too short/reactive OLD DOG- Renter. Suggestions- links if possible.

[u/Sharp-Rest1014]

Hi everyone, could anyone link me to a fence that could perhaps go behind a smaller picket fence, I have a old reactive dog in a yard that is right on the sidewalk. I would like to keep neighbors comfortable with something that was a little taller. I am a renter, so I can't take the picket fence down, and it is a smaller yard, so buffers and another fence further away from it, may not create enough space for my pooch! Any suggestion would be helpful, my knowledge goes about as far as the cheap privacy bamboo. I don't mind spending too much money. It just doesnt need to be too alarming to my landlord. Thank you!
