Rehoming lab/dane mix in Pineville, Louisiana For Sale

Rehoming lab/dane mix. He's black and weighs about 80 lbs. He lives with our two other dogs and does well with them. We just don't have the room for him to get all the running and exercise he needs and I don't have the time to run him every day. He would love a very big fenced yard, not chainlink since he can jump that. He is protective of the house and backyard. Has never caused an issue with my 3 young nieces (7, 5, and 3) other than being in their way and swiping their food. SERIOUS INQUIRIES ONLY- I have already had 3 people not show that were supposed to come meet him.
