Ive been thinking about getting something for my lab to jump over in the yard just for fun, cuz we put grass seed down and put up a lil foot tall fence to keep the dogs out but she loves jumping over it, lol. Should i just have my hubby build either a wood or plastic pipe thingy to jump over? I looked on ebay and they are kinda spendy. I think even Red would like a tunnel or something to run through, any ideas on where to get a cheap one? Or how to make a tunnel?
