A dog obstacle course requires items to jump over, run through, and run around. For the course you can use tires or hoops for the dogs to jump through. Ramps leading to raised platforms with a second ramp leading down work well. Attach a non-skid indoor outdoor carpet for safety. Weave poles can be fashioned from PVC pipes securely placed vertically in the ground. Large sections of pipe can be used as tunnels for the dogs to run through. Building frames for adjustable height jumps will be useful in such a course, as well. A seesaw is simple to build yourself, again with indoor outdoor carpet attached to prevent the dog from slipping.
