I know some of you are in the same situation I am; no fenced yard with a young Beagle! Henry loves walks and is really good on the leash, but he needs to run sometimes. I take him to parks, baseball fields, basically anyplace I can find fenced in! I live out in the boondocks,though, with lots of meadows and pastures around, so I usually put the harness on him with a long line and let him sniff, run, whatever. Today I tied a small log (about 8 pounds) to the end of his long line, and it worked great! He was able to run and pull the log, and I was able to stay beside him without worrying about the line burning up my hands! Just thought I'd share.
