Jasper is nearly 15 months old, and his pulling on a lead is getting worse. He did go to puppy classes when he was little and wouldnt walk there. I have tried the walking backward technique, a harness, a halti, a extendable lead. He just hate all leads. He will walk great off a lead, happily walk along next to us, but put a lead on him...I am unable to walk him myself as he pulls so bad, and he has been known to pull me over :doh:. Does anyone have any advice or can recommend a harness that actaully works and lessens the pulling? My husband and I work on him everytime we are out, but nothing works. He just hates leads. It is making walking his an unplesant and frustrating experience, for me, my husband and my other dog (who does walk lovely on a lead). Any advice would be greatly apreciated!
