kodie has the same problem!! he loves kids,and loves to lick them,jump on them etc.but he scares them when he tries to jump! i Tell him no and he still does it.When visitors come over i have kodie on a leash so he doesnt jump or run up to them.he does it to people when we stop and talk to people on the walkway,and im using his choke chain,which it stops him from jumping,but i dont want to use it too much,i honestly(spl?) dont know what the correct thing to do for that problem.
