:( Ughhhhh...having trouble

[joycenalex]

my friends belgin malios cross would jump on people at the door, so kyla got in the habit of placing the halti and a short lead on her when some one knocked (there was a note on the door explaining that dog training was in progress, so be patient with the door opening). when the visitor knocked, freya would run to the door baying like a hell hound, kyla would take the short lead in her hand and have freya sit before kyla would open the door to the visitor. if freya didn't jump, the visitor would give her a treat(a puppy cookie, really small, just a taste really). after a few minutes kyla would remove the halti, lavish praise and so it went. freya still bays like she's coming through the door to rip out your throat, but she only sits now.
and the suggestion about the whole family using the same word for the same command is dead on right. good luck, i respect your plea for help, you're brave in asking for it.
