my yorkie Sonic does this, so what I did was put a small step stool I use around the house by the couch so Sonic can use it to get on the couch..*he used to use the step stool all the time*  Mind you Sonic can jump on the couch he does it all the time, well few days ago sonic barks wanting on the couch, I go to pick him up and he runs so i go get the step stool for him put it by the couch, what does sonic do?!? he sniffs the stool and jumps on the couch without using the stool, I was like Sonic! and started laughing. So even though he can jump on the couch, he barks to get on the couch and runs, he is getting better about running from me, he starting to rare up on the couch for me to pick him up..     |
