You are not alone. Gigi will only sit and down on soft surface. I have to brought a towel to puppy class otherwise she would just stood there and look at me. As for "stay", I am all confused with "stay", "settle" and "wait"...haha... and I think she is confused. She is smart, but she doesn't have too much patience and she is VERY food motivated and I think sometimes she pays too much attention on the food and forgot what we are doing.
We are going to take clicker class when she is done with puppy class.
Umm... I guess I am not too much help, sorry.
