Three of the most important commands are COME, then SIT, then STAY. If done correctly , one can get the resulting photo of two dogs waiting for a snack. But unfortunately that result is not common enough. It takes a lot of work and constant bribes to train up a dog.
I remember when Katie was an infant. Her grandmother got a puppy when she was two weeks old. I remember going with her and Maggie to pick up Bridget number 1. And we worked hard at the commands of sit and stay. Katie grew up with the puppy. We all have fond memories of her walking around the yard at Grandma’s house holding a cookie above her head. That was the only way she could eep the dog from eating it.
By the time Kate a year old, she had those commands down solid. Coming out of a grocery store, I would place Kate at the curb an say “SIT” and “STAY”. It was wonderful, the kid was safe while I put groceries in the car. Other people were not so impressed. I remember one woman telling me very indignantly “That is a baby, not a dog. You should be ashamed of yourself”. Wish I had been quick enough to reply “Really, that’s a baby? I was ripped off, the breeder told me it was a golden hair pup.”
