With my new furbaby, I had my boys constantly ring the bell and everytime I had him sit, when he obeyed and remained seated he got a treat. Boss greets everyone sitting and licking so that makes it easier also. When we are going in and out the house we have him sit, if he is going out also he must sit to get his leash on. He is only 3 months old but it is working very well, hope this helps |
