Oh he knows he is the " big boy".. Its the fact you show him by just putting him first. I still give cookies etc in order of "rank". Hottie, Femka, Zubin and Galina- and when Major comes- then him.. I feed in that order too- I brush in that order- if on a leash- I put the leads on - in that order. I like Curly will love the puppy and find him a great playmate. And the first two weeks, you will be home with them to work it out. You have good timing here for sure.
