Oh another thing I thought of is during play time pay the most attention to your older dog, I did this with Roscoe and he felt like he was still the "baby" the first time he began to even want Sukie around was during playtime because he KNEW he was going to the most important. Now a few months later it is equal and they both know they are loved and dont fuss much unless I play hide and go seek and they can't find mommy LOL!!
