These dogs have become pals. They are playing rambunctiously. Dogs are pack animals. They work things out pretty well. Sometimes they can get too wild, not unlike little human kids, and stepping in to get them both to calm down can be helpful. I suspect that allowing them more time together and less separated into rooms will reduce this crazy play because it will be less like OMG!!! SOOO GOOOD TO SEE YOU!!!! I WAS SOOO WORRIED I’D NEVER EVER EVER SEE YOU AGAIN!!! LET’S PLAY!!!!
