They are doing very well.. Chloe LOVES instigating him.. she will chew her toys very close to his face trying to entice him to chase after her.
Sometimes Leroy gets a little rough and we have to separate them or Chloe gets irritated with him, but he doesn't mean to he's just a big clumsy puppy.
Once he learns some more manors I'd say things will be perfect around here, but for the most part i think Chloe enjoys having a brother to play with!
