I have been trying to find out (breed specifically) when cavaliers test the waters and what the different stages entail as they mature.

At 3 months Bella's hyper personality was in fully swing, and at 5 months it is still going strong, and she seems to have stopped listening to us (except when we have yummy treats).

Does it get more challenging as they get closer to a year old or will she start to mature (settle down)?
