16 weeks ...No Fear exhibited in relation to people, places or things

As Puppy Madonna approaches the "end" to the sensitive period... she still exhibits an open curiosity to enviornmental sitimulus. She also shows no reservations interms of contact with new persons ( strangers).

She exhibits a wide range of play behaviors with other dogs very much conditioned by their size, degree of aggressiveness and age.

Also, there seems to be a coorelation with the loss of some of her baby teeth and a very noticible increase in retrieve "drive".  Her object oriented play has definitely taken a definitively new direction. She is much more intrestested in chasing objects, and retreiving them. This was also stimulated i belive by some "clicker training" conditioning.  But that seems insufficient to explain the large "quantitative and qualitative" increase in these behaviors.

Her "prey" kill/shake behaviors seem about the same level of intensity. She will continue to growl and kill/shake toys aggressively.  No big change there but the retrieve is definetly up.
