Which one?

During the last days Caspar got to know some new tastes for him. 
Little healthy treats (but not suitable for the trouser pockets)
This morning I was curious which would be his favourite snack.
His choice was: Banana, carrot, apple, blueberry  ;-D

Later we visited a busy town and even watched a train at the station.
He also got a new harness.
There is so much to learn for a wee puppy :-D
