First day at primary school

Caspar had his first day at the "dog training school" for young dogs. He is a bit young, his classmates are mostly older. But he is now too old and too big for the puppy lessons.
Caspar was of course very excited, all those new senses/impressions. But he was also very attentive, learning new tricks fast.
Towards the end of the training hour the dogs were allowed to play with each other. The others running towards him was new for Caspar (he only knew it from single playmates), so he was at first a bit overwhelmed. But that lasted only a minute or so, and then he ran with the pack.
