Mr Black meets the big boys

It's been interesting to watch the behaviour of our 2 adult male Vizslas around the 3-week old puppies. The puppies were finally old enough to come out their whelping box. They were exploring the room this particular evening. Chili and Tyro (full brothers), lay just outside the room in the doorway, keeping a very respectful distance.

Then as one of the puppies, Mr. Black, approached them, they weren't sure what to make of him. They stood up, sniffed, but as he got closer, Chili (on the L) decided it wasn't safe to stick around and left. Tyro (R), on the other hand, was much more curious and interested. He decided to risk his safety and stay but he's still not certain what Mr Black is doing to do or where he's going to go. Tyro still wanted to maintain a safe distance but there was a lot of approach-avoidance behaviour going on.
