Yesterday evening Hobo was out & about on the driveway so I decided to see his & Chip's reactions to seeing another male.
It was so interesting to see that it only takes one look, a male knows he's looking at another male in a split second.
Their reactions to seeing a female is so different from this, the body language is completely different.

When Hobo & Chip saw each other they both stood up as tall as they could & tried to look as big as they could. Lots of posturing, staring, & really trying to intimidate one another.

I let them look for probably less than 1 minute. That's enough, Chip doesn't need the stress. I just think that seeing the different ways they behave is really interesting.
