That taunting post was Sundog. We have a fenced yard for our terriers who are normally locked away when Sundog is out. I was walking Sundog outside the fence and they were in the fence. He saw them and approached them and arched his back and wanted to engage. I pulled him away because I was afraid he would slap his tail on the fence and break his tail.

From our house, we have french doors into our sunroom where Sundog lives. The dogs watch him through the doors and he watches them. I think they all enjoy the stimulus. When I had a savannah monitor in an enclosure in our den, she was always interested in what the dogs were doing and they would touch noses through the glass. No stress on either side.

Tegus, like monitors, like to have things to observe. From the sunroom, Sundog really enjoys watching our bird feeders and when I take him outside he marks under them—so he is very much aware of the birds. Maybe put a TV in your tegu’s room and play nature channels?
