2. We had a small mutt that was WILD about tennis balls
Fri Jan 9, 2026, 09:33 AM
Yesterday

I set a mirror on the floor leaning against the wall, and sat down facing the mirror with the dog in front of me, also facing the mirror. Suddenly I pulled a tennis ball out from behind me, so the dog could see it in the mirror. The dog IMMEDIATELY turned around to grab the tennis ball! The dog thoroughly understood that it was seeing a reflection.
The odd part is, after I stood up, the dog set the tennis ball down in front of the mirror, then took a quick look BEHIND the mirror. Was he just checking, to be sure there wasn't really another ball back there? Or was he thinking "How DOES that thing work?"
