So sad that they had to let this worthless piece of s*** Neil deGrasse Tyson on that guy's channel to take away from how smart his dog is

This is super interesting because it's a very good way to prove if dogs having theory of mind, if it can make an inference on who you think is Einstein when you add 2 more one that is closer to Einstein in the fact that he is more human shaped then that can be pretty solid proof. Test it by putting two toys the one more Einstein like but very different in look only being human in shape further away and the one less darwin like closer if she looks at all the toys and infers who you think is darwin after training her on Darwin it will be pretty solid proof if it confuses her it wouldn't disprove theory of mind

I believe all dogs have this ability. The commutation between that man & dog is the best Ive ever seen. That relationship of Love is the difference.

Chaser is the kind of dog where if you make eye contact and keep staring, you start to feel like you're being rude.

dogs are very sentient. Most of the time they’re better companions than humans too.

Chaser died a year after Dr Philley on July 23, 2019. I think she deserves to be posthumously inducted into #MensaInternational.

If I believe in any kind of after life, which is doubtful now in my truly old age, I hope it would mean meeting up with the essences, souls for lack of a better more accurate word, of all the companion animals I have shared my life with in my past. I don't "expect" any humans to "welcome" me. The few good ones would be too busy working on their own continued growth of their "souls" and being busy being human again or whatever. But the animals I have known are better more advanced creatures than any human. They might have a welcoming moment for me, maybe. But choosing to "go into the light" is not desirable. Had enough of re-incarnating, thank you! But the animals, it might be worth something to "feel" them again. Oh well…

The names are written on the toys. Cheating.
