Can button learners really learn all those words?

In this week’s Can Button Learners do X? We’re going back to the beginning. Lots of learners like Parker have pretty big boards, but this took a long time to build up! So this week we’re looking at where it all started for some of our prolific button users. This is part 1 of 2 cause I have so many good ones!

Do they ever use the buttons with other, or even across species? That would be awesome!

I posted another series of videos of them using them with other animals including across species!
