“Ability to distinguish what IS a chew toy from what ISN’T”.
I got a kick out of the brain diagram as well. Although with the two dogs we’ve owned I’ve been amazed at how they can tell the difference between one of their toys and the kid’s toys (stuffed animals, etc.) and of course shoes and socks.
Although the first dog did chew up a toy tiger/figure type thing. My young daughter was crushed! Turns out the thing was made out of hide (cow?), and the hair colored like a tiger. That dog was also apt to eat any of their sandwiches that they left down low on the coffee table, etc.
Our current dog doesn’t get into much - even food left low. I’m not sure if that is smart - or it is just well-behaved. Smart would be “I’m going to eat this yummy sandwich if they are too stupid to leave it out for me!”
Our wolfhound used to reach DOWN to take the roast off the kitchen counter.
When my son was about six years old I gave him a roll for a snack. It was the last roll. He was standing in the Family Room smiling at me in gratitude when our dog, now sadly departed, walked by, and without slowing down or changing stride turned her head and cleanly snatched that roll right out of my son's hand. Not to be mean but the look on my son's face was priceless and I couldn't stop laughing.
