My dogs regularly run into the screen door. To be fair though, I’ve done it too.
My other dog with a broken ankle jumped out of her pen and pooped all over the living room. It’s smart of her to figure out how to escape, really, but also dumb because she has a broken ankle and though she’s in a cast, jumping about won’t help her heal.
When I was a baby, my dad had a dog that he had owned since he was a teen. The dog died when I was two or three so I don’t remember him all that much, but he was not the brightest so I have been told a bunch of funny stories.
He ate everything. He ate moondough, crayons, a chew-proof iron hose, pool noodles, bees, shoes, toys, and once even swallowed a rawhide knot (which we do NOT use anymore and I would strongly advise against feeding to any animals) and it was stuck in his stomach for a while until he threw it up. He also had a tumor on his foot that he chewed endlessly (We got it removed but he was so old that he wasn’t alive very long after that). He was a golden retriever and lived to be thirteen or fourteen, so he lived a pretty full life, and we loved him. But he was indeed quite stupid.
