Try this one: https://x.com/buitengebieden/status/1818204396041154600 I promise it's cute. This is not a trick.
I had a sheltie when the kids were little. Back then, I could send them out by themselves to play in the creek or whatever. If I could not hear them, I would send the dog out to 'find the babies'. Being a sheltie, she would not stop barking when she was with them. Instant pre technology locator.
