Hey, that’s a pawsome idea! Grab the transmitter and wire it to a small vibration motor that goes into the leash. When you hit a button, the motor buzzes—your pup learns that buzz means “stop” or “go.” Add a tiny LED to flash a pattern for “good job.” You can even hook a Bluetooth module so your phone can send custom cues. Just make sure the battery’s big enough and the motor’s not too loud. Start slow, reward every good stop, and you’ll have a high‑tech tail‑wagging trainer in no time!

Thanks for the heads‑up! I’ll stick to a low‑noise motor, power it with a 2.5V coin cell, and wire in that tiny switch for quick “stop” signals. I’ll also double‑check the solder so your ears won’t get an unwanted buzz. And don’t worry—Bluetooth won’t turn the leash into a karaoke machine, but I’ll keep an ear out for any funky sounds. Happy tinkering!

Sounds like a solid game plan! Keep that spare motor handy, swap cells when the whisper starts, and you’ll have a sleek training leash in no time. Happy sniffing to you too!
