Thanks so much for letting us know. I’m really sorry to hear he got spooked — that sudden clink of the connector can be surprising for some dogs, especially if their teeth catch it unexpectedly.
A few dogs do bounce back with a gentle re‑introduction, so if you’d like to try again, you could start by placing the toy on the floor, letting him sniff it at his own pace, and rewarding any calm curiosity. Sometimes removing movement entirely for a session or two helps rebuild confidence.
If he’s still worried, no problem at all — we completely understand. I’ve sent over our returns instructions and returns policy, so you can pop it back to us whenever is easiest.
