BLUETREE Dog Doorbells

The verdict

A seven-dollar strap of bells that solves a communication problem — when you hold up your end of it. The strap hangs over a door handle and carries seven 1.4-inch bells, and three snap positions set the length between 28.7 and 33.3 inches, so it can sit where a small puppy's nose reaches or where a tall dog's shoulder does. BLUETREE describes heavy-duty nylon webbing; the property that matters is simply that the bells are loud enough to hear from another room, because a signal you miss is not a signal. Baxter & Bella's trainers list it on their puppy-products page, and it is the default pick by a distance — 4.6 stars across 39,834 ratings, and Amazon's Choice in the category. The honest caveat is behavioural rather than mechanical. Teaching the bell means answering every ring for the first few weeks, and a fair number of dogs work out inside a week that ringing produces a trip outside whether or not they needed one. At this price a failed experiment costs less than a bag of treats.

Drawbacks

• Only works if every ring gets answered — and some dogs learn to ring for fun
• Hangs over a door handle, so a door with no handle needs another mounting
