Whippet chasing second dog — training tools that help

A one-year-old Whippet relentlessly chasing and nipping your other dog is a pretty classic combination of sighthound prey drive, adolescent energy, and zero reliable recall — and the hard truth is that the right tools can genuinely help, but only once you're also working the underlying behaviour. Good equipment amplifies good technique; it doesn't replace it. That said, the right gear does make a real difference for exactly this kind of challenge. To point you toward the right thing: what's the second dog — breed, size, temperament? And have you made any attempts at recall training so far, or is that still ground zero?

That tracks perfectly — once a Whippet's visual system locks onto movement, your voice becomes wallpaper. The Labrador being stressed is the urgent part; prolonged pestering like this can genuinely damage their relationship if it's not interrupted consistently. Before you can work recall around the other dog, you need a reliable recall signal in low-distraction settings first, and then a way to practise at distance without her being able to self-reward by completing the chase. Can she be off-lead anywhere safely at the moment, or is she always on lead outside the home?

Right, so the garden is both the training ground and the problem zone — which actually helps, because you have a controlled space to work in. Here's what I'd recommend as your single most useful piece of equipment right now: a 10-metre training line, specifically the Flexi Vario Training Lead or, even better, a simple flat-webbing long line like the Trixie Long Training Leash in 10m. Pair that with an Acme 211.5 dog whistle. The long line lets her move freely in the garden, feel like she has autonomy, but you have physical backup the instant she locks on to the Labrador — you can interrupt the chase before it completes, which is critical, because every completed chase rehearses the behaviour. The whistle gives you a recall cue that's completely distinct from your voice, carries further, and you can condition it to mean 'something brilliant is happening over here' before you ever use it around the other dog. Start whistle recall training when the Labrador is inside, get it bombproof with food rewards, then introduce it on the long line in the garden with both dogs present. The line is your safety net while the whistle becomes reliable. Would you like guidance on exactly how to condition the whistle recall from scratch?

Yes, managed separation is important right now — not permanently, but enough to stop the Labrador living in a constant state of anticipation and stress. Baby gates are useful here so they can see and smell each other without the Whippet being able to physically get to him. For the whistle conditioning: load it in three short sessions a day away from the Labrador entirely. Blow the whistle once — not repeatedly — then immediately deliver five or six small high-value treats in quick succession, right at your feet. Do that fifteen to twenty times a session for about a week. You're building a strong emotional association before you ever ask her to actually move toward you. Once she's spinning toward you the moment she hears it in low-distraction settings, put the long line on in the garden and practise there with the Labrador calm and at a distance. The line means a mistake can't happen — she physically cannot complete the chase. Over time, as the recall becomes faster and more consistent, you shorten how much line she has. The Acme 211.5 is the standard for this — it's what most gun dog trainers use, it's consistent, and it won't wear out. Get two so you always have a spare with the same pitch.

Nail those two things first — honestly. The long line and the whistle recall are the foundation everything else rests on. The one addition worth making early is a good treat pouch you can wear in the garden so rewards are instant and you're not fumbling in your pocket. The Dogtastic treat pouch is a decent, affordable option. But don't get distracted by gadgets. The temptation with a persistent chasing problem is to think there's a device that solves it — there isn't. What solves it is interrupting the chase reliably before it completes, conditioning a strong alternative behaviour, and giving the Whippet enough legitimate outlet for that drive separately, long walks, lure coursing if you can access it, or flirt pole sessions one-on-one. The Labrador will start to relax once he learns the chase doesn't always get to happen. Give it four to six weeks of consistent work and you should see a real shift.
