This is a specific conversation about Dog training — equipment and tools that help — ask about yours and get one honest answer for your exact situation.

A Boxer with a diagnosed heart murmur changes the training picture considerably — you want to build calm, focused behaviour without pushing the heart rate up, which rules out a lot of the high-energy recall and agility work Boxers typically thrive on. Good training tools amplify good technique rather than replace it, but the right equipment genuinely does make a difference for specific challenges like this. To point you in the right direction: what are you trying to train for right now, and what have you already tried with him?
He's called Bruno — four-year-old Boxer, grade two murmur picked up at his last check. The vet said light exercise is fine but nothing that gets him really ramped up. I'm mainly trying to work on loose-lead walking and staying calm when guests arrive. He gets very bouncy and excited and I'm worried about getting him too wound up during training sessions.

That's a very sensible focus — loose-lead and door manners are exactly the kind of low-arousal, stationary work that suits Bruno's situation well. Short, frequent sessions with clear markers and immediate rewards are your friend here. The key is keeping his brain engaged without his body going into overdrive. Have you been using a clicker or any kind of marker word, or has it mostly been lure-based so far?
Mostly luring with treats held in my hand, which he follows okay but then he loses interest or jumps up trying to get to them. No clicker yet.

That jumping-to-get-the-treat pattern is actually making the arousal problem worse — he's anticipating the food and spiking before he's even done anything. A clicker changes the dynamic entirely. The click marks the exact calm moment you want, and the reward follows a beat later, which means he learns to stay still and think rather than lunge. For Bruno specifically, I'd recommend the Clix Multi-Clicker by Company of Animals. It has an adjustable volume dial, which matters for Boxers — they can be sound-sensitive and a full-volume click indoors can startle them into that bouncy overreaction you're trying to avoid. Pair it with a treat pouch worn on your hip so rewards come from a consistent, calm place rather than your hand waving in front of his face. The Clix clicker is widely available on Amazon UK and costs around £5-6.
I didn't know you could get a quieter clicker — that makes a lot of sense for him. How short should the sessions be given his heart condition?

Your vet is the final word on that, but for low-arousal clicker work with a dog in Bruno's situation, three to five minutes is a solid ceiling — stop before he gets excited, not after. You're looking for calm attentiveness, so end on a successful quiet moment rather than pushing for one more rep. Two or three of those short sessions across the day will do far more than a single fifteen-minute slog that ends with him bouncing off the walls. The clicker work is genuinely gentle on the body — it's almost entirely mental effort — but watch his breathing and if he starts panting heavily or getting really wound up, that's your cue to stop and let him settle.
That's really helpful. I'll grab the Clix clicker and give those short sessions a go. Thanks.

You're in good shape — the combination of a low-volume marker, short sessions, and working on exactly the right behaviours for his lifestyle means Bruno can make real progress without any cardiovascular stress. Keep your vet in the loop as you go, and if the murmur grade changes, revisit whether even this level of mental engagement needs adjusting. Good luck with him — Boxers are brilliant when they're calm enough to think.
