Greyhound puppy training tools for multi-pet homes

A 10-week-old Greyhound in a home with a smaller dog — that's a brilliant but genuinely tricky setup from the start, because the size gap between them is only going to grow fast. The first few months set the patterns for life, and with a sighthound puppy especially, the right tools matter enormously — the wrong collar or lead now can create pulling habits or even escape risks that are very hard to undo later. To point you in the right direction: how old is your smaller dog, what breed is it, and what's the main thing you're trying to work on with the Greyhound pup right now — is it basic recall, lead manners, or something around how the two dogs interact?

That's exactly the right instinct — a 10-week Greyhound is already deceptively powerful, and by 6 months she'll be a different animal on the lead entirely. The key issue with sighthounds and lead training is that standard flat collars are genuinely unsafe for them — their necks are wider than their heads, so they can back out of a flat collar easily, which is dangerous near traffic or when she gets startled. Before I give you a specific recommendation, one quick question: are you planning to walk them on separate leads at the same time, or are you looking at a way to manage both dogs together on one walk without them tangling?

Perfect — separate leads is the right call, especially at this age. Here's my clear recommendation for the Greyhound: get a Ruffwear Flat Out Collar in the extra-small size for now, paired with a standard 1.2m training lead. The Flat Out is a martingale-style collar, which means it tightens slightly under pressure rather than staying loose — this is the standard choice for sighthounds precisely because it prevents the backing-out escape that flat collars allow. It's adjustable, durable, and sized appropriately so it won't dwarf her at 10 weeks while still giving you real control. The narrower profile also means it won't intimidate or confuse her the way a head halter would at this age. Start every walk with her on her own so she learns the lead is about her behaviour, not about following the Chihuahua — that separation in the early weeks will pay off significantly once she has size and speed.

Yes, exactly that — you size up as she grows, and the martingale principle stays the same throughout her life. Most adult Greyhounds end up in a medium or large martingale, so you'll probably go through two sizes before she's fully grown at around 18 months. The Ruffwear range scales up consistently, so the transition is straightforward. One thing worth knowing: Greyhounds have very lean necks with not much padding, so padding on the collar matters more than with other breeds — the Flat Out has enough webbing width to be comfortable without being bulky. Keep the Chihuahua's existing collar and lead completely separate and don't let the pup treat the smaller dog as a pace-setter on walks yet — she needs to learn lead pressure means slow down, not speed up to catch her housemate.

Great choice — you're starting exactly as you mean to go on, which is the only way with a sighthound. Consistent, calm lead sessions now, even just 5 minutes at a time at 10 weeks, will make a huge difference by the time she's got the speed to really test you. Good luck with both of them — a Greyhound and a Chihuahua is quite the combination.
