Chaos Theory Crystal Dog Collar
From £70.00
- Your Design: Choose from 28 leather colours and pick your own Swarovski® crystal colours.
- Made to Measure: Handcrafted to fit your dog perfectly, from tiny 7.5″ necks all the way up to 26″.
- Built to Last: Fitted with strong stainless steel hardware that is highly rust-resistant for everyday wear.
How to measure your dog's neck
- Wrap a soft tape measure around the middle of your dog's neck, held fairly snug against the fur.
- Note the measurement in inches — this is your dog's neck measurement.
- Choose the size where that measurement falls within the range, ideally towards the smaller end to allow for adjustment.
Example:
If your dog's neck measures 10", choose the 9" to 11" size. This means the collar adjusts between 9 and 11 inches — it does not mean the total length of the collar is 11".
If measuring from an existing collar, measure from the end of the leather to the hole you use — not the total length of the collar. The total length will result in a collar that's too big.
If you're unsure which size is right for your dog, please get in touch — we're happy to help.
- Handmade to order
- Dispatched within 3-7 working days

The Chaos Theory dog collar is one of our most popular Swarovski collar designs, and it’s easy to see why. With a completely random, asymmetric pattern of crystals in the colours of your choice, on any of our 28 Italian leathers, there are thousands of possible combinations, and the end result is a stunning collar that is as unique as the dog wearing it.
To create your very own Chaos Theory collar, you’ll have the choice of either Crystal or Crystal AB as the large sized crystal. Then you can choose up to three medium sized Swarovski crystals from a choice of ten possible shades.
Once you’ve chosen, we’ll get to work. Your collar will be crafted by hand in our Northumberland workshop from Italian leather hides, with each and every Swarovski crystal secured in place with care so that they stay exactly where they’re supposed to, on the collar. We’ll add a soft calf leather lining so that it sits smooth and comfortable against your dog’s neck, and finish with solid stainless steel hardware that will stand up to every walk, whatever the weather.
Why stop there? Complete the look with our Swarovski Crystal dog lead in matching colours.
Perfect for breeds such as: Maltipoo, Boston Terrier, Bulldog, Havanese, Scottish Terrier, Tibetan Terrier

FAQs
How long will my order take?
All collars and leads are made to order. We typically dispatch within 3–7 working days, with Royal Mail Tracked 48 adding 2–3 further working days in the UK. Most orders arrive within 5–10 working days. A dispatch notification is sent by email. If you need a collar by a specific date, contact us before ordering.
Can I exchange my collar if it doesn't fit?
Yes. If the collar doesn't fit when it arrives, you can exchange it for a different size. The most common reason for a poor fit is measuring the total length of an existing collar rather than the dog's neck directly. Full details are on our returns and exchanges page at petiquettecollars.co.uk/returns.
What’s the difference between Crystal and Crystal AB?
Crystal is a clear, bright stone that catches the light cleanly and works beautifully against any leather colour. Crystal AB has a special iridescent coating that shifts colour depending on the angle and the light around it, picking up whatever shade is nearby. Both are stunning, and both are available as the large stone on your collar. If you’re torn, drop us a message and we’ll help you choose based on your leather colour.
Are the crystals secure enough for everyday wear?
Every Swarovski crystal is individually secured by hand in our Northumberland workshop. We’ve had customers wearing the same Chaos Theory collar for years of daily walks without losing a stone. If you do ever lose one, get in touch and we’ll do our best to help.
What leather colours can my collar be made in?
Your leather collar can be made in 28 Italian leather colours: Acorn, Baby Blue, Baby Pink, Black, Bottle Green, Candyfloss, Chianti, Daffodil, Dove, Dusky Pink, Easter Rose, Jaffa, Lime, Madeira Blue, Mushroom, Olive, Peanut Butter, Purple Velvet, Royal Purple, Ruby, School Grey, Shamrock, Signal Blue, Spearmint, Teal, Thistle, White, and Willow.
