Dog Collars

Our adjustable dog collars come in four sizes, XS to L, in colourful Colour Drops prints, classic tweeds and waterproof designs. Each one has a sturdy D-ring for your lead, and most have matching accessories in the same design.

Dog collar sizes

Measure around the base of your dog's neck where the collar will sit, keeping two fingers of slack, then match that measurement to the chart. Each size adjusts across a wide range, so most dogs fit comfortably inside one size.

Not every design has every size in stock at once, so check the size options on each collar. Our dog collar size guide and how tight should a dog collar be explain measuring and fit in more detail.

Puppy collars

Puppies grow quickly, so measure your puppy's neck before you order rather than guessing a size, and check the fit regularly with the two-finger test. Every collar is fully adjustable, so you can let it out as your puppy grows and move up a size when you reach the end of the range. Our puppy collars guide covers first collars in more detail.

Collars for small dogs

Our XS and S collars are 1.5cm wide, the narrowest in the range. Measure your dog's neck and pick the size whose range it falls within. For a lighter matching lead, our Lightweight Mini leads are also 1.5cm wide. See our guide to the best dog collars for small dogs.

Colourful and patterned dog collars

If you want colour, our Colour Drops prints include Wanna-Bee (bees), Candy Floss, Spring Dreams and Olive it Hot, alongside pinks such as Blush Leopard and Flamingo Fling. For darker morning and evening walks, look for reflective light stitching, listed on each Trail & Glow collar's product page.

Tweed dog collars

For a classic look, choose from tweeds and plaids including Plum, Mayfair, Charcoal, Sage, Lavender, Oxford and Forest Tweed, Heritage Plaid and Mulberry Plaid. Our tweed collars don't have reflective stitching, so for darker walks a Trail & Glow collar is the better pick. Shop all tweed dog collars or read our tweed dog collars guide.

Waterproof dog collars

Our Waterproof Adjustable Collars come in Jet Black, Forest Green and Mulberry, in the same XS to L sizes. They match our waterproof leads and are also sold together as a waterproof lead and collar set. Browse waterproof dog collars or read our waterproof dog collars guide.

Matching collar, lead and harness sets

Most of our collars have matching accessories in the same fabric, such as a dog lead, dog harness, dog bow tie or poo bag holder. To buy the look in one go, browse our matching harness, lead and collar sets, or read why a dog collar and lead set makes sense.

Dog collar questions

What size collar does my dog need? Measure around the base of your dog's neck, keep two fingers of slack, and choose the size whose range includes that measurement.

How tight should a dog collar be? You should be able to slide two fingers flat between the collar and your dog's neck.

Are your dog collars reflective? Our Trail & Glow collars with reflective light stitching say so on their product page. Our tweed collars are not reflective.

Can I attach an ID tag? A collar is the usual place for your dog's ID tag. Browse our dog ID tags.

Collar or harness? You can use both: a collar to carry an ID tag and a harness for the lead. Our collar versus harness guide explains the differences.

Please note: all dog accessories are subject to wear and tear, so check your dog's collar regularly to make sure it's still safe to wear.
