On the daily check
Ancol's own instruction is to check the fit of the collar every day for comfort and security, which is not a one-off job the way a fixed collar can be. If that is not a routine you are confident you will keep up, a well-chosen fixed collar may suit you better than an adjustable one.
Why we chose it
Two sizes covering 30-70cm means one collar can often see a growing dog through several stages rather than needing replacing each time. The swimming-suitable nylon is the other reason - a lot of 'weatherproof' collars quietly mean 'don't get it too wet', and this one doesn't.
— Matt, founder
Size guide & how to measure
Collars are sized by the neck girth — the measurement around the base of the neck where the collar will sit.
How to measure
- Wrap a soft tape around the base of the neck.
- Add room for two fingers between the tape and the neck.
- Use that measurement to pick a size whose range it falls within.
| Size | Typical neck girth | Rough guide |
|---|---|---|
| XS | 20–28 cm | Toy breeds, kittens |
| S | 26–36 cm | Small dogs |
| M | 34–48 cm | Medium dogs |
| L | 46–60 cm | Large dogs |
| XL | 58–72 cm | Giant breeds |
Ranges are approximate and vary by style. Always check this product’s Specifications for its exact measurements.

Full description
Most collars get put on once and left alone until they visibly need replacing. Ancol's own instruction on this one is to check the fit every single day, which is a different habit to build - not because the collar itself changes, but because a growing or seasonal-coat dog can outgrow or shrink out of a setting without anyone noticing gradually.
This is Ancol's Reflective Bone Adjustable collar: a reflective design on a hardwearing nylon base, suitable for all weathers and swimming, with snap-buckle fastening. It's available across three sizes in total - small (20-30cm), medium (30-50cm) and large (45-70cm) - and this page covers the medium and large.

On the daily check. Ancol's own instruction is to check the fit of the collar every day for comfort and security, which is not a one-off job the way a fixed collar can be. If that is not a routine you are confident you will keep up, a well-chosen fixed collar may suit you better than an adjustable one.
Who it's for: owners who want one collar that adjusts across a size range rather than buying again as a puppy grows, and who walk in conditions - rain, mud, water - where reflective, weatherproof material earns its keep.
