Blue Dog Chain Diamond Cuba Link dog collar chain (18-inch)
Product description
What it is and the kind of job it does
This Blue Dog Chain “Diamond Cuba Link” collar is a metal dog chain style necklace/collar, aimed at the visual side of pet accessories: a blingy, Cuban-link look that catches the eye more than it focuses on everyday “comfort-first” features. It’s built for small, medium and large pets (including cats, puppies and other small animals mentioned in the description), so you’re essentially looking at a statement piece for walking, training sessions, travel, or parties and celebrations.
On paper, it’s the sort of accessory you pick when you want your pet to look distinctive—something that reads “jewellery” rather than “standard collar”. If you’re mainly after basic leash control and daily wear with minimal fuss, this may not be the best match. But if aesthetics and that polished, diamond-set effect matter to you, it can do a lot for the overall look.
Key features that matter in real life
The most noticeable elements, based on the product information, are the link design and the way it’s finished. The chain is described as finely polished metal and “set with diamonds”, with an elegant colour look. There’s also a side-opening box buckle described, which is designed to make putting it on and taking it off easier, and to support safe fitting.
In terms of durability, the description claims it is wear resistant and “not ease to rust”. That’s a useful point for something metallic you might take on walks in different conditions.

You also get a key limitation straight away: it’s not adjustable. That affects what you can realistically do with fit—once you choose the length, that’s the length.
Dónde destaca (and where it might disappoint)
Where it stands out is the statement finish. The design is clearly intended to look attractive and “enhance your pet’s charm”, and it’s light enough, according to the description, to avoid being a burden on your pet’s neck or interfering with movement.
That said, “lightweight” is a broad promise. Since the chain is metal and the collar is not adjustable, it’s worth being careful with sizing and comfort expectations. If you’re hoping for something that feels like a soft fabric collar or sits comfortably for long periods without any urge to check how it’s sitting, you may find it a bit less forgiving than everyday collars.


There’s also a practical consideration: you’ll need to measure properly and choose the right length first. If you’re buying without measuring, you risk ending up with something that’s too tight or doesn’t sit right.
Size and fit: the part you shouldn’t skip

This model is sold with an 18-inch length option, and the chain width is listed as 15mm (for this item type). The listing also says the collar chain is not adjustable, so sizing is on you.
The description recommends measuring your pet’s neck circumference using a soft tool and choosing the correct size. If you want an “oversize effect”, it suggests adding 1–2 inch to the original measurement.
A quick example
Imagine you measure your pet’s neck circumference and it comes out to a number that would sit just under the 18-inch length option. If you want the links to hang a bit more loosely for a softer look (and you’re comfortable with that fit), you’d follow the guide and add 1–2 inch before choosing.
Colour options and what to consider
The description lists colour variants: gold, blue, pink and silver. Which one you choose is mainly about how it’ll match your pet’s coat and the look you’re going for.

Just don’t overlook the fact that a metal chain can visually dominate the outfit—so if you want something subtle, a diamond-set Cuban link style may not be the direction you want. But if you’re buying specifically for photos, parties, or an extra “bling” day, these colours can make the accessory feel more like jewellery than a plain collar.
Usage tips for walking, training and parties


The listing suggests several scenarios: training, walking, travelling and jogging, plus wearing for party and celebration occasions.
A practical way to think about it: use it when you’re happy with the statement look and you’re supervising your pet (especially early on, until you know how it sits). For training and short walks, it can work well if the fit is correct and your pet isn’t constantly rubbing it on things.
For parties or photos, it’s probably at its best—this is the kind of accessory that turns a normal day into something a bit more “event-ready”.
What to check before you buy

Before committing to this 18-inch Blue Dog Chain, here are the checks that matter most:
- Fit: it’s not adjustable, so measure neck circumference with care.
- Comfort: metal chain jewellery can look great but still needs correct sizing to avoid rubbing.
- Length choice: if you want a looser “oversize effect”, the description recommends adding 1–2 inch to your measured circumference.
- Pet type: the description claims suitability for cats, puppies and other small pets as well as dogs, but you’ll still want to confirm the fit works for your specific pet’s neck and behaviour.

Final verdict
Should you buy it?



It’s a solid pick if you want a diamond-set Cuban link metal collar/necklace look and you’re confident you can measure for a non-adjustable 18-inch fit. This is also the sort of accessory that makes sense if you’re dressing pets up for walks, travel, training days with a style focus, or parties.
You may want to skip it if you’re after an adjustable, everyday, comfort-first collar. Also, if you’re not comfortable measuring and choosing the right length, the non-adjustable design can be a deal-breaker.
