Mikivery Martingale dog collar (nylon adjustable, purple) for medium and large dogs
Product description
What it is and why people buy it
A martingale collar is a fairly specific tool: it’s designed to offer gentler, more controlled training pressure when your dog pulls or moves in a way that would otherwise make you lose handling. The Mikivery Martingale Dog Collars uses soft nylon webbing, adjustable sizing, and heavy-duty nickel plated steel hardware to help with everyday comfort while still doing the job when you’re training.
On paper, it’s aimed at medium and large dogs, with collar widths listed as 25mm and two size ranges (M and L). If you’re looking for a standard flat collar for walks, this might feel a bit “training-focused”. If you’re working on pull/response issues and want something that tightens when pulled (without going for a buckle-based design), it’s easier to see the appeal.
The essentials

The collar uses adjustable sizing so you can match it to your dog’s neck measurements. It’s made with soft and breathable nylon webbing, described as helping keep the neck snug and dry. The colour is produced via a dyeing process intended to stay more vibrant and not fade as easily.
There’s also a clear hardware choice: the martingale accessories are made of heavy duty nickel plated steel with a smooth, shiny finish. That matters if you’re buying for regular use, because cheap-looking fittings can become an annoyance fast.
A key point in the design is the “no buckle” concept mentioned in the description, with the martingale tightening when pulled. That’s the whole idea of a martingale: it adds a layer of control during training rather than relying purely on how tight you set it and leaving it at that.
What stands out in use



Where this collar is likely to feel most practical is in training moments—think of the “half-pull” situations where you need consistent handling without constant fiddling. For example, during a short session in your local park, you can keep the collar in place, and when your dog leans forward, the martingale action helps reduce the chance of them slipping out compared with some looser styles.
It’s also positioned as being for medium and large dogs, so the proportions are meant to suit those sizes rather than trying to cover everything.
Things to keep in mind before buying
Martingale collars aren’t for everyone, and the safety instructions included here are pretty important. This collar is stated as NOT for tie out, and you should never leave your dog unattended with a collar on. Also, you’re advised to make sure there’s enough room to fit two fingers under the collar when using it.

One more limitation to be aware of: because it’s built for training and tightening when pulled, it may feel more “active” than you want if your priority is a purely comfy, relaxed accessory for casual wear. In other words, if you mainly want a simple everyday collar for calm dogs, this could be overkill.
Who it suits (and who should skip it)
It’s a sensible pick if you want a martingale-style training collar with adjustable sizing, soft nylon comfort, and sturdy metal hardware, particularly for medium to large dogs.
You may want to skip it if you’re looking for a tie-out solution (this one isn’t for that), if you don’t plan to train at all, or if you’re not comfortable checking fit and following the guidance about two fingers under the collar.



It may not suit you either if your dog is very sensitive to any tightening action—martingale collars can work brilliantly for many dogs, but the “tightens when pulled” part is exactly what some owners don’t want.

Is it worth it?

Worth buying if you’re specifically after a martingale training collar for a medium or large dog, and you’ll set the fit correctly (two fingers under the collar) while using it for supervised training. The nylon build and nickel plated steel hardware are the kind of choices that usually make sense for everyday wear, assuming your dog is being handled responsibly.
It’s not the best choice if you need something for tie out or if you only want a basic non-training collar for relaxed walks. In that scenario, you’ll probably find simpler designs fit the bill better.
Mini FAQ
How do I choose between the M and L size?



Choose based on your dog’s neck size within the ranges given for M (35.5cm-53cm) or L (43cm-63cm). The description suggests the size chart can help, so it’s worth using it rather than guessing.
Is this collar safe for tie out?
No. The listing explicitly says it is NOT for tie out.
Will it hurt my dog if it tightens?
It’s designed to tighten when pulled as part of training control. That said, the listing also advises fitting so there’s room for two fingers under the collar and never leaving your dog unattended with a collar on—so proper supervision and correct fit matter.
Does it use a buckle?
The description mentions a “no buckle design”, so it’s not the typical buckle collar style.
Does the colour fade easily?
The dyeing process is described as making the colour more resistant to fading, but the exact durability isn’t quantified in the information provided—so expect it to hold up reasonably well over regular use rather than treating it as indestructible.
