Super cute

  • Familiarity: I've put it through the wringer

Bought this collar for my little Chihuahua-Terrier mix and she loved it! the color is much brighter than in the picture and really stands out with my dogs white fur. She loves it! my dogs hair tends to go into the little loop for the collar and makes her scratch her neck like crazy after a long day of wearing her collar. It doesn't bother her really but I'm guessing its the same feeling of having your hair in a ponytail for too long.

Collar Up!

I have green and purple dusk for my two dogs. They are hardly ever actually on a leash, but when they are, these are so nice where you clip the leash to it. Tags can hang without making lots of noise with the little rubber tab. Light, and super cool. Always a fan of climbing rope , having some around my dogs just plain looks cool :)

It's knot just a fashion statement!

  • Familiarity: I've put it through the wringer

Seriously love this collar! So the fact that it is made out of rope its awesome because my boyfriend and I are both climbers but the rope is also super durable unless your pup decides to eat it. The Purple dusk is adorable on little miss Yuki and the sleek and simple design makes your neighbors dog wish they had one too. The knots can pull down occasionally when there is excessive tugging but it's really not that hard to adjust them back to normal after. However with rough play this bad boy will stay on and not come off. I really do like this collar for the look and functionality and I would recommend it if you are in the market for a good looking awesome collar.

Slim and good looking

  • Familiarity: I've used it several times

My dog now wears a necklace not a collar, it looks that good. It has a rubber spacer to keep the dog tags from jingling. There is no buckle that can break, which is why I replaced my 5 year old Chaco collar with it.

We Like It

  • Familiarity: I've put it through the wringer

My dog Cajun has the magenta one, which happens to be our favorite color. She is rarely on a leash, so this collar is mostly for attracting compliments (works great) and holding her name tag. I don't love it for leash walking, because I feel the small cord is kind of chokey (as opposed to a flat webbing collar), but since we rarely do that, this is our most favorite collar.

Zappa loves it.

Looks good. Works well. Metal eyelet on the back makes Leashing a breeze. I haven't had the slipping issues as mentioned in other reviews.(I have a 55 lb Black Lab Whippet Mix, who pulls constantly on leash[Working on it}) The knots are made to slip so its easy to use but the 180 turn they do through the front metal piece creates quite a bit of tension between the inner bends of the rope and the eyelets. Making it pretty hard get those knots to move just by pulling on collar.

A tip for less slip: After Sizing your dog to snug but comfortable size use both of your thumbs to push the loops of rope onto the face of the front piece. Then a slight adjustment of the knot postions to compensate for any slack created by this. The key to no slipping is the slight tension from the knot to metal eyelets.

As for Noise, their rubber tag does help but doesn't solve the problem of the tag hitting the metal front piece to which to mount. 2 possible solutions for future models for Ruffwear: Rubberize the front piece, increasing the grip on the ropes and reducing noise from tags. or put a rubberized logo on the piece, this deaden the initial sound and dampen any ringing.

Easy Homemade Solution: electrical tape, heat wrap, Vinyl Stickers or good ol duct tape. If done right this doesn't have to look trashy, will not make it silent but take the metallic clamor out of the jingling.

Advanced DIY Master Solution: remove rope from collar to free the front metal piece. Scuff with steel wool, prime and then use Spray - on Rubberized undercoating or bed liner. I would mask the eyelets for the rope, as the ropes movement will likely wear the rubber quickly anyway.
Is there room for improvment? Yes.
That said, this is still one of the better designs for a Dog collar I've found to date.

Well done collar

  • Familiarity: I've put it through the wringer

Love this collar. Runs bigger than you would think. I ordered a medium for my chocolate lab and I could use a small. But I love the way it looks and Ruffwear makes great products for dogs.

Great collar!

  • Familiarity: I've put it through the wringer

I bought this collar for my Great Dane, and I love it. It looks nice with the knots and has nice details, such as the tag silencer. The jingling noise doesn't bother me, but I thought it was nice of Ruffwear to take that into consideration. My dog is 160 pounds and doesn't pull much, but when he does, he pulls hard, and I haven't had any problems with this collar coming loose, unlike other reviewers. It's a great collar - it's simple and comfortable for my dog, and it looks nice :)

Loosens and is loud!

OK....this is round 2 with Ruffwear collars. I keep giving them a chance because I love the style, but unfortunately the quality is lacking. I tried the regular Knot-a-Collar first but was disappointed when a skinny little collar with a tiny buckle came for my 75lb lab. Not only was it flimsy, but it was SO LOUD because her tag would hit against the ring for her leash. Ding, Ding, Ding was all we heard, so we would take it off of her just to get rid of the, why have a collar then?? I saw this one and decided to give it a chance because the tag attaches differently which supposedly cuts down on sound. Not so! Its just as loud and no matter how often we tighten it on her, it loosens itself constantly so she can slip out of it. I'm still giving this 3 stars because I love the style and I will keep trying Ruffwear collars until I find the right one!

So far so good...

Got our stuff from Backcountry in the mail today and this was one of the items. As far as fit goes, the measurement held true for Maggie... After a field test in wet and dry environments, it held up well. We did notice (as others have in past reviews) that the knots tend to slip a little but I'll attribute that to it getting wet. Overall it does the job well and the fact that it's made of Prusik cord with barrel knots makes it kinda fun.

So far so good...

Low profile

My girlfriend loves this collar because it's nearly invisible on our huskies. It's quite thin, so it sinks into their fur instead of laying on top. However, since it's thin and has less surface area, I think it digs into their necks a little more when they pull on a leash. What I'm trying to say here is that I agree with another reviewer who said that this collar works best as a low profile"tag holder", but isn't ideal for lots of leash walking unless your dog is a non-puller (do those exist?). We don't use leashes that much, so it works well for us.

I purchased this collar in Aug. 2012 for my Lab Mix. (five months) Sadie and I walk every day to retrieve the paper and mail. She typically is not a puller on her leash and only weighs 40 lbs. However, I noticed that the hardware used to attach the leash is cutting into the collar. The outer threads are completely cut and I can now see the black filament. I love the collar but this is just not practical for daily. use.

a sweet, low-profile collar

  • Gender: Female
  • Familiarity: I've put it through the wringer

I got this for my dog (he's a husky-mix). Love: it has a really low profile, the climb-inspired attachments are very simple and sleek, the tags go on a separate ring and there's a rubber circle on the ring to reduce jingling
Don't love: my dog is a bit of a puller on the leash, so if I just attach his leash directly to this collar, the rope tends to stretch out a bit after a while.
That said, I usually attach his leash to a chest harness, so the collar really just acts as a tag-holder most of the time. As such, it's perfect.

Bomber Collar!

I am all about Ruffwear gear, and this collar is no exception! Our 7 month old Newf pup is a growing little beast, and she just outgrew the knot-a-just dog collar, so I picked up this one as a replacement (size L). And I'm liking it better thus far! The rope isn't that thick, which I was originally worried about, but I actually like the lower profile.
It's designed so that you can easily adjust the fit, but the pup can't pull against you hard enough to loosen it accidentally. And above all else, I LOVE that the ring is on the back, rather than down by their tags. It's super easy to find every time. I always had trouble finding the ring on our newf's old collar because she has such a thick scruff, but this collar definitely fixed that. And the lichen green looks good with the black fur too!
In the end, it's better than I was expecting, and I would definitely recommend!

Responded on

Alright, after a few weeks of constant use, I have a bit more insight on this collar. I still love it, and most of all how easy the ring is to find. The rope is nice, especially for longer haired dogs because it doesn't tug on their fur. However, the collar seems to loosen itself- or our pup is secretly taking off her collar when she's in the kennel. When the collar first arrived, the knots were super tight, and I had to yank on them to tighten it. However, little miss Newfie has figured it out and keeps coming up to me with a looser collar than when I left her.
Still love the collar, still super cute, but probably not the best choice for a tugger!
