Kooloop Dog Collar Review and Giveaway

Kooloop is a unique, high-quality dog collar that adjusts as your puppy grows so you don’t have to buy several new collars over a short period.

Not only that, but it’s a collar that’s built to last even once your dog is full grown. The collar adjusts when you slide it in 1 mm increments, so you always have a perfect fit. It’s designed as a walking collar, allowing you to get a proper, snug fit so your dog will never slip out of the collar.

Plus, the collar’s “double cam” lock has been tested up to 220 pounds.

My thoughts on the Kooloop collar

I really like this collar!

It’s high-quality and made with bright, modern colors. I trust that the double cam lock will hold up to my strong weimaraner, and because it’s so adjustable (1 mm increments) it’s easy to get a perfect fit.

This collar is designed to grow and adapt with your puppy so you don’t have to buy multiple collars. I can definitely see the benefit in that.

My weimaraner is 13 months old, and he still hasn’t grown into the most recent buckle collar I ordered him from another company! Oops! I assumed he would end up at least as big as my Lab mix Ace but turns out Remy is going to be smaller than I thought.

With the Kooloop collar, you can easily adjust to get the perfect fit even if you’re not quite sure on your dog’s size or when he’ll stop growing.

The collar comes in orange, red or blue and in two sizes:

Medium to large: 14″ to 24” padded

Medium to XL: 12″ to 26” non-padded.

Note that the largest collar is also the collar that adjusts the smallest.

We received the collar for medium and large dogs, and it adjusts to fit both Ace’s neck size (21”) and Remy’s (17”).

What is the cost of the collar?

Kooloop is an Australian company. The cost of a Kooloop collar is $32.95 (USD), plus shipping (around $5).

The collar comes in two sizes (up to 24” and up to 26”).

What’s unique about Kooloop’s collar?

The unique thing about Kooloop’s collar is how it adapts as your puppy grows. It will fit most medium, large and XL puppies and dogs.

The collar’s double cam safety lock locks both ways with strength up to 220 pounds so it will actually hold up to those crazy adolescent dogs who pull (Remy!). Yet, it also has a quick release which allows you to adjust or release the collar with one push.

Pros of the Kooloop collar:

  • I trust it will hold up to strong pullers (although you may want to use your typical training collar for walks)
  • No need to buy multiple collars as your puppy grows (save money)
  • Bright, modern colors and design
  • Made with UV resistant material
  • Adjustable in 1mm increments for a perfect fit
  • Heavy duty and high quality, but not heavy
  • One collar adapts to fit most medium to XL dogs
  • Comes in two size options
  • Every collar comes with a 1-year warranty


  • Best for medium, large and XL dogs but might be too big for smaller breeds. (It adjusts down to about 12”)

I would recommend this collar for …

I would recommend the Kooloop collar for anyone with a medium or large-breed puppy. It really is worth it to have a collar that adjusts as they grow, and this is a nice-looking collar.

If you like the modern, sporty look of this collar as I do, I also recommend a Kooloop collar for any medium or large breed. Remy is unlikely to grow much more (he’s 13 months) but I think this collar looks really nice on him. It’s durable but also lightweight.

I would love to win this collar for my dog. He's hard to see because he's so small, he's a 4 lb. Chihuahua but to get it on him I have to turn the collar into a harness so it will fit him. He loves his walks and I love that my Goliath will be seen on our late night walks.

I not only train dogs, I'm service dog trainer who actually works one on one to teach (mentor) a person to train their own service dog. While rescues often make great therapy and service dogs, I get many folks who choose a puppy. This collar is interesting, but somewhat expensive to recommend.

I have just adopted a puppy and would love to try out this brand. I have never heard of it but love the fact that it would adjust as my fur baby grows. ‍⚕️
