No slip collar or leash should ever be left on a dog that is tied up or unsupervised. If you’re going to use your slip leash as a pressure release training tool, please seek the advise of a professional trainer. No tool that can apply pressure should ever be used lightly or without proper training. Our recommendation is always to base your training in the LIMA method (Least Intrusive, Minimally Aversive)


1/4"*6mm) Diamater
5 foot (152cm) full length

Black Brass Matte O ring (this is a solid brass ring with black coating that can wear with time)

Suggested Dog Size 
0-45kg (This is based on our below recommendation, not the strength of the leash or hardware used)

Whilst 1/4" Beta Biothane rope has a break strength of over 200kg, for dogs larger than 45-50kg or those that pull very heavily, the rope can feel thin and uncomfortable to handle. It also may not effectively slide through thick double coated breeds as easily due to the soft light nature of the leash. We would recommend using the heavier duty 5/16" diameter granite biothane slip leashes for these dogs. 

All metal can and will rust or corrode when used in water, especially salt water! We highly recommend washing off your leash on a regular basis with clean fresh water and drying it off. The length is inclusive of the Biothane in the handle and the loop.

The best I’ve used

I couldn’t be without it these slip leashes, so light yet stong, waterproof, don’t slip down and great colours.
My clients and I love them.


Purchased at the dog lovers show stand last year and couldn't go past the colourful leads hanging by. This leash is super strong, the slip leash is easy to loop around the head and it doesn't clump up at the neck (releases when no pressure). I also like that it's easy to clean after getting dirty from being thrown around at a trail or in the car. The only thing is I wish the stopper was a bit smaller, but all in all a great product.


Great quality - 5 stars. Lead feels really nice to use and is a good length. Was recommended by my dog trainer. My order arrived extremely quickly. Thank you!
