Anyone know where you can buy a Rope Slip Collar in White.

Is it for bull terriers or similar as Dajan do cord leads for these, also braid. http://dajan.co.uk/Cord.html

It for an aussie in the show ring but just need the collar.

hessonite?

There all leather I want rope

I think if you get in touch with dajan she will make just a collar ....

Sorry yes they are very accommodating. 

I always order the Braid half check collars in the size up to 14 inches (so last from puppy to adult) but order the weight chain suitable for a 20kg dog as they normally come with a lighter chain.

So I am sure he will do you something in the cord.  He recently had an accident and lost the end of his left index finger so has been slowed down somewhat.
