If any one is looking for a Martingale collar for their Greyhound or any other breed of dog I would recommend Kitsch Collars .The Collars are all hand made and have Brass fittings. You can have the collars in two widths 40mm or 50mm .50mm preffered for a Greyhound.
Kitsch Collars make the working collars for our kennel and gives us these at cost price which is a huge saving to the kennels, so it would be nice if we could give her some trade .Dolly also has 3Greyhounds of her own, so any one
looking for collars please look at Kitsch Collars and try to help some one who helps GRF

I couldn't agree more. The collars are really well made as well as looking lovely. My dog has a narrow tag collar she wears all the time, and the martingale is added for walks.
I would also recommend the velvet leads. They're comfortable to hold and just the right length.
