Thank you for stopping by! If you are looking for a particular Jane Walker fabric collar and don't see the style/color please inquire. I have most of the designs and colors but there are so many I don't have all the samples made up. The collars shown are martingale collars for dogs with a larger neck than head. Greyhounds can slip out of a regular buckle collar. Most collars can be made in either a 1", 1 1/2" or 2" width. If you need a buckle collar feel free to ask. I also make collars with your choice of fabric. Please feel free to contact me with any questions.
